David,

After some searching it seems that Xcode had to be installed again using High Sierra. I was able to successfully configure CUDA with clang properly after reinstalling xcode. However, upon running make install I receive the following output leading to an error message:

cd /Users/kadirozcan/amber16/AmberTools/src && /Library/Developer/CommandLineTools/usr/bin/make install

Hello David,

Thank you for the quick response.


 1. My AmberTools17 is fully updated (./configure returns with no patches available for AmberTools 17).
 2. I have CUDA 9.0
 3. When enter ?which gcc? I receive the output ?usr/bin/gcc? as you predicted.
 4. ?./configure -clang ?? may have been a typo. I am using the command ?./configure -cuda clang? to which I get the error:

Thanks for the email. We are using AmberTools17.

The line 244 of $AMBERHOME/AmberTools/src/sander/rdparm.F90

is reading iscratch and ffdesc. I don?t know what that section is for.



Here is the code:

230 ! format should be (nlines, text) where we read the first lines
nlines

231 ! to know how many more lines to read - we ignore nlines on
subsequent

232 ! lines but they still need to be there.

233 ! e.g.

234 ! 2 PARM99

235 ! 2 GAFF

236 read(nf,fmt) nlines,line

237 allocate (ffdesc(nlines), stat = ierr)

238 REQUIRE(ierr==0)

239 ffdesc(1) = line

240 #ifndef API

241 write(6,'(a,a)') '| ',ffdesc(1)

242 #endif

243 do i = 2, nlines

244 read(nf,fmt) iscratch,ffdesc(i)

245 #ifndef API

246 write(6,'(a,a)') '| ',ffdesc(i)

247 #endif

248 end do

Can you look at line 244 of $AMBERHOME/AmberTools/src/sander/rdparm.F90,
and see what section of the prmtop file is being read? (I don't know
what version of AmberTools you have, so cannot be sure where to look
myself.)

Once you know which section of the prmtop file is being read, you can
look to see if there is something odd about your file in that section.

...good luck....dac

Hello all,

Dear Amber Users

I am trying to convert psf file (which includes water and ions) to convert
to prmtop file to have same number of atoms in amber topology as in psf
file. I tried the following command in parmed

*chamber -top parm99bs0_all.rtf -param par_all36_prot.prm -psf ionized.psf
-crd ionized.pdb*
* -p protein1.prmtop -inpcrd protein1.inpcrd -cmap -verbose*

It gave me error saying

*Action chamber failed*
* UnhandledArgumentWarning: -p protein1.prmtop -inpcrd protein1.inpcrd
-cmap -verbose*

Isn't protein1.prmtop and protein1.inpcrd are output files.

Could you suggest any way to convert psf file to amber prmtop file.

Many thanks.

Ashutosh

Be sure you have installed updates at least up to update.8 for
AmberTools17: that is required for CUDA 9.0. (I'm guessing you have
done this, since I think you would have seen a different error message;
but it is best to check.)

cd $AMBERHOME
./configure -cuda gnu


Obtaining the gnu compiler suite versions, e.g.:
   gcc -v

What gcc compiler are you using? What is the result of typing "which
gcc"? of typing "gcc -v". If your gcc is /usr/bin/gcc, you are actually
using the clang compiler.

While ? ./configure -clang ? gives me the following error:

Is the above a typo? Can you confirm the exact command you used?

I'd recommend installing gnu compilers from a distribution like
macports. But that doesn't explain the messages you are getting. We
need the information requested above to be of much help.

This doesn't look like the arguments to the chamber action: type "help

As the help page indicates, there are no "-p", "inpcrd", "-cmap" or
"-verbose" flags. (Are you copying from the now-obsolete stand-alone
program called chamber?)

You basically use the first two lines above, then use the "parmout"
action to specify an output prmtop file, and a writeCoordinates action to
specify an ouptut file for the coordinates.

Are you referring to AuCl as a solid, somehow interacting with a
protein; is there water around? (Note that AuCl has a tendency to
disproportionate into metallic Au and AuCl3 when in contact with water.)

For such a situation, MCPB won't help: it is designed for situations
where cation and anion dissoicate, and the metal cation is bound to
protein atoms.

A small additional tip -- you can see an example of how to use the
"chamber" command in parmed by looking at the relevant tests.

Look at $AMBERHOME/AmberTools/test/parmed/chamber/parmed.in for details.

This doesn't look like the arguments to the chamber action: type "help

* UnhandledArgumentWarning: -p protein1.prmtop -inpcrd protein1.inpcrd

As the help page indicates, there are no "-p", "inpcrd", "-cmap" or
"-verbose" flags. (Are you copying from the now-obsolete stand-alone
program called chamber?)

You basically use the first two lines above, then use the "parmout"
action to specify an output prmtop file, and a writeCoordinates action to
specify an ouptut file for the coordinates.

...good luck....dac

Dear Vincius,
Thank you for your mail. You were right that I had not set the
icnstph flag for the equilibriation. When I include that flag,
the equilibriation fails with the same error as before.
"forrtl: severe (18): too many values for NAMELIST variable"
It must be something wrong with my cpin file, but I cannot
figure out what that might be. I did create a new cpin for the
explicit simulations. I have been trying to titrate HIP, CYS, LYS
and TYR residues on my protein. So the equilibriation currently
fails when I use the cpin generated using following command -
cpinutil.py -p test.prmtop -resnames HIP LYS CYS TYR -igb 2 -o test.cpin
-op test.mod.prmtop
However, it runs successfully when I use the cpin from
cpinutil.py -p test.prmtop -resnames HIP LYS CYS -igb 2 -o test.cpin -op
test.mod.prmtop
Is there a limit on the maximum number of residues that can be allowed to
titrate? Could
that be the reason for my error?
Appreciate your help with this.
Thank you
Maya

Hello Maya,
The cpin file will not be read unless icnstph=1 or 2, thus it was not read
during your equilibration. The cpin file for a implicit solvent simulation
is not going to be the same as for a explicit solvent simulation. Did you
use cpinutils.py to generate a new cpin for the explicit solvent
simulation? Just for testing, try to run a single simulation with icnstph=2
and without pH-REMD just to see it works.

Dear David,
It's not clear exactly what program you tried to compile and execute.
I've attached my version (bench_nm.nab), along with the output from
"./a.out gcn4p1".  I hope this helps you find the problem.
Again, since we don't know what output you really got, it's hard to say
whether something is wrong or not.  You asked for 0 eigenvectory (eigp),
so you won't get a vecs file in that case.
Thank you very much for your answer. Indeed I used a similar nab script as the one  you attached (bench_nm.nab), and as you said my problem was that I was setting eigp the (4th argument in the nmode routine) as 0, and this prevented the vecs file from being created, as I did not ask for any eigenvalue to be computed.
So, in order to get the first 10 normal modes, I changed the following bench_nm.nab script lines:
// get the normal modes:
nmode( x, 3*m.natoms, mme2, 0, 0, 0.0, 0.0, 0);
to:
// get the normal modes:
nmode( x, 3*m.natoms, mme2, 0, 10, 0.0, 0.0, 0);
Compiled the nab script, and then executed:
/bench_nm.nab gcn4p1 > stdout_nmodes.txt
Finally I got the vecs file with the normal modes on it, and the stout_nmodes.txt file. The stdout_nmodes.txt contained basically what you posted as output for your "./a.out gcn4p1" execution (I copied most of it below). I believe that the reduced masses for each normal mode should be in this txt file. How can I find these reduced masses? Thank you again,
Lorena

$AMBEHROME/AmberTools/benchmarks/nab/benchamarks/nab/ directory but got
this when executing:
It's not clear exactly what program you tried to compile and execute.
I've attached my version (bench_nm.nab), along with the output from
"./a.out gcn4p1".  I hope this helps you find the problem.
I also tried to use the script bench_nr.nab with the
gcn4p1 example. I used the pdb, top and x files from
$AMBEHROME/AmberTools/benchmarks/nab/benchamarks/nab/. I added to the
end of the script the same line that is described in the manual to
calculate normal modes ( nmodes( x, 3*m.natoms, mme2, 0, 0, 0.0, 0.0,
0)), but I got a stdout that didn't seem to contain the full information
on the normal modes (reduced mass, frequency and displacement vectors
for each atom). I was expecting a vecs file, but didn't get one.
Again, since we don't know what output you really got, it's hard to say
whether something is wrong or not.  You asked for 0 eigenvectory (eigp),
so you won't get a vecs file in that case.
..good luck....dac

Hello Maya,
Yes, there is a limit in the total number of residues. If you want, you may alter the following block at $AMBERHOME/src/pmemd/src/constantph.F90 and recompile pmemd.
! Limits on the sizes of the data structures
#define MAX_TITR_RES 50
#define MAX_TITR_STATES 200
#define MAX_ATOM_CHRG 1000
#define MAX_H_COUNT 4
However, it is advisable to reduce the number of residues in your cpin file rather than doing this. Increasing the number of residues reduces the computational efficiency of your simulation. In general, people only consider the residues of interest for titration at a given value of pH (or pH range) instead of titrating all possible residues. You may run a short simulation titrating all just to check which residues are important to you.
I hope this helps,
All the best,

Dear Vincius,
Thank you for your mail. You were right that I had not set the
icnstph flag for the equilibriation. When I include that flag,
the equilibriation fails with the same error as before.
"forrtl: severe (18): too many values for NAMELIST variable"
It must be something wrong with my cpin file, but I cannot
figure out what that might be. I did create a new cpin for the
explicit simulations. I have been trying to titrate HIP, CYS, LYS
and TYR residues on my protein. So the equilibriation currently
fails when I use the cpin generated using following command -
cpinutil.py -p test.prmtop -resnames HIP LYS CYS TYR -igb 2 -o test.cpin
-op test.mod.prmtop
However, it runs successfully when I use the cpin from
cpinutil.py -p test.prmtop -resnames HIP LYS CYS -igb 2 -o test.cpin -op
test.mod.prmtop
Is there a limit on the maximum number of residues that can be allowed to
titrate? Could
that be the reason for my error?
Appreciate your help with this.
Thank you
Maya

Hello Maya,
The cpin file will not be read unless icnstph=1 or 2, thus it was not read
during your equilibration. The cpin file for a implicit solvent simulation
is not going to be the same as for a explicit solvent simulation. Did you
use cpinutils.py to generate a new cpin for the explicit solvent
simulation? Just for testing, try to run a single simulation with icnstph=2
and without pH-REMD just to see it works.

However, whenever i include the icnstph=2 parameter, I get the following
error
message *"forrtl: severe (18): too many values for NAMELIST variable" *
pointing
to the input cpin file. I did not have any problems using the same cpin
file
for the equilibriation run without the icnstph=2 parameter, or with the
entire imlicit solvent tutorial.I am not sure if I am doing something wrong
in combining the two tutorials. Would appreciate help with this issue. I am

Amber doesn't compute reduced masses for normal modes.  I guess you
would have to write a script yourself to do this: the masses are in the
prmtop file, and the eigenvectors are in the vecs file.
Note that cpptraj can read in eigenvector files and work with them.
Perhaps that might do what you really want. That is, why do you want to
get the reduced mass?  (One reason we don't compute these is that I've
never needed it, and no one else has ever requested it, as far as I can

And now for a public service announcement...
Recently on the list people have been writing in asking about the speed of
pmemd, of its GPU acceleration, which simulation program to use, and so
forth.  One newcomer even asked whether the GPU code is faster than sander,
and reading between the lines I can see a PI or two wondering whether the
Amber package, as opposed to the freely distributed AmberTools, is worth
the investment.  While I'm not here to advertise per se, I will offer the
following observations, which should help anyone trying to understand the
current state of the field, how fast is Amber, and where the technology is
taking us.
Elmar Krieger, perhaps my European doppleganger for the way he ebbs from
force fields to simulation methodology and back, published a fascinating
article back in 2015 showing how they took a single Core i7-5960X Haswell
processor and pushed the dihydrofolate reductase (DHFR, explicit water
molecules) simulation throughput from a humdrum 7.5 ns / day reference (1
fs time step, long cutoff) to run more than 20x faster through a series of
approximations that they demonstrate to be safe:
https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fonlinelibrary.wiley.com%2Fdoi%2Ffull%2F10.1002%2Fjcc.23899&data=02%7C01%7CKadir.Ozcan%40jefferson.edu%7C514ae750bba944ed9a8c08d5a49581ca%7C55a89906c710436bbc444c590cb67c4a%7C0%7C0%7C636595884398705623&sdata=1Fw31nftt46tBidnIkO0Pqd7PeRF2ntnUEp%2FzJw8%2BoE%3D&reserved=0
This is a big achievement--given the way they talk about AVX instructions
and their proximity to the GROMACS folks I'm going to assume they coded it
'right' and can't get their YASARA program significantly faster under the
same approximations on the same hardware.  The paper says "a single Core
i7-5960X" but that's a capital C--they use all eight cores, 16 threads, of
the hyperthreaded Core i7 processor, and I am going to assume that they're
not turbo-boosting because their program is running consistently enough
that there's not much opportunity for the chip to safely ramp up the clock
speed on any particular core.
First, let's compare the nuts and bolts of YASARA to what Amber's primary
simulation engine, pmemd, does.  We have something almost identical to DHFR
in terms of atom counts and run conditions (most significantly, PME and
8.0A cutoff): we call it JAC and you can find it on our benchmarks page:
https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fambermd.org%2Fgpus%2Fbenchmarks.htm%23Benchmarks&data=02%7C01%7CKadir.Ozcan%40jefferson.edu%7C514ae750bba944ed9a8c08d5a49581ca%7C55a89906c710436bbc444c590cb67c4a%7C0%7C0%7C636595884398705623&sdata=x8s3sCtTBlLGEUNWlqGNhSHSskF%2F%2BtlAJ2ozWdHV3hw%3D&reserved=0
Off the cuff, YASARA looks like it might be a bit faster than our pmemd CPU
code, but not tremendously so until they start invoking more drastic
approximations (we kind of part ways once they get to the lime green line
on Figure 8, when we use heavy hydrogens to get to a 4fs time step and they
use LINCS with multiple time steps).  We maintain an 'air tight' pair list,
which guarantees that every interaction within the stated cutoff is going
to be counted (there was a kerfuffle on the listserv a few months back when
I said there was a chink in the armor with Amber16, but we've patched
that).  YASARA takes a GROMACS-like approach with what they call a "sloppy"
pair list, which one can reasonably argue is no more an approximation than
hard truncation of vdW interactions or the tail of the erfc(r)/r function
in PME.  Krieger and Vriend then get another impressive boost from atomic
instructions (for those unfamiliar, this is a fundamental problem of
parallel computing, and works like a library checkout system so that common
pieces of memory can only have one thread operating on them at a time).
The additional boost that they then get from a more advanced method for
ensuring that threads don't negate one another's results is small, but they
get another big jump by writing their program to avoid the need to worry
about threads crossing paths in the first place.  Newer vector instruction
sets add a little more, and their "densostat," which approximates the
effect of a barostat but merely works to keep the simulation box size where
the user thinks it should be as opposed to where the Newtonian physics
would actually take it, is an 8% boost, comparable to the effect we see for
invoking or removing a virial calculation.
Now back to logistics.  There are a couple of facts pertinent to the
questions on the listserv that are not in the paper: the price of that
high-performance Haswell processor (currently about $900, on clearance as
it has been succeeded by the new Skylake line), and the power envelope
(140W).  The price of the modern equivalent Core i9-7960X Skylake is about
$1400.  Skylake doubles the number of cores and threads, but the clock
speed is back down, the cache is not that much bigger, and the power
envelope has gone up to 165W.  Tick, tock, tick, tock.  I'm just going to
estimate that on a new Skylake Krieger and colleagues might be able to get
DHFR to run at 250ns / day.  As stated above, the approximations made by
pmemd and YASARA are not comparable, and not everything that Krieger does
on a CPU will map to a GPU although a good portion of it will.  But let's
go ahead and compare the results to our GTX-1080Ti benchmarks.  The new
pmemd.cuda is somewhat faster than the Amber16 code, and I have more
optimizations in my own branch, working within our original set of
approximations and running the JAC benchmark at 730ns / day.  A GTX-1080Ti
cost $700 when it was new, and while the forthcoming GPUs will almost
certainly be more expensive thanks to the diligence of coin farmers, I
don't expect the price of a new Volta-like GTX to crest much above $1100.
Let's just stick with last year's model, though.
The GTX-1080Ti is a 250W card, but on the JAC/DHFR benchmarks it doesn't
ramp up completely (system isn't big enough), so the power consumption is
around 175W.  The GPU is therefore beating the CPU by a factor of nearly 3
in speed, for half the cost, and only slightly more electricity consumption
(running a 250W GPU round the clock for a year at 0.12 cents per kW/hr will
run you about $260).  As I said, JAC can't fully occupy the GPU--bigger
systems run up to 30% more effectively, with the throughput reaching a
plateau for systems about 3-4 times the size of JAC.  In contrast, Krieger
shows that the CPU offers nearly linear returns as a function of system
size, with slight degradation due to the O(N log N) property of the FFT.
(The FFT scaling is a weak effect on GPUs, which in fact do FFTs very
efficiently and reach peak efficiency in the FFT at about the same time
they reach peak efficiency in other aspects of the algorithm.) So on bigger
systems the GPU will retain its advantage in terms of power consumption and
grow its lead substantially in terms of throughput.  Of course, if we were
to invoke some of the approximations that Krieger shows on the CPU, our GPU
performance would likewise benefit.
As I said, I'm not doing this to advertise, and I'm certainly not doing it
to call out Krieger and Vriend for their statement that the technological
revolution that took computational science to GPUs may be shifting back to
CPUs.  There is truth to that statement, and Elmar has done some fabulous
work which I also admire for the way he thought out of the box and ran his
dynamics without a Verlet pair list (have a look at mdgx).  However, it
underscores the current state of things: while CPUs are making impressive
gains of their own, GPUs retain a considerable lead in terms of simulation
speed and power consumption.  As long as NVIDIA continues to let us use GTX
for scientific applications, the GPUs have a considerable cost advantage as
well.
Another way to look at this is that CPUs devote a lot of their silicon to
cache, a dustbin of information that, at some time in the last few hundred
thousand transactions, was hauled in from RAM.  GPUs, by contrast, devote
much more of their silicon to arithmetic units, have very little cache, and
run at about half the clock speed of a CPU.  Aside from those differences,
the lithography and circuits are pretty much the same.  It pretty well
explains the differences in power consumption and throughput when you just
look at what each device is doing with the silicon.  In that sense, I would
expect GPUs to maintain their logistical advantages over CPUs for
compute-intensive operations.
In terms of programming, one must be mindful of the scarcity of cache on
each GPU "core" (the streaming multi-processor, of which the new Volta
architecture has 80 on an immense 81 cm2 die).  But, I feel that in their
paper Krieger and Vriend have touched on another aspect of the computing
revolution that is now flowing back to CPUs:
"Although compilers could in theory do [Advanced Vector Extensions]
automatically, it does not work well enough in practice. Instead, the
developer must write code that explicitly uses these instruction sets,
either by programming directly in assembly language, or by using
'intrinsics,' small C/C++ functions that operate on vector data types and
map almost directly to the corresponding assembly instructions, so that the
compiler has an easy job... one needs to rewrite or at least adapt the code
for each SIMD instruction set (and almost every new CPU comes with
additional SIMD instructions)."
For a long time, GPU programming was considered a barrier that saddled the
scientific computing revolution on the backs of a group of people who might
not be computer science geniuses but at least had invested something to
learn an advanced language.  In practice, the threshold for CUDA
programming is to understand that whatever instructions one writes will be
executed by some combination of 32 threads (32-way SIMT), how to manage a
very small cache effectively, and how big the GPU really is.  Otherwise,
CUDA is more or less like C.  The computer scientists behind GPUs work in
close concert with software developers to provide solutions to fundamental
parallel computing problems like atomic memory transactions and thread
synchronization, and the innovations have been truly impressive.  The
impetus may now be on Intel and other chip makers to provide compiler
support for C- and Fortran-level programming in ways that effectively
utilize vectorization and all cores of these increasingly multi-core CPUs.
The good, and the bad, of the GPU computing revolution is returning to CPUs
themselves.  The rosiest future I can foresee is one in which there are
multiple stages between the single-core CPUs of 2000 and the GPUs of today,
where we can all select our price points, the transitions for coding are
incremental, and the device distinctions boil down to how much of the
silicon is for math or short-term memory.  Until then, please just know
that Amber is as fast as we can make it go, and for anyone interested in
undertaking a significant MD project it is worthwhile to buy into the GPU
power offered with the licensed version.

Just my nitpick here, although it is not completely unimportant:
Both AmberTools and Amber are distributed via licenses that you must
agree to in order to use the codes:  these are GPLv3 for AmberTools, and
a more restrictive license (see our web page) for Amber.
The distinction Dave is referring to above is probably that AmberTools
has no license *fee*, in contrast to Amber.

This is a different message than you reported before.  So, the obvious

As far as I can see, this error has nothing to do with cuda.  For some

I am performing TMD and have amber version 14. When I use a single

This is not unusual.  Sander rarely scales beyond a single node, or a
few dozen MPI threads.  You could try a sample run without targetting,
but I suspect that any job that goes off-node or beyond 32 threads is
likely to show decreased, rather than increased, performance.

I'll also add that Amber 18 brings with it significant performance improvements (in some cases > 20%) over Amber 16 on the same hardware. I'll be updating the GPU benchmarks page over the weekend to reflect the new performance benchmarks so please stay tuned.

Just my nitpick here, although it is not completely unimportant:
Both AmberTools and Amber are distributed via licenses that you must
agree to in order to use the codes:  these are GPLv3 for AmberTools, and
a more restrictive license (see our web page) for Amber.
The distinction Dave is referring to above is probably that AmberTools
has no license *fee*, in contrast to Amber.

Thank you very much!
I removed a few amino acid types from the cpin file and I do not get the
error anymore!

Hello Maya,
Yes, there is a limit in the total number of residues. If you want, you
may alter the following block at $AMBERHOME/src/pmemd/src/constantph.F90
and recompile pmemd.
! Limits on the sizes of the data structures
#define MAX_TITR_RES 50
#define MAX_TITR_STATES 200
#define MAX_ATOM_CHRG 1000
#define MAX_H_COUNT 4
However, it is advisable to reduce the number of residues in your cpin
file rather than doing this. Increasing the number of residues reduces the
computational efficiency of your simulation. In general, people only
consider the residues of interest for titration at a given value of pH (or
pH range) instead of titrating all possible residues. You may run a short
simulation titrating all just to check which residues are important to you.
I hope this helps,
All the best,

Dear Vincius,
Thank you for your mail. You were right that I had not set the
icnstph flag for the equilibriation. When I include that flag,
the equilibriation fails with the same error as before.
"forrtl: severe (18): too many values for NAMELIST variable"
It must be something wrong with my cpin file, but I cannot
figure out what that might be. I did create a new cpin for the
explicit simulations. I have been trying to titrate HIP, CYS, LYS
and TYR residues on my protein. So the equilibriation currently
fails when I use the cpin generated using following command -
cpinutil.py -p test.prmtop -resnames HIP LYS CYS TYR -igb 2 -o test.cpin
-op test.mod.prmtop
However, it runs successfully when I use the cpin from
cpinutil.py -p test.prmtop -resnames HIP LYS CYS -igb 2 -o test.cpin -op
test.mod.prmtop
Is there a limit on the maximum number of residues that can be allowed to
titrate? Could
that be the reason for my error?
Appreciate your help with this.
Thank you
Maya

Hello Maya,
The cpin file will not be read unless icnstph=1 or 2, thus it was not
read
during your equilibration. The cpin file for a implicit solvent
simulation
is not going to be the same as for a explicit solvent simulation. Did you
use cpinutils.py to generate a new cpin for the explicit solvent
simulation? Just for testing, try to run a single simulation with
icnstph=2
and without pH-REMD just to see it works.
