Re: [AMBER] Problem while running MMPBSA

Hi Qi,

I looked at the files you sent me, and I see that the GB calculations
finish successfully and the PB calculations don't. However, like you
mentioned, the PB output files do not contain any error messages, so
there's no way of knowing exactly what's going wrong.

You are just running the tutorial (Ras-Raf binding) with the same input
files that the tutorial website shows, is that correct? Given your output
files, the nab executable is being used to extract energies from your
trajectory, which means the entire calculation is being done via AmberTools
12 -- not Amber 11.

I tried running the tutorial files on my machine, and it completed without
error. Unless you made changes to the files downloaded from the tutorial
website, my guess is that differences with your OS and/or compilers are
revealing a subtle bug somewhere (my guess is more on the compilers than it
is on the OS).

Can you provide the compilers and OS that you're using to build AmberTools
12 so that we may be able to track down why your calculation is failing?
 Without being able to reproduce the error you're seeing, we will have
trouble tracking down the problem.

As a reference, each frame should take ~300 MB of RAM (at least that's what
it did on my machine). If you are running in parallel (say, for instance,
on 12 threads), you will need 12 threads * 300 MB/thread ~= 3.5 GB of
available RAM to run your calculation. If you are running on a cluster
that uses some kind of resource manager (like PBS or torque), and you
haven't requested as much RAM as Amber tries to use, the scheduler may
silently kill your simulation with a potentially obscure message related to
using more resources than permitted, but this is just speculation.

Also, if you were running parallel (which it doesn't look like you were),
try running in serial to see if you reproduce the same error.

Hope this helps,
Jason
