Hello,
I am trying to do Replica Exchange calculations using Amber 9. When I try with
the files of the example of the tests, it works, but when I try with my protein
I have problems. Using directly the usual restart file from a sander calculation
I get problems of the type
[1] MPI Abort by user Aborting program !
[1] Aborting program!
[0] MPI Abort by user Aborting program !
[0] Aborting program!
srun: error: s30c1b04: task[0-1]: Exited with exit code 255
However, when I create the restart file from the trajectory file with ptraj the
calculation stops with no errors, but stop writting at the point (in the
rem.out files):
...................
trajectory generated by ptraj
begin time read from input coords = 0.000 ps
Number of triangulated 3-point waters found: 0
| Atom division among processors:
| 0 2573
| Running AMBER/MPI version on 1 nodes
| MULTISANDER: 2 groups. 1 processors out of 2 total.
....................
It creates the correspondent files reminfo and rem.log, but they are all empty.
In the error file I only can see "srun: Force Terminated job".
Since the same calculation works with the protein that appears in the test
examples, maybe could it be a problem of format? Should I do any special
treatment to the restart file I use for the calculations?
Thank you very much for you help, in advance.
