Hello,
Thanks for the reply. But I have not killed the job. First time I waited for
more than a day. But the file was stuck at that reading point. I wrote so,
because I could not see any such parsing program or any such program which I
could related to PBSA calculation while I checked the list of running
programs using 'ps -A' or 'top' linux command. Also I used the output files
from the run and tried to run the mm_pbsa_stastistics.pl alone on the *out*
files as
nohup ~/SWare/amber10/src/mm_pbsa/mm_pbsa_statistics.pl 2 2
snap_statistics.in snap_statistics.out &
As I could monitor the command running as mm_pbsa_statistics.pl using
'top', it seemed the command ran for about an hour, and then it just
disappears without error. I am speculating may be its the RAM problem
(since its showed usage of RAM for > 86%), so I am thinking of transferring
the calculations out on higher RAM machine. Any other ideas?
Regards
Monika
