Hello,
in some cases (about 5-10% of the jobs) pmemd jobs stop using the
assigned number of processors N and instead continue to run with N-1
cpus. This happends after a normal startup of the jobs and without any
obvious cause. PMEMD or mpiexec/mpirun don't return an error message but
continue to run normally, only in some of these cases it stops writing
output files. The same jobs run correctly after a fresh start.
The pmemd version is 3.1 compiled with ifc 7.1 and mpich-gm 1.2.5..10 on
a linux cluster with dual athlon nodes and Myrinet interconnect.
Has anybody observed a similar behaviour of pmemd or can provide a
solution to this problem?
Regards
Florian Barth
