While running an mpirun job on my dual-processor SMP system
(FreeBSD 4-STABLE from August 28), my program (initiated with the command
line 'mpirun -np 2 ../sphagr') periodically dies, leaving a process that I
can't kill -9. Here's the top:
216 root 2 0 166M 113M select 1 27:44 3.22% 3.22% XFree86
327 jbarnes 2 0 72364K 58056K poll 1 6:53 0.00% 0.00% kdeinit
549 jbarnes 28 0 400M 90744K CPU0 0 3:02 0.00% 0.00% sphagr
267 jbarnes 2 0 23388K 10932K poll 1 0:42 0.00% 0.00% kdeinit
here's ps -auxw | grep sph:
jbarnes 549 0.0 8.7 410076 90744 p2 R 3:39PM 3:01.97 sphagr -p4pg
/usr/home/
jbarnes 550 0.0 0.0 0 0 p2 Z 3:39PM 0:00.00 (sphagr)
The 550 process I kill -9ed, but its still there, and now when I
try to kill it it says 'no such process'.
Has anyone else had any experience with mpi processes being
unkillable? Supposedly 5.3 has better SMP support -- might it solve this
problem? Thanks for your ideas,
- Jason Barnes
