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
