Hello,
thank you for the clarification. I must have misunderstood you.
Now i did it.The master node was in the example i send now exec-node01
(it varied from attempt to attempt). The output is in the master-node
file. The qstat file is the output of
qstat -g t -u '*'
That seems to look normal.
Now i created a simple C file with an endless loop.
#include <stdio.h>
int main()
{
int x;
for(x=0;x=10;x=x+1)
{
puts("Hello");
;
}
return(0);
}
and compiled it:
mpicc mpihello.c -o mpihello
and started qsub:
qsub -pe orte 300 -j yes -cwd -S /bin/bash <<< "mpiexec -n 300 mpihello"
The outputs look the same as for the sleep command above.
But now i counted the jobs:
qstat -g t -u '*' | grep -ic slave
This results in the number '300', which i expected.
On the execute nodes i did:
ps -ef | grep mpihello | grep -v grep | grep -vc mpiexec
(i counted the 'mpihello' processes)
This is the result:
exec-node01: 43
exec-node02: 82
exec-node03: 83
exec-node04: 82
exec-node05: 82
exec-node06: 80
exec-node07: 64
exec-node08: 64
Which gives the sum of 580.
When i count the number of free solts together (from 'qhost -q') i also
get 300, which i expect.
Where do the extra processes on the nodes come from?
This difference is reproducible.
libgomp.so.1.0.0 library is installed, but aqpart from that nothing with
OpenMP.
With kind regards, ulrich
