Hi,

We have MPICH on a 8 processor SGI Power Challenge. But It seems
to have some problems when I ran my code. Sometimes the run will
succeed, sometimes fail. I don't know what is wrong. Even my
process number is smaller than the physical processor number and
I was the only user on the machine. Here are two of the
typical error messages:

jewel% mpirun -np 6 a.out
p0_18212:  p4_error: MD_initmem: usinit failed: cannot map shared arena
: 16777216

jewel% mpirun -np 6 a.out
rm_l_2_18320: (1.998727) Listener: Unable to interrupt client pid=18319.


I will appreciate any comments.

Jun Zhang
