Hi,
I want to perform LINPACK test on my m/c, I have only 1 GB RAM on the
m/c where I want to run 12 parallel Linpack processes on SLES 10.
I am using of Mpich-1.2.7p1. (Mpich is built with -rsh=ssh option)
I have modified HPL.dat accordingly,
P = 3
Q = 4 (so as to make PxQ = 12)
N = 8640 (so as to make use of only 56% of available memory
and leave rest for host processes)
NB = 11520
I have also set ulimit -l unlimited..
Created a machine.list file by specifying my m/c's IP address 12 times.
(So as to execute all 12 processes on the same m/c) and using GotoBLAS
for the Linpack execution
Execution command:
mpirun -np 12 -machinefile machine.list xhpl
Upon execution, I get following error:
HPL ERROR from process # 0, on line 419 of function
HPL_pdinfo:
>>> Need at least 12 processes for these tests <<<
Please guide me where am I going wrong
