Process p =null;
p=Runtime.getRuntime().exec("/mpich-1.2.2.3/bin/mpirun -machinefile
/mpich-1.2.2.3/examples/jota/maquinas.dat -np 2 mmatrix" );
Mpirun runs mmatrix, and mpirun works but no mmatrix. I
I had the following as a result of this command:
/mpich1.2.2.3/bin/mpirun :line 1: 8131 Segmentation fault (core
dumped)/
/mpich1.2.2.3/examples/jota/mmatrix -p4pg /home/tania/PI8049 -p4wd
/home/tania
exit value: -117
I've already had this kind of problem when I used to call mpirun
without
being from java and it was related to available memory( the mmatrix
was
too big). I was wondering if it could be the same, do you think it can
be related to the available memory to the JVM??? Can I increase this
amount of memory??? Because, when I run the same command without being
from java, it doesn't occur.
Thanks a lot,
