Dear All,

I am struggling with porting OpenFoam to my IRIX with "-parallel" option on. That means I can run the solvers without "-parallel" very well, but as I mpirun my solver, it failed with annoying coredump. The output is at the bottom of my post.

what I don't understand is these lines in argList.C:
-------------------------------------------------

wordList machinesInfo(1);
machinesInfo[0] = hostName();

labelList pids(1);
pids[0] = pid();

if (parRunControl_.parRun())
{
if (Pstream::master())
{
machinesInfo.setSize(Pstream::nProcs());
pids.setSize(Pstream::nProcs());

// From all slaves
for
(
int slave=Pstream::firstSlave();
slave<=Pstream::lastSlave();
slave++
)
{
label slavei = slave - Pstream::masterNo();
IPstream fromSlave(slave);
fromSlave >> machinesInfo[slavei] >> pids[slavei];

}
else
{
OPstream toMaster(Pstream::masterNo(), 0, false);
toMaster << machinesInfo[0] << pids[0];
}
}
}
-------------------------------------------------

1. How can pids[slavei] get 4 (in my case) different pid()? The reason I raise the question is because I found my pids[1] is zero, and my machinesInfo[slavei] is empty! that's strange.
2. Is there a way to store the 3 slave (in my case) pids? (they are : 513638,513610,513608.)

Please help! Thanks in advance!

Daniel
