Hi,

I'm able to spawn some slaves (2-20) on my 24-node IBM-SP2-machine.
The master cannot communicate with the slaves.

The shell appears as follows:

pvm> conf
1 host, 1 data format
                    HOST     DTID     ARCH   SPEED
                     n12    40000   SP2MPI    1000


after running the master-programm:

pvm> ps
                    HOST      TID   FLAG 0x COMMAND
                     n12    40011       4/c -           
                     n12    40012     6/c,f slave1.host 
                     n12    60000       4/c slave1      
                     n12    60001       4/c slave1      
                     n12    60002       4/c slave1      
                     n12    60003       4/c slave1      


30 seconds after running the master-programm the slaves die:

pvm> ps
                    HOST      TID   FLAG 0x COMMAND
                     n12    40011       4/c -

I had no problems while compiling the slave whith the mpicc-compiler..
The pvml.uid - file didn't contain any information..
