Hi!

I've got problems with PVM version 3.3.5.

I just want to run the matrix multiplication example from the 
PVM3 users guide.
This programs runs without any problems.

I have another version of this program, where is have added only a 
few printf() lines. 

And then I get (mostly, but not always) this error message
at the following line of the source code:


[T2:t40005] 793467037.926973 pvm_send0(0x40004, 3)
[1:t40005] libpvm [t40005]: pvmmctl() connect: Connection refused

        pvm_initsend(PvmDataDefault);
        pvm_pkfloat(b, blksize*blksize, 1);
  =>    pvm_send(up, (i+1)*BTAG);

where  up = 0x40004.

The task with this taskid exists.

Does anybody know this problem and a solution for it?

Thanks in advance.

Ulrike
