I just do my first tests on pvm so please be patient.
I just installed pvm 3.3.7 on a Linux-Cluster and everything seemed to
work well. But now it looks like as if there was a limit to the size
of the receive buffer. Sending more than 450 double values seems to be
no problem, but somehow they are not unpacked correctly. Unpacking
even leeds to a total crash of the pvm-machine. 
The example programs do not to bother about buffer size. So the
timing program coming with pvm sends very large arrays, but they are
not unpacked by the corresponding slave program.

Any hints or information?

Thanks in advance

Uwe
