Hi ,
	I have installes pvm version 3.3.4 on a cluster of HP
workstations.
There seems to be a problem with this version though!
If a group of tasks use the DontRoute option then the daemon
hangs!!
This seems to occur only after a flush of messages: a typical scenario:
let tasks 1,2 send 10 (small) mesgs to task 3 using the DontRoute
option.
What happens is the task 3 gets all mesgs from task 1 (or 2) but gets
none
from task 2 (or 1). Tracing the code I found that it seems to hang in
the mxfer() routine because mxinput(topvmd) seems to return 0??!!
What is the problem I am totally zonked on this - but it seems VERY VERY
strange.

Does anyone else have these problems ??
Any help/suggestions/pointers will be greatly appreciated.

Thanks

krishnan.
