Hello!

I have a problem with that my PVM-deamons crashes. I'm running PVM v3.3.3
soon 3.3.4 on an IBM RS/600 250. The deamons will crash when i'm using 16 of
these machines. Testing the program with 4 machines, it runs perfectly.

My program is a block-matrix algoritm, and i'm calculating a 600x600 matrix,
which works well on 1 and 4 machines but not on 16.

The program was first implemented for iPSC/2, and when i then converted it to
PVM, I had to add 6 more messagetypes, otherwise it wouldn't run at all. The
message types added was for redistributing the matrices the when doing the
actual sending of calculated data. (1 msgtype for each matric A, B and C). 

This are two problems, that I've encountered, the last one i can live with
but not the first. If anyone is intressed in the source code i could mail it
to you or to this newsgroup.

If anyone has had the same type of problem please let me know.

PS. Sorry about my bad english, i hope you understand anyway... :-) DS.
