Hi,

I am (a newbie) looking for some advantages and disadvanges of using PVM 
over 
a *real* parallel machine, points specfic to PVM inplementation with C and 
Unix would be nice.

At present I am using PVM for performace evaluation purposes of parallel 
applications. I am finding the 
results (times) I get flutuate a great deal, the performance of running 
applications 
on PVM seem to be dependant on many other things e.g. network, other 
running processes etc, is this 
a disadvantage? can I achieve near constant application performace over a 
PVM?

Of course cost is a big plus point, but what are the 
others?

Regards

S.
