Hello Michael,

your posting prompts me to the more general question: are there any (free)  
routines available for PARIX to do global broadcasting? 
We have the need for a global broadcast in our application (called EGO) and  
at the moment we use a loop and SendNode() to achieve this. The PVM, which is  
available on top of PARIX, does offer such a broadcast and at the moment we  
are investigating if using PVM/PARIX could speed up our application. However,  
having an optimized broadcast() at the PARIX level would surely be better.  
Does anyone have any pointers??

Thanks in advance,
Helmut Heller
