hi,

a question concerning pvm_reduce: 
how does it collect the data??? i mean, how does it send messages???
i could imagine process i+! sends its data to process i and 
performs the dual operation and this is repeated until i=root (0).
or they may all send their data at once to the root.
or they may collect in groups of 2/3/... and then ...

please answer via e-mail

thanks

michael
