Hello,

I could need some advice:

here we have a relatively big piece of software that shall be ported to
Unix (and expanded) in the near future. This software consists of some
independently running processes (possibly on different machines of a
cluster) that need to send messages to oneanother. Currently these
messages are stored in temporary disk files.
We now think about other mechanisms of message transfer and ran across
pvm, so here the questions:

1) will there be a performance increase? The number of files written during
   one simulation is several thousands, average size ~100 bytes.
2) the program is written in ADA, is it possible to write only the
   subroutines concerning message transfer in C and link with the pvm_lib
   or does pvm require to compile the entire application in it's environment?

Thanks in advance
