   I was wondering how should programmer deal with I/O in
   PVM codes so that the program  can utilize the efficiency
   of parallel file system in MPP like Intel Paragon, but 
   doesn't lose the portability to workstations or any other
   architectures that don't support parallel file system.

   Please email your reply to this account:

   Thanks.

There is no portable parallel-I/O interface at this point, but there
are some possibilities that may help you. 

PIOUS is a parallel-I/O system designed to work with PVM; contact

		       pious@mathcs.emory.edu

Further information on PIOUS can be found in [1,2]; postscript versions of
these papers are available via anonymous ftp from ftp.mathcs.emory.edu:pub/vss
in the files piousifip94.ps and piousshpcc94.ps.

There is also a draft of a new interface designed to work in
conjunction with the MPI message-passing standard, MPI I/O; contact
Sam Fineberg fineberg@nas.nasa.gov.  This won't help you now but you
can still influence the future.
