Hi everyone,

I've referred this to Jim Kohl and he's finding a solution but I thought
I'd multicast it to everybody and hopefully get a solution.

I'm having trouble spawning PVM programs that accepts input from stdin
in XPVM. I have an input file called "data" and I use redirection at the
command line. ie. vector_master < data.

Now the tasks spawn okay but they just sit there and do nothing. No
messages are passed. This applies to spawning at the PVM console as
well. Now, it actually works when run from the unix prompt (with pvmd
running of course). So Jim and I suspect it might be a path problem. He
suggested earlier that I use an absolute path name for the input file
but that did not fix things. And also, when I include the data inside
the source code (ie. no data file), the program works in XPVM. So its
the redirection of the data file that might be the problem. Also,
reading from a file from the program (using fopen() in C) has the same
problem.

Any ideas? Thanks.

Steve.
