[mvapich-discuss] viacheck.c error

[Sayantan Sur]

Hello Alicia,

Thanks for reporting the error. As you said, the error appears after 
calling "system" from within an MPI program. The "system" call involves 
an internal call to fork(). As of OFED-1.1, fork() is *not* supported by 
the underlying InfiniBand libraries. I believe OFED-1.2 will support fork().

Thanks,
Sayantan.
