Subject: Re: [OMPI devel] How to disable paffinity
From: Ralph Castain (rhc_at_[hidden])

The rsh component checks for the existence of "fork", which may not be present in vxworks. Is it? I'm afraid that component uses fork, so you may have to create a vxworks component that doesn't, or at least uses the equivalent.
