Subject: Re: [OMPI devel] 1.7.5 fails on simple test
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2014-02-10 17:34:20


The fastest of my systems that failed over the weekend (a ppc64) has
completed tests successfully.
I will report on the ppc32 and SPARC results when they have all passed or
failed.
