I'll test it on my cluster =) it uses infiniband and mvpich2 but some people want to use ordinary eth as interconnect so it will be very useful =) 2008/2/26, Justin Bronder <jsbronder@gentoo.org>: > I've been spending the majority of my Gentoo-related time working on a > solution to bug 44132 [1], basically, trying to find a way to gracefully > handle multiple installs of various MPI implementations at the same time in > Gentoo.
