Building Nwchem against a separate GA library

Gets Around	4:41:33 PM PST - Thu, Feb 20th 2014 Hi, i have a couple of questions regarding Global Arrays. Nwchem build process seems to be coupled to the GA source distributed in the Nwchem tarball. 1. I would like to know about feasibility of building Nwchem against the version of Global Arrays available in Fedora/RHEL: http://pkgs.fedoraproject.org/cgit/ga.git/tree/ga.spec 2. Is the GA version distributed by Nwchem modified for the purpose of Nwchem or is it simply a snapshot of the GA repository? 3. Is API or behaviour of GA version distributed with Nwchem modified compared to http://hpc.pnl.gov/globalarrays/? Best regards, Marcin

However, a quick browse shows me that the RPM is configured for Infiniband (export GA_CONFIGURE_OPTIONS="--with-openib"). I doubt that this is an appropriate choice, since I have no idea of what happens when the SW runs on on HW that is NOT Infiniband HW 2. We have not modified the GA distributed by NWChem in recent years, but we could occasionally do it. 3. Not sure how to reply on this because of what I said for 2.
