I’ve spent the last few months picking at a FreeBSD clustering project. Well, with some help from BSDHound and the Central Iowa Linux Users Group (CIALUG), it’s finally complete.
I clustered 4 Pentium 133s running FreeBSD 5.1-Release using LAM-MPI for the messaging interface and Ganglia for the monitoring. You can view the statistics here, but you must be registered and signed-in to do so (the pages are fairly graphic intensive).
I believe there will be a clustering How-To posted to BSDHound.com in the future, and if it is, I will be sure to post and update here.
