Not sure if you can use all cores. It has been and still is my experience that SM is crap. We have several SM gpu and SM/Calxeda Arm clusters and they really lack in may ways from ipmi to chassis management to the corners they cut with the processor to memory mappings. I would consider looking at SGI UV, ultraviolet system for a fat node type system but they are not cheap. We have plenty of those and they can build it the way you want. Lead time is a couple of months due to build to order. Support from SM sucks too. :) On Sep 17, 2013 12:17 PM, "Michael Chen" wrote: > I'm considering bidding on this 48-core box: > > http://www.ebay.com/itm/**Supermicro-A-Server-1042G-TF-** > 1U-H8QG6-4-CPUS-48-cores-2-**2Ghz-128GB-RAM-/151119828428?** > pt=COMP_EN_Servers&hash=**item232f7195cc > > Does anyone have experience with it and can I use all the cores? > > Thanks! > ______________________________**_________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/**mailman/listinfo/freebsd-**questions > To unsubscribe, send any mail to "freebsd-questions-** > unsubscribe@freebsd.org " >
