Hello, maybe it is worth to say something about running FreeBSD 10.1 RC2 on Supermicro H8QGi-F with 64 cores (4x16) and 512 GB RAM: first of all: it runs without troubles so far... I am working in the area of bioinformatics at University in Muenster - I run some test with blast, installed VirtualBox which is running Ubuntu 14.04.1...
