建议暂缓购买。
大牛tear对目前的Xeon phi跑FAH的测试结果提出根本性质疑,他认为由于Xeon phi不支持SSE/SSE2指令集,应该不能直接跑smp2/bigadv包。
我觉得既然已经正式发售,最近应有更多的测试结果放出,建议先观望观望。

tear [H]ard|DCer of the Year 2011, 1.5 Years Status:
However you call it, these instructions are not present in its ISA == can't fold on any of the SMP FahCores.
EDIT: That said, the only option to fold on Phi is using GROMACS on OpenMM-on-OpenCL or porting GROMACS' "kernels" to Phi's ISA or (possibly) using GROMACS C kernels + intel's autovectorization.
I honestly doubt any of these have been done...
