That was with super's default gcc.  After "scl enable devtoolset-2 bash"
to enable gcc 4.8.1, I get:

Benchmarking: md5crypt, crypt(3) $1$ [MD5 128/128 AVX 4x3]... (32xOMP) DONE
Raw:    635904 c/s real, 19872 c/s virtual

and per my records, with some older versions of jumbo it was 638976 c/s.

So our target speed for Xeon Phi 5110P might be:

638976 * 60*512*1.053 / (16*128*2*3.0) = 1682104 c/s
