It doesn't, and I think it didn't.

d1a.log.gz downloadable from here:

gives this:

=== Testing sha512crypt-opencl on MIC ===
Device 1: Intel(R) Many Integrated Core Acceleration Card 
Exit code: 139

139 means segfault.

Now that I've tried bleeding-jumbo on our 5110P, I am getting results
similar to what Mr Dupito posted.

I suggest that we create you an account on our machine with the 5110P,
and you debug the issue.

Note that Mr Dupito was testing with john-1.7.9-jumbo-7, whereas we may
only care to get bleeding-jumbo to work on more hardware.
