Subject: phpass on CPU, aka dynamic_17
magnum, Jim, Lei -
As you are aware, unfortunately, disabling OpenMP for dynamic_* at
compile-time currently also applies to the phpass format (aka
dynamic_17), even though it is slow and should be scalable... but
surprisingly shows only 3.68 out of 10.0 at the test I just ran?!
(Lei's benchmarks on MIC also show this format behaving unexpectedly
poorly.)
Maybe you can look into getting both issues fixed: improving this
format's scalability and allowing for including OpenMP for it even when
other dynamic_* formats are built OpenMP-less?
Maybe we should simply (re-)create a separate phpass format, not
building upon the dynamic formats framework? IIRC, we had one before.
