If you can do 1210 c/s while also using the two ARM cores for another 160 c/s (normally, they do 166 c/s in an OpenMP-enabled build of JtR), this gives us a nice 5000 c/s on 64-core. ;-) 1210*4 + 160 = 5000 That said, there is indeed more potential in using the FPGA than in further Epiphany and ARM code optimizations, so you should in fact focus on the FPGA soon. Here's some code from our 2011 project: http://openwall.info/wiki/crypt-dev/files This includes Eksblowfish in Verilog using BlockRAM in Spartan-6 or Virtex-6, but otherwise mostly unoptimized. Here are some thoughts on optimizing it: http://www.openwall.com/lists/crypt-dev/2011/08/21/1 You should also cleanup your bcrypt on Epiphany code and submit it for inclusion in the main bleeding-jumbo branch. BTW, I think the make target should be simply "linux-parallella" rather than the lengthy "linux-arm32le-neon-parallella". Thanks, Alexander
