Subject: Re: bcrypt-parallella on 64-core (was: Katja's weekly
 report #13)


I run self test for bcrypt-parallella format 10 times and counted for each
core how many times it didn't start computation. Than I tried using only
cores that didn't start less than 3 times out of ten. Number of such cores
is 24.
Computation isn't started always but when it is, performance for those 24
cores is 1807 c/s (I'm transferring data buffer with data for all 64
After this I tried to use cores that failed 3 times (10 more so 34 in
total) but I tried 10 times and it didn't work - some cores always fail to
start computation.
