Subject: Agnieszka's weekly report #6
accomplishments:
- moved memory allocation in pomelo beyond hash function
- I was working with threads on lyra and also moved allocation memory
in better place
- I optimized my parallel-opencl results:
[a@...er run]$ ./john --test --format=parallel-opencl --dev=1
Device 1: Tahiti [AMD Radeon HD 7900 Series]
Local worksize (LWS) 64, global worksize (GWS) 16384
Benchmarking: Parallel-opencl [SHA-512 OpenCL]...
DONE
Speed for cost 1 (s) of 0, cost 2 (p) of 0
Many salts: 46811 c/s real, 4915K c/s virtual
Only one salt: 46369 c/s real, 4915K c/s virtual
[a@...er run]$ ./john --test --format=parallel-opencl --dev=5
Device 5: GeForce GTX TITAN
Local worksize (LWS) 64, global worksize (GWS) 8192
Benchmarking: Parallel-opencl [SHA-512 OpenCL]...
DONE
Speed for cost 1 (s) of 0, cost 2 (p) of 0
Many salts: 46811 c/s real, 47261 c/s virtual
Only one salt: 47261 c/s real, 47261 c/s virtual
960m:
none@...e ~/Desktop/gcnn/run $ ./john --test --format=parallel-opencl
Device 0: GeForce GTX 960M
Local worksize (LWS) 64, global worksize (GWS) 32768
Benchmarking: Parallel-opencl [SHA-512 OpenCL]...
DONE
Speed for cost 1 (s) of 0, cost 2 (p) of 0
Many salts: 47836 c/s real, 48188 c/s virtual
Only one salt: 48188 c/s real, 47836 c/s virtual
priorities:
-I'll be working on lyra2 especially on that still my threads blocks
in version b) of lyra2. btw. I created my own barrier using mutex and
atomic operations but speed decreased from 9k to 3.5k.
