Subject: Re: bitslice DES parallelization with OpenMP
Alexander,
Both patches compile under MacOS 10.6 using gcc-4.5 I downloaded from this site (http://hpc.sourceforge.net/). Here are the results on a 2.4 Ghz Core2:
Without OpenMP:
./john -test
Benchmarking: Traditional DES [128/128 BS SSE2-16]... DONE
Many salts: 2031K c/s real, 2035K c/s virtual
Only one salt: 1972K c/s real, 1976K c/s virtual
Benchmarking: BSDI DES (x725) [128/128 BS SSE2-16]... DONE
Many salts: 67763 c/s real, 67763 c/s virtual
Only one salt: 66457 c/s real, 66457 c/s virtual
Benchmarking: FreeBSD MD5 [32/64 X2]... DONE
Raw: 10267 c/s real, 10267 c/s virtual
Benchmarking: OpenBSD Blowfish (x32) [32/64 X2]... DONE
Raw: 622 c/s real, 620 c/s virtual
Benchmarking: Kerberos AFS DES [48/64 4K]... DONE
Short: 328499 c/s real, 328499 c/s virtual
Long: 1047K c/s real, 1047K c/s virtual
Benchmarking: LM DES [128/128 BS SSE2-16]... DONE
Raw: 29621K c/s real, 29680K c/s virtual
With OpenMP:
./john -test
Benchmarking: Traditional DES [128/128 BS SSE2-16]... DONE
Many salts: 3639K c/s real, 1866K c/s virtual
Only one salt: 3188K c/s real, 1677K c/s virtual
Benchmarking: BSDI DES (x725) [128/128 BS SSE2-16]... DONE
Many salts: 124314 c/s real, 63453 c/s virtual
Only one salt: 120334 c/s real, 62278 c/s virtual
Benchmarking: FreeBSD MD5 [32/64 X2]... DONE

Benchmarking: OpenBSD Blowfish (x32) [32/64 X2]... DONE

Benchmarking: LM DES [128/128 BS SSE2-16]... DONE
Raw: 29795K c/s real, 19398K c/s virtual
Without patching, the relevant results for DES and LM are shown below:
Benchmarking: Traditional DES [128/128 BS SSE2-16]... DONE
Many salts: 2279K c/s real, 2284K c/s virtual
Only one salt: 1971K c/s real, 1975K c/s virtual
Benchmarking: LM DES [128/128 BS SSE2-16]... DONE
Raw: 13027K c/s real, 13053K c/s virtual
