Subject: OMP & Compilation issues on OSX
Hi All,
Usualy, i use Version 1.7.9_OMP, but would like to update my build as well,
to get more improuvement & new aglo's on....
I have just read couples of the last threads, where users seem got problem
who look similar than mine.
I am on MAC OSX mountain Lion.
I use usualy JTR version 1.7.9 Jumbo who are avaible on the custom builds, =
http://openwall.info/wiki/_media/john/john-1.7.9-jumbo-7-macosx-Intel-2.zip
i make some tests with the Magnum build =
https://github.com/magnumripper/JohnTheRipper
Because i would like to update....
& Unfortunately not got the expected improvement...
Look,
On the version 1.7.9
ver: 1.7.9-jumbo-7_omp [macosx-x86-64]
=
pc2:run1 xxxx$ ./john --format=des --test

****************
On the last version from Magnum Github, tested today
( i just do a classic compilation without touching any file or modify any
..., i just do $ ./configure & make, all is done without any errors )

Like you can see, seem OMP is not enable as the other 1.7.9 version who can
up at 15925 K C/S, Even in GPU Mode we can't get the expected improuvement.
I try to make test with the addition of "--fork=N" option, but got an error
message, seem we can not Mix " --fork=N & --test""....can you confirm this
point please ?
Any help with be appreciated,
Thank you in advance,
Regards,
Donovan
