These two functions get the best gpu threads and the best keys per crypt of your sistem. find_best_workgroup is on by default you can make it run for your preferred format and then suppress the test by doing export LWS=num be aware, best LWS changes from format to format . find_best_kpc is off by default; you activate it by doing export KPC=0 and, after the test you can suppress it by doing export KPC=num . if you don't export a KPC it will use max_keys_per_crypt. be aware that kpc is highly dependant on the specification of your hardware and the format you are using. nsldaps, raw-md5, mysql-sha1 raw-sha1 now all support password up to 31 lenght. raw-md5 and nt have been modified to gain some speed. raw-md4 at the moment is left out but it will back in the tree as soon as some problems are fixed. > The "magnum-jumbo" tree is now 120+ commits ahead of Jumbo-5: Perhaps > it's time for a Jumbo-6? i would appreciate if people could test opencl formats and report strange behaviour or problems .
