Here is what I have already done and will do: In order to do reset/clear cache after self test. - I set a global variable(in_self_test) in format.c - In the begin of fmt_self_test(), in_self_test set to 0. And in the end of it, in_self_test set to 1. - In my format, I recorded and checked in_self_test, if it changes, I will call a reset In order to place hashes/salts on constant memory on GPU, I recorded 4000 hashes and salts by now. In format.h, we record hashes in a link list with salt. But copy a link list to GPU is complex and inefficient. - Allocate the same number of salts and hashes - For every hash, record its salts. Here we may record same salt multiple times The criteria for finishing loading all hashes is we see the first loaded hash twice. Move cmp_all to crypt_all - Compare loaded salts with given salt, if the same, compare the hashes (I think we have the hashes with same salt in consecutive index in the array. Because in crack.c, we pass hashes with same salt to cmp_all() ) - Record compare result in correspond array with hashes In cmp_all() - Check the array and return the result Thanks myrice
