I have 20M sha1 hashes that I'm trying to load. The GPU has 4Gb RAM. $./john John the Ripper 1.8.0-jumbo-1-5344-gefae4e5+ OMP [linux-gnu 64-bit AVX2-ac] $./john 20M.hashes --wordlist=uniqwords --pot=20M.pot --format=raw-sha1-opencl --session=gpu --fork=2 --rules:Jumbo No dupe-checking performed when loading hashes. Using default input encoding: UTF-8 Loaded 20000000 password hashes with no different salts (Raw-SHA1-opencl [SHA1 OpenCL]) Remaining 5347239 password hashes with no different salts Node numbers 1-2 of 2 (fork) Device 0: Hawaii Device 1: Hawaii / Progress is too slow!! trying next table size. \ Progress is too slow!! trying next table size. Progress is too slow!! trying next table size. (..) This message keeps going and going (30m at least) .. is there anything I could do? or is there some limit on the # of hashes (or wordlist size) that can be loaded using GPU? The wordlist is 200Mb.I tried with 5M hashes and the same behavior. I'm now trying with 1M .. but seems stuck as well... Thanks Luis
