Subject: OpenCL CL_INVALID_DEVICE (-33) error in opencl_common.c:452
Hello, I'm having problem running john using multiple GPU devices on the
same system. I have no idea what this error meant.
OpenCL CL_INVALID_DEVICE (-33) error in opencl_common.c:452 - Error
querying PLATFORM_NAME
As you can see below, I have 2 GPUs on this system. so --devices=0,1
--fork=2 is correct, I am assume.
tezos@...os-Desktop:~/JohnTheRipper/run$ ./john --devices=0,1 --fork=2
--format=tezos-opencl --session=tezos tezos
Using default input encoding: UTF-8
Loaded 1 password hash (tezos-opencl, Tezos Key [PBKDF2-SHA512 OpenCL])
Cost 1 (iteration count) is 2048 for all loaded hashes
Will run 4 OpenMP threads per process (8 total across 2 processes)
Node numbers 1-2 of 2 (fork)
