Hashcat and OpenCL installation issue xeon E5-4640 - spyderboyant - 12-18-2021
Hi,
I am trying to get a DL380 Gen 8 with 4 x E5-4640 0 @ 2.40GHz working with hashcat under Linux 20.04LTS.
I have successfully installed “Intel® CPU Runtime for OpenCL™ Applications 18.1 for Linux* OS (64bit only)” and it sees my Intel CPUs but "clinfo" hangs when I run it. Also, when I try and run hashcat I receive an "clCreateContext(): CL_DEVICE_NOT_AVAILABLE " and also Device #1 "skipped"?
Any ideas what is wrong/missing?
thanks

Have you tried using Hashcat with Windows? Hashcat was originally made for Windows and runs with a lot less problems. I was using Linux and I was having issues I read what I have told you and I was up and running in a few minutes.
Open a command prompt drop the Hashcat .exe into it then run it like you would on Linux.
From what your read out says you don't have a GPU so you should probably consider running it on a cloud service. Your going to spend days running only a few hash's it's not really going to be worth it.
With the GPU in the CPU it's bad real bad. so bad it's not worth it. Put it this way Rockyou would take hours with the dedicated GPU with an actual GPU it's about a minute and a half.
You can force it to run device one with -d1 your going to be crawling though.
Put it this way with the right equipment Hashcat runs so good I've been using it since 2019 and I just registered here because I hit a strange problem.
The CL_DEVICE_NOT_AVAILABLE I kept getting when I was trying to use my rig that has an AMD GPU I switched to the Nvidia rig problems all solved.
If you have a Nvidia GPU just install CUDA and your basically done. That CL_DEVICE_NOT_AVAILABLE will have you tearing your hair out.

thanks for the prompt reply. I eventually got it working by locating the Intel OpenCL version 16.1.1 where I saw some blogs around getting the E5 4600 XEONs with Sandybridge needing this version.. . I have four E5 CPUs and am trying to crack some DES hashes and yes, although showing 64MCU, its slow... 27 years for 8 character password with 2 byte hash :-( Benchmark is:
Speed.#1.........: 17643.3 kH/s (58.78ms) @ Accel:16 Loops:1024 Thr:1 Vec:4
So back to the CL_DEVICE_NOT_AVAILABLE with the intel CPUs was caused by the newer intel OpenCL driver (18.1.1) not supporting the older CPUs.
I have a couple old Quadro 2000s lying around... I'l build up with these and see how I go..
