Critical OpenCL big affecting intel Graphics devices

[brichard19]

There is a critical OpenCL bug detailed here https://software.intel.com/en-us/forums/opencl/topic/801754

This bug affects the OpenCL version of Bitcrack. It will not find keys on some Intel graphics devices.

I will look into creating a work-around in the code until the issue is resolved.

Perhaps for the same reason AMD devices do not work correctly?

I have a laptop with Intel HD Graphics 620 and dedicated AMD Radeon 530. None of them works.

how to use multiple gpu? i add command in bat like -d 0 -d 1 not working... the software always use d 1 gpu

[brichard19]

@ayiphelmy Each instance can only use 1 GPU. To use multiple GPUs you will need to run multiple instances of the program.

in fact, on AMD devices, the not finding error is when the --keyspace parameter is specified.When we do not specify this parameter, the program works fine. As soon as the parameter is indicated, any range, then the result can be skipped. Hope for a quick direction from the developer. Thank you.

Hi. I downloaded all files. I typed the key I want to search in the keys section of the main file in the AddrGen folder. There is no activity currently. When I try to open .exe files it instantly shuts down. How should I go about it? What should I do?
