UHD730 does not work distributed.net OpenCL client

Hi,

I am trying distributed.net Windows 32bit [x86/OpenCL] client (https://http.distributed.net/pub/dcti/current-client/dnetc-win32-x86-opencl.zip) on Windows11 and it is not work with error -11 like this.

Maybe error -11 means CL_BUILD_PROGRAM_FAILURE. I also tried distributed.net Linux [AMD64/OpenCL] client with Debian12 on i7-7700 (HD630) machine, this works good.

It may be client program problem, but I think something incompatibility with host side as well.

I hope I can try this client on UHD730/Arc A380. Is there any good ideas to solve this?

Hi Hugo,

Recently I tried distributed.net client for Linux [AMD64/OpenCL] client (https://http.distributed.net/pub/dcti/current-client/dnetc-linux-amd64-opencl.tar.gz) on WSL2, it does not work as well but build log said that buffer overflow.

I hope this will be a hint to solve the problem.

I tried https://github.com/dcti/dnetc-client-base the source code of distributed.net client and I found following code in rc5-72/opencl/ocl_common.cpp make things worse.

status = clBuildProgram(cont->program, 1, &cont->deviceID, "-cl-std=CL1.1", NULL, NULL);

remove "-cl-std=CL1.1" solves this problem.

Recently I bought ASRock Intel Arc A770 Phantom Gaming D 8GB OC and I checked this on this board. But maybe same method can solve on UHD730, too.
