No work for OpenCL AMD cards.

Just got WUs Thanks.

There was a problem with translating --device to -d and parsing it inside the app.
I think it is fixed in 1.02 release because I've just seen a first completed and validated task.

Completed and validated Thanks.

For me the GPU app still only works on one GPU, allowing two WU's to run only runs them both on the same GPU which leaves any other GPU's doing nothing. For me at least nothing has changed :(

For sh#%s & giggles I even tried to changing the command to -d 1 in the job_160.xml file and another time tried pausing the WU and changing it in job.xml file in the slot directory but with the same result. As far as boinc is aware all is working as it should be with a WU running on each device but in reality there both being crunched by the same GPU.



I also did not have much luck with running 2 GPUs, but hopeful that the OpenCL/ATI version of GPU app will allow you to run
both NV & ATI GPUs cards in same rig.

Update to 1.08 is working well, 2 old Xeon rigs & 1 Dual-Core Processor can run GPU WU. Thanks.

Will the new build of enigma-cuda.exe, be implemented on the enigma server, or is there a cheat sheet for dummies ?


I'll update the apps on the server later today. GPU workunits generator will be stopped for around ~1h right before update.



Thanks for update.

A new build of enigma-cuda.exe is available. This build:

1) does not use AVX or SSE instructions (the speed is the same);
2) has a new command line option, -d <cuda device number> (0-based indexing).

The source and new binaries are here: https://github.com/VE3NEA/enigma-cuda

I have 4 rigs 2 t3500 Xeon machines. & 2 dual cores, 1 amd & 1 intel, that will not run the app
New install of win10 on the t3500 + VC2015 still no go. Pulled intel 2 core and install ( i5 4 core and it worked.)

How do I make the Xeon work, Thanks.
