I have a 280x Tahiti and it normally runs OCL for both Genefer (genefer 21) and Genefer_WR (genefer 22) but is running OCL4 after a fan died and overheated some (TThrottle to the rescue again) but now runs OCL4 even though it tries OCL fine via this message:

Using OCL transform Resuming 194778^2097152+1 from a checkpoint (23560318 iterations left) Estimated time remaining for 194778^2097152+1 is 20:30:00 Successful computation progress with OCL; switching back to OCL4. Using OCL4 transform


It usually take 15-17 hrs to run genefer 21 but it's at 35 hrs with 20 to go on OCL4. What's the cmdline to force OCL instead of OCL4 to add to app_config?

It's -x OCL if I'm not mistaken.

The parameter is "-x OCL", but that's not going to help you much.

Had you linked to the actual result, or had you included the entire stderr_out contents, I wouldn't have had to go searching for the tasks in question. I found two:

http://www.primegrid.com/result.php?resultid=862088229 and http://www.primegrid.com/result.php?resultid=861492379.

Your problem isn't that Genefer is running the wrong transform.

The problem is that the GPU is overheating and the calculations are failing. TThrottle may protect the GPU from damage, but the GPU isn't working correctly.

A larger, more informative clip from the output:

It starts using OCL, but it fails. It shouldn't be failing. As part of its error handling process, it tries other transforms. They work, and it goes back to OCL. But the calculation is already damaged.

I don't recall if the -x parameter will prevent it from switching in the case of an error. It's intended to bypass the benchmarks and tell Genefer which transform to start with. But if it doesn't downshift to another transform when an error occurs, its only other choice is to abort the task.

Your real problem is that the calculation is failing. "-x OCL" isn't going to solve that, however "-x OCL4" might. Forcing it to use the slower transform will probably use less power, produce less heat, and might be enough to prevent these errors. It will certainly run slower.

Wrong WU. The one you are referring to is a genefer 22 WU. This one is genefer 21. If I can't get this one running on OCL I might just abort it and start fresh but I'll give this one another try first.
This is the complete & correct stderr to the right one:

As you see it starts in OCL4, fails then switches to OCL then switches back to OCL4 then starts and stays there from then on. TThrottle is set to 82C now. I've run numerous genefer 21s as high as 88C successfully so heat shouldn't be the problem now. I tried -x OCL and nothing. What should the <app> to <app> contain in app_config? or other ways to force OCL?

EDIT: Even tried the following and still nothing: <cmdline>primegrid_genefer_3_3_2_3.18_windows_intelx86__openclatiGFN21.exe -boinc -q 194778^2097152+1 -x OCL</cmdline>

<cmdline>-x OCL</cmdline>


It doesn't work. That was the exact command line I tried before starting this thread. I guess I'll let it finish using OCL4, but would like to know all info for app_config for the future.

<app> ................ ................ ................ ................ ................ </app>


Please fill in relevant info to make it work.

Entire file for GFN21 on an Nvidia GPU:

<app_config> <app> <name>genefer</name> <fraction_done_exact/> <report_results_immediately/> <max_concurrent>1</max_concurrent> <gpu_versions> <gpu_usage>1</gpu_usage> <cpu_usage>.01</cpu_usage> </gpu_versions> </app> <app_version> <app_name><genefer/app_name> <plan_class>OCLcudaGFN</plan_class> <avg_ncpus>.01</avg_ncpus> <ngpus>1</ngpus> <cmdline>-x OCL</cmdline> </app_version> </app_config>


That file is a bit overzealous and includes several lines that may not be needed, but shouldn't hurt. The most likely reason it didn't work before is that you didn't include the correct plan_class tag.

A minimal file, that should also work, looks like this:

<app_config> <app> <name>genefer</name> </app> <app_version> <app_name><genefer/app_name> <plan_class>OCLcudaGFN</plan_class> <cmdline>-x OCL</cmdline> </app_version> </app_config>


I haven't tested either personally, but both should work. Good luck both with the XML, and with fixing the problem with your GPU.
