I am basically re-calling a kernel function over and over http://stackoverflow.com/questions/36288766/opencl-cloo-out-of-resources-error with varying number of global/local work items to check timing. I leave the arguments the same and call the kernel starting with 2x2x2 global and 2x2x2 local and iterating uperwards checking only valid sizes. It works fine occasionally, but most of the time it completes about 30 or 40 Execute() calls and then crashes on the next Execute() call. Note: Execute refers to the OpenCL.dll on the computer. The stack trace Unity returns is NULL I assume because of the native code. Anyone have any idea what could be causing this? Note: This version of Cloo is Cloo-Unity from GitHub and I am using it in Unity. The equivalent OpenCL function being called when I get the error is clEnqueueNDRangeKernel(), but it is called Execute() in Cloo. Code Sample: //Setup inputs one time... foreach (var input in p_inputs) { inputs.Add(input.Function, input); profiles.Add(input.Function, new RunProfile(input.Function, input.Weight)); input.Input.Prepare(package[input.Function]); } //Profile... DateTime start; int g_state = 0; int l_state = 0; long[] g = new long[3] { 2, 2, 2 }; long[] l = new long[3] { 2, 2,
Preset="Very Slow", TR2=3, TFF=True, Denoiser="KNLMeansCL") Works great. In a batch file (with multiple VS rendering http://forum.doom9.org/archive/index.php/t-173421.html jobs queued), however, I got an "Out of resources!" OpenCL error on the second job! I waited half a minute or so, and tried the second https://forum.byte-welt.net/archive/index.php/t-3900.html job again, after which it went thru fine. So, does your GPU need like a 'settle' period before it can accept the next OpenCL job? And, out of if so, how long? Thanks.

It's a GTX 980 Strix, and it's an OpenCL monster, really. After I built-in like a 30 secs delay between jobs, the error never recurred. Khanattila28th April 2016, 15:15LOL, yes.

It seems that the nVidia driver for Windows 10 is not sufficiently stable. It presents unique problems. vBulletin v3.8.9, Copyright ©2000-2016, vBulletin Solutions, Inc.
documentation says the following: CL_OUT_OF_RESOURCES if there is a failure to queue the execution instance of kernel on the command-queue because of insufficient resources needed to execute the kernel. For example, the explicitly specified local_work_size causes a failure to execute the kernel because of insufficient resources such as registers or local memory. Another example would be the number of read-only image args used in kernel exceed the CL_DEVICE_MAX_READ_IMAGE_ARGS value for device or the number of write-only image args used in kernel exceed the CL_DEVICE_MAX_WRITE_IMAGE_ARGS value for device or the number of samplers used in kernel exceed CL_DEVICE_MAX_SAMPLERS for device. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. The problem I am having with this strange occurence of the error in my code is that it happens at random on a random kernel each time all throughout my code. Sometimes it does crash and sometimes it doesn't and it's really driving me mad. Here are some system specs: - Nvidia Geforce GT 130M - Version: OpenCL 1.0 CUDA - Driver 296.10 (I got this information using GEEKS 3D GPU Caps viewer) I do not run out of memory. I always release my memory like it should. It seems like it also crashes more often when running multiple test cases in a row. But sometimes it also just crashes on the first case. The error is a CL_OUT_OF RESOURCES like stated earlier and the line that the error points to is clEnqueueNDRangeKernel. In what direction should I look to solving this error? Could it be hardware related? Driver related? Thanks in advance Xor Marco1318.04.2012, 19:51Hi Unfortunately, this is one of the most unspecific errors, and really hard to debug. Not only due to the second paragrap
