1) Questions and Answers : Unix/Linux : CL_OUT_OF_HOST_MEMORY with AMD RX 6600 XT on Xubuntu 20.04 (Message 74792) Posted 13 Dec 2022 by darknightcl Post: In case anyone else runs into this problem and happens to find this page, it took extensive research, but I think I know what's happened. In ~2017, AMD came out with a new opencl stack called Radeon Open Compute - runtime (ROCr), and started building it in to new GPUs. Specifically, anything newer than a Vega 10. In ~2019, the AMD GPU Linux driver was updated to deprecate the "legacy" opencl stack in favour of ROCr. According to the AMD GPU driver page, the legacy opencl stack doesn't support anything newer than the Vega 10. Newer GPUs must use ROCr. Since the apps for MilkyWay@Home haven't been updated since 2019, I assume that they haven't been updated to use ROCr, and therefore won't run on any of the newer AMD GPUs under Linux. This also explains why if you look at the GPU Models page under the Computing menu above, all the AMD GPUs listed running under Linux are older than the Vega 10. Long story short, MilkyWay@Home needs to update its apps.

4) Questions and Answers : Unix/Linux : CL_OUT_OF_HOST_MEMORY with AMD RX 6600 XT on Xubuntu 20.04 (Message 74758) Posted 9 Dec 2022 by darknightcl Post: I realize that this is an old thread, but is there any word on what we should do about this error? I have the same problem on my Radeon RX 6750 XT. Every task attempted fails with the CL_OUT_OF_HOST_MEMORY error. Should I let my computer burn through the bugged tasks? Should I disable the GPU for this project? Do the researchers know about this problem? Thanks!
