Hello, recently I made the DarkNet on OpenCL that is technology that really passionate me and I started recently PhD studies on AI field. I am using few different GPUs, recently 2 x AMD Radeon VII that works very well... AMD OpenCL limits a single buffer allocation (CL_DEVICE_MAX_MEM_ALLOC_SIZE) to 50% of total memory. So on a 8Gb card there is only 4Gb available for allocation in a single chunk. This is very sad for ... OpenCL single memory allocation limit
BackTested on latest 19.10.1 drivers. Windows 10 x64 1903 I attached cl file and cpp program which would launch this simple addVec kernel. Opencl code: #pragma OPENCL EXTENSION cl_amd_printf : enable __attribute__((req... Strange printf behaviour on Vega
BackBack in the early days of OpenCL AMD added the famous cl_amd_media_ops (2) to expose hardware features to the programmers. Sadly with some of there more recent or more hidden hardware features like GDS or the cross la... Feature request: expose newer AMD GCN / RDNA features as CL extension
