Hi, I have to agree here. At least there should be a non-PCIe-3.0 pathway which implements them on the CPU, I mean, they're fairly simple atomics, CAS, SWAP, FetchAdd. What AMD have actually done is royally screwed over anyone with an FX chipset, i.e. no OpenCL - the open source AMD one requires

As I understand it, it would require changes in the ROCr Runtime and in the firmware (MEC microcode). It also changes the programming model, so it may affect certain applications or higher level language runtimes that rely on atomic operations. Regards,   Felix Am 19.12.2017 um 16:04 schrieb Tom
