However, when I bought the hardware, I was unaware that AMD hadn't fully implemented HSA on Richland (meaning there's no CPU<->GPU cache snooping and no shared memory address space).
Correction: Apparently there is cache snooping, through the Fusion Compute Link, but I don't see what good this does when the CPU and GPU can't address any of the same physical memory (I have to set aside a chosen amount of RAM for the integrated GPU in BIOS, and Linux sees that much less RAM). Can anyone clarify this, and/or comment on how hard it would be to make StarPU aware of the FCL?
