I am using an AMD Llano APU to calculate some reasonably sized Linear Algebra problems. I can get the low-cost memory copies working through using the Map and UnMap fine but ... the problem sizes must be small. So I am guessing this is for them to fit into the 128MB on the GPU?
Is this correct - if I load too much data into a buffer than the kernel fails at submission time due to an out of resources error.
It seems a real pain that we could not fill up system memory and then use the GPU to process the data.
Did you watch the bios settings? (I have not Llano APU, but earlier i had similar problem with my integrated videocard.)
