AMD Details hUMA: HSA in Action!

Recommended Posts

When GPU computing came on the scene it was full of great promise.

The idea of a heavily parallel processing unit that will accelerate

both integer and floating point workloads could be a potential gold

mine in wide variety of applications. Alas, the promise of the

technology did not meet expectations when we have viewed the results

so far.

Quote: "Standalone GPUs can benefit from HSA, but not to the extent of

an APU. A dedicated GPU will have its own attached memory as well as

shared memory with the main CPU. Due to the communication latency

issues of writing from main memory to the video cardÂ’s memory, it is

not nearly as seamless as what an APU can accomplish. It makes sense

that such a setup would benefit a solution with a shared memory pool

as well as a shared memory controller. Everything else involves more

latency and differing amounts and types of memory."


Thanks for a post!
