Tests with HSA

[mateustsantos]

Hi, I am having trouble using hsa, all results from the GPU I get is SimTime, Frequency and Cycles, all other relevant information results in 0 using southern islands, even the CyclesPerSecond.The Mult2Sim provides the others informations?

How can I make it run with a selected AMD using the souther islands that Multi2Sim provides? Can you provide me an example? When I am running some tests It seens it does not link with the GPU I want, it always use the HSA instead of the selected configuration with the --si-config.

Thank you in advance.

May I know what you want to do here? Do you want to run Southern-island GPU simulation? Our HSA model only has emulation support, so you are expected to see SimTime be 0 since the execution time is not counted.

I would like to run Southern-island GPU simulation, what exactly I need to configure? If I use some benchmark that give support to GPU then will the Southern-island GPU simulation work just fine?

This is how I am trying to run:

./m2s --si-sim detailed --si-config /multi2sim/samples/southern-islands/7970/si-config /multi2sim/samples/hsa/histogram/hist

OK, so I realize what is the problem. The HSA sample uses HSA runtime which is not supported by the Southern-island detailed simulator. Multi2Sim will redirect the GPU execution to the HSA emulator. That is why you see the HSA section. Since no code is executed by the southern-island simulator, the time is 0, which is desired.

Currently, Southern-Island model only supports OpenCL runtime. There are some pre-compiled benchmarks can be found here.
