Dear all,
I am currently engaged in GPU full system simulation using gem5 and am at a stage where I seek to run benchmark suites, specifically Rodinia and PolyBench.  I have observed that both of these benchmark suites support compilation for OpenCL architecture, and I have a few questions regarding the compilation and execution process within the gem5 environment.  Compilation Framework: Should I compile these benchmarks under the OpenCL framework? Is this the recommended approach for compatibility with the gem5 GPU full system simulation?

Utilizing ROCm in gem5: I noticed that the ROCm installed in the gpu-fs docker image includes OpenCL compilation tools. Is it feasible to directly compile these benchmarks within this environment? Are there any specific considerations or steps that I should be aware of? Guidance and Documentation: Would anyone be able to provide guidance or point me towards documentation on how to properly set up and execute these benchmarks in the gem5 GPU full system simulation context?

Thank you in advance for your time and assistance. I look forward to any suggestions or guidance you can offer.

Best regards,

Sandy.

Hi Sandy,

Depending on the benchmark, OpenCL might do an online compile (i.e., compile the kernels right before running them).  If you are using KVM it should just work.  Otherwise, the online compilation will take a significant amount of simulation time and offline compiling would be preferred (i.e., compile the kernels offline on the disk image).
