Profiling OpenMP Offloading Quiz

Question 1

Which NVHPC tool provides a system-wide performance overview, including both CPU and GPU activity?

  • A) Nsight Compute
  • B) Nsight Systems
  • C) rocprof
  • D) AMD uProf

Answer: B) Nsight Systems

Question 2

True or False: Nsight Compute is used to analyze system-wide performance, including CPU-GPU interactions.

Answer: False Explanation: Nsight Compute is a kernel profiler focused on GPU performance analysis, while Nsight Systems provides system-wide profiling.

Question 3

What command is used to collect performance traces for OpenMP Offloading applications using rocprof?

  • A) $ rocminfo --trace --target example
  • B) $ rocprof --hsa-trace --hip-trace ./example
  • C) $ rocprof --metrics gpu,hip ./example
  • D) $ rocprof --cuda-trace --hsa ./example

Answer: B) $ rocprof --hsa-trace --hip-trace ./example

Question 4

True or False: The rocminfo command provides trace information about OpenMP kernel execution.

Answer: False Explanation: rocminfo provides system-level details about ROCm-enabled devices and configurations but does not collect trace information.

Question 5

Which modules are required to compile and run OpenMP Offloading applications with GUI profiling tools on NVHPC?

  • A) NVHPC, CUDA, Mesa, Qt5
  • B) ROCm, hipcc, AMDuProf, LLVM
  • C) NVHPC, OpenACC, Mesa, Qt6
  • D) Mesa, ROCm, LLVM, NVHPC

Answer: A) NVHPC, CUDA, Mesa, Qt5
