Questions tagged [hip]

Key features include:

  • HIP is very thin and has little or no performance impact over coding directly in CUDA or hcc "HC" mode.

  • HIP allows coding in a single-source C++ programming language including features such as templates, C++11 lambdas, classes, namespaces, and more.

  • HIP allows developers to use the "best" development environment and tools on each target platform.

  • The "hipify" tool automatically converts source from CUDA to HIP.

  • Developers can specialize for the platform (CUDA or hcc) to tune for performance or handle tricky cases

How does the rocm runtime schedule inactive wavefronts?

I used ROCM to compile the HIP program. When a simple, but thread-intensive HIP program was run, I used ROCgdb for debugging and found that using the "info threads" command did not see the expected number of wavefronts. I have compiled the rocm…
