garymm / xpu

XPU

single source that compiles to run on both GPU and CPU

Set up

Currently only supported on Linux x86_64 / AMD64.

• Install bazel or bazelisk

• Verify that you can build and test:

bazel test //...

And with CUDA:

bazel test --cuda //...

Status

SYCL

• Got it building and running with OpenSYCL on CPU / OpenMP.
• Doesn't work with nvc++ possibly due to an nvc++ bug. AdaptiveCpp/AdaptiveCpp#1052.
• Got it building and running with Intel DPC++ on CPU and GPU, but not through bazel.

HIP
