- Opens
- Create a continuous integration framework (https://github.com/triSYCL/sycl/issues/53).
- Development update for past two weeks:
- USM feature is committed
- Compilation with libcxx (https://github.com/intel/llvm/pull/358)
- Images and hierarchical parallelism in progress.
- New extension documentation for function pointers support in review: https://github.com/intel/llvm/pull/353
- Windows support update.
- Driver improvements: new options to simplify AOT compilation.
- Sync with the latest LLVM + automatic merge.
Participants: Alexey Bader(Intel), Mike Kinsner(Intel), James Brodman(Intel), Ronan Keryell(Xilinx), Andrew Gozillon(Xilinx), Victor Lomuller(Codeplay), ... (I think I didn't capture a couple of people)
No
Create a continuous integration framework (https://github.com/triSYCL/sycl/issues/53)
Ronan: There is no continuous integration system for Xilinx FPGA. We would like to configure something like travis to catch Xilinx FPGA specific issues introduced by changes in https://github.com/intel/llvm project.
Alexey: Intel team uses internal machines for CI system for several reasons. Open CI systems like travis have a number of limitations (e.g. job execution time < 1h, no more than N parallel jobs, etc.) and in addition to that this project requires specific HW (e.g. access to GPUs).
Alexey: to test Intel FPGA HW we use "FPGA emulator" running SYCL code on CPU, which is much faster than testing on real HW.
Ronan: Is there any interest in organizing SYCL specific session at LLVM developers meeting? Round table or BOF.
Victor: BOF about SYCL or more about offloading?
James: Generality could be good, but we need to avoid making it CUDA topic.
Alexey: Who should send a proposal?
Ronan: Intel should push as it drives the upstreaming effort. BOF/panel participants include multiple companies: Intel, Xilinx, Codeplay, ANL, RedHat?.
Andrew: A lot of tests failing. Need to resolve generic pointers.
Alexey: Please, open an issue and ask Andrew Savonichev for advice how to handle these failures.
