2019 09 09 meeting notes

Agenda

• Opens
• SYCL development status update
  • Added SYCL compiler build instructions on Windows
  • SYCL runtime is built with Khronos ICD library by default (instead of system OpenCL)
  • Enable typedef-ed kernel names support (https://github.com/intel/llvm/issues/130)
  • Intel FPGA extension to simplify device selection
  • Various USM fixes and improvements
    • Added ordered queue extension support
  • Added "deploy" target to install SYCL toolchain only
  • Added "run on the host" Intel extension. This method allows enqueuing host tasks into SYCL queue.
  • Enabled re-interpretation of 1D sub-buffers
  • No OpenCL API calls in SYCL headers -> no need to link with OpenCL.
• In development features
  • using sycl = cl::sycl; alias to reduce code verbosity
  • Split device code into multiple SPIR-V modules. Current proposal - split per translation unit.
  • Documentation improvements
• LLVM dev round-table topics
