Cannot find Xeon with OpenCL drivers with SYCL support

Luigi-Crisci — Thu, 07 Apr 2022 16:13:17 GMT

Hi,

I'm trying to run a sycl app using DPC++ Spir-v backend but I'm facing a lot of issues with installing the right opencl driver.

Configuration

Ubuntu 20.04 (Docker)
Intel(R) Xeon(R) Gold 5218
Intel DPC++ (built from source, release Release oneAPI DPC++ Compiler 2021-12 · intel/llvm (github.com)

Description

I tried to download the OpenCL CPU Runtimes for Linux from there: OpenCL™ Runtimes for Intel® Processors
After the installation, clinfo returns the correct device but I can't compile even a simple sycl app using the CPU backend (-fsycl-targets=spir64_x86_64)

Looking at the opencl runtime page, I saw that there is a dedicated section for opencl runtimes with SYCL capabilities, so I tried to download the intel-oneapi-opencl-runtimes from the apt repository.
However, no OpenCL devices are found with clinfo with this method.

Am I missing something?

Hi,

> However, no OpenCL devices are found with clinfo with this method.

Did you set oneapi environment before clinfo command?

For example, setting oneapi environment via command "source /opt/intel/oneapi/setvars.sh", then use "clinfo -l" command, all the devices are displayed.

Thanks
