Support Intel® GPU

Hardware

Intel® GPU List

HALO supports Intel® GPU by Intel® oneDNN. Please check the supported GPU list in oneDNN website.

Here is the list copied from oneDNN:

  • Intel Processor Graphics based on Gen9, Gen9.5 and Gen11, and Gen12 architectures
  • Intel Iris(R) Xe graphics (formerly DG1)
  • Future Intel Arc(TM) graphics (code name Alchemist and DG2)

Driver

Please refer the Intel® software for general purpose GPU capabilities to install the driver and softwares.

Check

In Ubuntu, please install tool:

sudo apt update
sudo apt install clinfo

Run the cmd to check the Intel GPU is ready:

clinfo -l
or
sudo clinfo -l

For Gen9, the result is:

Platform #0: Intel(R) OpenCL HD Graphics
 `-- Device #0: Intel(R) Graphics [0x5927]

Build HALO to support Intel® GPU

Set oneAPI Packages

source /opt/intel/oneapi/compiler/latest/env/vars.sh
source /opt/intel/oneapi/dnnl/latest/env/vars.sh
source /opt/intel/oneapi/dpl/latest/env/vars.sh
source /opt/intel/oneapi/tbb/latest/env/vars.sh

Build HALO with Intel® GPU

Add -DODLA_BUILD_DNNL_GPU=ON in cmake cmd:

cd heterogeneity-aware-lowering-and-optimization
mkdir build
cd build

cmake -DCMAKE_BUILD_TYPE=Release -DODLA_BUILD_POPART=OFF -DODLA_BUILD_TRT=OFF -DODLA_BUILD_DNNL_GPU=ON -G Ninja ..
ninja

There will be file ./lib/libodla_dnnl_gpu.so to be created.

Build Binary to Support Intel® GPU

Set path for binary and library:

export HALO_ROOT=/xxx/halo
export PATH=$HALO_ROOT/heterogeneity-aware-lowering-and-optimization/build/bin/:$PATH
export LD_LIBRARY_PATH=$DNNLROOT/lib:$HALO_ROOT/heterogeneity-aware-lowering-and-optimization/build/lib:$LD_LIBRARY_PATH

Add -lodla_dnnl_gpu in link cmd.

Test the Binary in Host
