Core LLama2.c Math Functions in LevelZero & SPIR-V

This repo shows a PoC with the core math functions in Llama2.c written for OpenCL and compiled to SPIR-V binary. The resulting SPIR-V kernels are dispatched using the Intel Level Zero API for Intel GPUs. Data is shared using Level Zero Shared Memory and Panama Segments.

Dependencies

• Intel Compute Runtime (GPU Driver): https://github.com/intel/compute-runtime
• Intel Level Zero Loader: https://github.com/oneapi-src/level-zero
• Level Zero JNI: https://github.com/jjfumero/levelzero-jni

Build

1) Build Intel/LLVM (If needed)

Compile OpenCL Kernel to SPIR-V

Use CLANG from the Intel/LLVM Fork:

git clone https://github.com/intel/llvm 
cd llvm 
python buildbot/configure.py
python buildbot/compile.py

## Export PATH to LLVM
export PATH=/home/juan/repos/SPIRV/llvm/build/bin:$PATH

Compile the OpenCL C kernels to SPIR-V using LLVM:

./createSPIRVCode.sh

2) Build Level Zero JNI Dependency

2.1 Compile Intel Level Zero Library

cd $LEVEL_ZERO_ROOT
git clone https://github.com/oneapi-src/level-zero.git
cd level-zero
mkdir build
cd build
cmake ..
cmake --build . --config Release
cmake --build . --config Release --target package

2.2 Compile the JNI Library

a) Compile the native code:

cd $LEVEL_ZERO_JNI
git clone https://github.com/beehive-lab/levelzero-jni.git
export ZE_SHARED_LOADER="$LEVEL_ZERO_ROOT/build/lib/libze_loader.so"
export CPLUS_INCLUDE_PATH=$LEVEL_ZERO_ROOT/include:$CPLUS_INCLUDE_PATH
export C_INCLUDE_PATH=$LEVEL_ZERO_ROOT/include:$CPLUS_INCLUDE_PATH
cd levelzero-jni/levelZeroLib
mkdir build
cd build
cmake ..
make

b) Compile the Java library:

cd $LEVEL_ZERO_JNI
mvn clean install

3) Compile corellama2.levelzero Java PoC Library

git clone https://github.com/jjfumero/corellama2.levelzero
mvn clean package

Run

/home/juan/repos/SPIRV/levelzero-jni/levelZeroLib/build/
java -Djava.library.path=$LEVEL_ZERO_JNI/levelZeroLib/build/ \
  -cp target/corellama2.levelzero-1.0-SNAPSHOT.jar:$HOME/.m2/repository/beehive-lab/beehive-levelzero-jni/0.1.3/beehive-levelzero-jni-0.1.3.jar \
