Simplifying Low-Level GPU Programming with GAS

Requirements

• cmake >= 3.8
• g++ >= 9.2
• nvcc >= 11.0

Build

export GAS_HOME=$PWD

mkdir build
cd build
cmake ..
make # -j6

Run examples

1. benchmarks

cd examples/benchmark

# can replace cpi with L0-i-cache/L1-i-cache
cd cpi
make
./benchmark

2. hgemm (Require Turing devices)

cd examples/hgemm
make
./run.sh

3. sgemm

cd examples/sgemm
make
./run.sh

Troubleshooting

If cmake cannot find ANTRL. Copy bin/antlr-4.7.2-complete.jar to /usr/local/lib/antlr-4.7.2-complete.jar
