cuda libraries for solana

solana-perf-libs

CUDA, and more!

Building

After cloning this repo use the makefile in the root to build the tree with nvcc in your path:

export PATH=/usr/local/cuda/bin:$PATH
make -j

This should generate the libraries:

• libcuda-crypt.a - ed25519 verify (used by leaders) and chacha (used by validators) cuda implementations
• libcpu-crypt.a - CPU chacha encryption implementation, used by replicators (storage miners)
• libJerasure.so, libgf_complete.so - CPU erasure code library used for coding blob send

Copy those to the Solana repo:

cp src/release/libcuda-crypt.a $SOLANA_ROOT/target/perf-libs
cp src/cpu-crypt/release/libcpu-crypt.a $SOLANA_ROOT/target/perf-libs
cp src/gf-complete/src/.libs/libgf_complete.so $SOLANA_ROOT/target/perf-libs
cp src/jerasure/src/.libs/libJerasure.so $SOLANA_ROOT/target/perf-libs

Build Solana with the cuda & chacha features enabled:

cd $SOLANA_ROOT
cargo build --release --features="cuda,chacha"
