whale internally supports openblas, currently for Matmul (32-bit sgemm) in tensor. Right now it only supports Linux. To use openblas, make sure below are satisfied:
- openblas installed. See Installation Guide
- Header file must be named
/opt/OpenBLAS/include/cblas.h - Lib files must be in
/opt/OpenBLAS/lib/
- Header file must be named
- Shared object path is specified at build time (for static link) or runtime (for dynamic link).
- export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/OpenBLAS/lib
- export
- Go program is built with build tag
blasgo build -tags blas
If -tags blas is not specified, generic matmul implementation using pure Go (somewhat parallelized using goroutine) is used.
If openblas is not usable from Go while -tags blas is specified, the build or execution of the program will just fail.
Plotting requires gnuplot installed.
sudo apt install gnuplot-x11
