Installing OpenBLAS

Before configuring the compilation environment, install the BiSheng Compiler and Hyper MPI, and import the BiSheng Compiler and Hyper MPI environment variables. If the BiSheng Compiler and Hyper MPI have been installed in the environment, directly import their environment variables.

Decompress the OpenBLAS installation package.
```
unzip OpenBLAS-0.3.6.zip
```
Go to the directory generated after the decompression.
```
cd OpenBLAS-0.3.6
```

Perform the configuration.

export CC=clang
export CXX=clang++
export FC=flang

Perform the compilation and installation.

make
make PREFIX=/path/to/OPENBLAS install

Load the environment variables.

export LD_LIBRARY_PATH=/path/to/OPENBLAS/lib:$LD_LIBRARY_PATH
