OpenBLAS is an open source BLAS (Basic Linear Algebra Subprograms) implementation, which is the building block of dense matrix software stack. Currently, OpenBLAS is used by high performance computing applications, and machine learning / deep learning applications.

The speaker introduces the work of porting OpenBLAS on RISC-V ISA. Furthermore, they presents how to optimize the software performance by RISC-V "V" Vector Extension, including GEMM (matrix multiplication), the BLAS level 3 function, and axpy, the BLAS level 1 function. Then, the speaker gives the performance benefit on XuanTie C910 RISC-V processor.
