Descripción: In the last years, there has been much effort in commercial compilers to generate efficient SIMD instructions-based code sequences from conventional sequential programs. However, the small numbers of compilers that can automatically use these instructions achieve in most cases unsatisfactory results. Therefore, the code often has to be written manually in assembly language or using compiler built-in functions to achieve high performance. In this work, we present source-to-source transformations that help commercial vectorizing compilers to generate efficient SIMD code. Experimental results show that excellent performance can be achieved. In particular, for the problem of matrix product (SGEMM) we almost achieve as high performance as hand-optimized numerical libraries. Our source-tosource transformations are based on the scalar replacement and unroll and jam transformations presented by Callahan et all. In particular, we extend the use of scalar replacement to vectorial replacement and combine this transformation with unroll and jam and outer loop vectorization to fully exploit the vector register level and thus to help the compiler to generate efficient SIMD code. We will show experimentally the effectiveness of our proposal.
