Abstract
In many iterative solvers for systems of sparse linear equations Sparse Matrix­ Vector Multiplication (SMVM) is a critical computational kernel. In this work we use FPGA as a accelerator attached to a host processor (ALTIX supercomputer) to accelerate SMVM. However, due to the large data requirements performance heavily depends on by memory bandwidth which is very limited on the ALTIX platform. Input data are streamed through FIFO buffers, which simplifies portability to another platforms with...
