BLASTH, A BLAS Library for Dual SMP Computers
Guignon Thomas, Laboratoire ASCI
Abstract
This paper presents a multi-threaded BLAS library for dual SMP Intel computer
running Linux. We present simple techniques to obtain parallelism for BLAS
call transparently from the client program. We discuss some synchronization methods
available under Linux, show performances results for a representative
set of BLAS and for a high level linear algebra kernel. We then explain
some key points on cache management and how they can impact on performances of
the blasth library. Next we'll draw some conclusions on the use of SMP computer for linear algebra and present
evolution perspectives for the library.
