## MASS v6.0 -- High performance math libraries for POWER7
Mathematical Acceleration Subsystem (MASS) Version 6.0 for AIX has been released. This high performance suite of elementary and special mathematical functions contains two new libraries tuned for the IBM POWER7 processor, and exploiting the POWER7 VSX SIMD instruction set. MASS v6.0 offers performance on POWER7 of up to 260 times that of the system math library libm, and up to 4 times that of previous versions of MASS. MASS v6.0 ships with the IBM XL C/C++ for AIX v11.1 and XL Fortran for AIX v13.1 compilers, which provide for both explicit... [More]

## MASS auto-vectorization paper now on developerWorks
If your applications call mathematical functions such as sin, cos, exp, log, etc. and you are interested in maximizing performance with minimum effort, here is something that will interest you! My colleague Daniel Zabawa and I have written a paper, "How to improve the performance of programs calling mathematical functions -- taking advantage of IBM XL C/C++ or XL Fortran compiler auto-vectorization". Our paper introduces the IBM MASS high-performance mathematical libraries, and demonstrates how to benefit from them — without the need for... [More]

## MASS high-performance mathematical function libraries
Hello -- I'm the technical leader for the IBM MASS math libraries. MASS stands for Mathematical Acceleration Subsystem, and consists of libraries of mathematical functions specifically tuned for optimum performance on various computing platforms. MASS was originally launched by IBM in 1995, and has been continuously improved and expanded since then. I've been involved with MASS since 2002. There are currently versions of MASS for all the POWER processors, running AIX or Linux operating systems. There are also versions for BlueGene/L and... [More]

## Welcome to Scientific Computing with C/C++
Welcome to the blog on Scientific Computing with C/C++. IBM has a long history of Scientific Computing starting with the creation of FORTRAN in 1957 to the control systems for the Apollo missions in the 1960s. Today, various user groups and wikis exist to support IBM’s scientific computer users: SCICOMP (see http://www.spscicomp.org/ ) SPXXL (see http://www.spxxl.org/new_website/html/index.html ) HPC Central (see http://www.ibm.com/developerworks/wikis/display/hpccentral/HPC+Central ) My Name is Roch Archambault and I have over 20 years...
