SSI Libraries Available

14 Nov 2006

The Scalable Software Infrastructure Project, supported by the "Core
Research for Evolutional Science and Technology" (CREST) program of the 
Japan Science and Technology Agency (JST), is pleased to announce 
the first major international release of our numerical libraries.

The object of the SSI project is the development of basic libraries
for large scale scientific simulations which have been developed
separately in each field, and its integration into a scalable software
infrastructure. The components include a scalable iterative solvers
library Lis, having a number of solvers, preconditioners, and matrix
storage formats that are flexibly combinable, a fast Fourier transform
library FFTSS for various superscalar architectures with SIMD
instructions, which outperforms some vendor-provided FFT libraries,
and a language- and computing environment-independent matrix
computation framework SILC.  The latest version of the SSI Libraries
can be downloaded from the following URL:

Supported Features
==================

* Lis
  1) Fast quadruple precision implementation using SIMD instructions, 
     combined with mixed-precision iterative solvers
  2) Various preconditioners, including parallel algebraic multigrid 
     and user-defined preconditioners
  3) Support for various architectures, including IBM Blue Gene, Cray XT3, 
     and the Earth Simulator (beta)

* FFTSS
  1) Extremely high performance FFT kernels on various superscalar 
     architectures, including Intel Itanium 2, IBM POWER, and PowerPC 
     for Blue Gene systems
  2) Parallel multidimensional transforms

* SILC
  1) Distributed parallel matrix computation with mathematical expressions   
  2) Support for BLAS and LAPACK, in addition to original libraries 
     including Lis and FFTSS
  3) Win32 binary package for trial use
