Greetings, Two new mathematical software libraries are available on seaborg and mcurie: FFTW: ----- FFTW is a portable, free, high performance FFT library which implements arbitrary radix, serial and multiple dimensional transforms in serial or parallel (MPI and POSIX threads models). One unique aspect of FFTW is its optional use of self-optimizing strategies, whereby subsequent calls become faster by building on previous timings. Wrapper functions provide a Fortran API to this native C library. For more information see: http://hpcf.nersc.gov/software/libs/math/fft/fftw/ Metis/ParMetis: --------------- Metis is a library and application suite for efficient partitioning of graphs and other manipulation of meshes and graphs. Graph partitioning is important in load balancing and communication optimization in parallel calculations which use unstructured grids or large sparse matrices. ParMetis implements the same functionality in parallel using MPI. For more information see: http://hpcf.nersc.gov/software/libs/math/metis/ David Skinner
