Basic Linear Algebra Comm. Subprograms - Shared libs. for LAM
The BLACS project is an ongoing investigation whose purpose is to create a linear algebra oriented message passing interface that may be implemented efficiently and uniformly across a large range of distributed memory platforms. You can choose between an implementation based on MPI or PVM. This package uses MPI. The package is available for LAM and MPICH. This package uses LAM. There are packages for the shared libraries (this one), for the static libraries and the development files and for test programs. Most users do not need to install this package directly because it is used as a high level driver for the communication in the ScaLAPACK packages. Therefore, it is installed when installing ScaLAPACK. ScaLAPACK is a parallel version of LAPACK and is used on Beowulf type clusters.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
