Communication Library for Linear Algebra

Basic Linear Algebra Communication Subroutines

Purpose of the BLACS:

• A design tool, they are a conceptual aid in design and coding.
• Associate widely recognized mnemonic names with communication operations, improve program readability and the self-documenting quality of code.
• Promote efficiency by identifying frequently-occurring operations of linear algebra which can be optimized on various computers.
• Program portability is improved through standardization of kernels without giving up efficiency since optimized versions will be available.
