A study was made of conceptional construction problems and implementation features of parallel libraries executed on various firmware platforms, supporting the most frequently used programming languages and implementing the most general and effective methods for solving sets of equations for a wide range of application problems. The performance data, features and state of the libraries implemented at the moment are given. The perspectives of practical application and development for a given work are considered. The work implemented under four-sided agreement between Lawrence Livermore National Laboratory (LLNL), Intel Inc., Mississippi State University (MSU) and RFNC-VNIIEF on the “Parallel mathematical libraries” project is presented.

The requirements are imposed on construction of successive and parallel BLASP library, resulted from a program model for parallel solution of M(t) x = u(t) equation. The methods for matrix disribution to processes and exchange schemes are studied. The obtained performance is presented.
