MPI: The Complete Reference
TLDR
MPI: The Complete Reference is an annotated manual for the latest 1.1 version of the standard that illuminates the more advanced and subtle features of MPI and covers such advanced issues in parallel computing and programming as true portability, deadlock, high-performance message passing, and libraries for distributed and parallel computing.

A Proposal for a Set of Parallel Basic Linear Algebra Subprograms
TLDR
The PBLAS are targeted at distributed vector-vector, matrixvector and matrix-matrix operations with the aim of simplifying the parallelization of linear algebra codes, especially when implemented on top of the sequential BLAS.

ScaLAPACK: A Portable Linear Algebra Library for Distributed Memory Computers - Design Issues and Performance
TLDR
The content and performance of ScaLAPACK, a collection of mathematical software for linear algebra computations on distributed memory computers, are outlined and alternative approaches to mathematical libraries are suggested, explaining how Sca LAPACK could be integrated into efficient and user-friendly distributed systems.

UDDIe: an extended registry for Web services
TLDR
UDDIe is implemented -an extension to UDDI, which supports the notion of "blue pages", to record user defined properties associated with a service - and to enable discovery of services based on these.
