Abstract
The Numerical Algorithms Group Ltd has been actively involved in research and development into parallel software for many years and has contributed theoretical and practical expertise to such high-profile projects such as LAPACK. As a result of these efforts the NAG Fortran 77 Library incorporates state-of-the-art software that is efficient and portable across a wide range of scalar, vector and shared-memory computers.
A numerical library that is also efficient and portable across a range of distributed-memory machines has proven to be an elusive goal until recently. Encouraged by the promise shown by the ScaLAPACK project (a follow-on to the LAPACK project), and using the same public-domain message-passing systems (PVM and BLACS), NAG began developing a general-purpose numerical library for distributed-memory machines.
The NAG Numerical PVM Library described in this paper is of a modest size but demonstrates the concept of portable parallel software and has the potential for considerable expansion. Plans for the second release are already being implemented which will broaden the coverage and remove some limitations.
