an Aldor library to express parallel programs
Overview
, called pi-it, is a library for parallel
Aldor computation, currently under development at ETH Zürich. It is designed to be architecture independent
(heterogenous) and runs on network of workstations, where a workstation can be a single processor
or a multiprocessor machine (shared or distributed memory). The library is portable across different
Unix platforms and can be easily compiled on all systems that Aldor supports.
The goals of parallel computer algebra systems are:
- independence from the architecture (portability)
- efficient execution of irregular parallel programs, and
- high level programming to hide low level details, especially those associated with synchronization of parallel programs
The goals of are:
- to implement parallel features with Aldor in order to achieve high system performance;
- to define a minimum set of function ensuring portability of source code to different architecutres;
- to experiment with a programming model for parallel algorithms for computer algebra.
is based on a portability layer written in C
that provides a set of C functions (with calling convention from Aldor to C) to interface standard
libraries that mix communication (MPI, PVM) and threads (DTS,
Athapascan). Currently this interface is target
to use LAM/MPI.
