 C-DAC High Performance Computing and Communication (HPCC) software effectively addresses the performance and usability challenges of clusters through a high performance flexible software environment.
The HPCC software supports the development and execution of sequential, message passing and data parallel programs and allows the ensemble of workstations to be viewed as independent workstations, cluster of workstations, or as a massively parallel processor system.
The HPCC software is available on clusters with PARAMNet and supporting Solaris, Linux or AIX operating systems. A complete solution to create and execute parallel and distributed programs on UNIX clusters through high performance communication protocols, a parallel file system and a rich set of program development, system management & software engineering tools is provided.
The HPCC software suite of products includes high performance compilers, parallel debuggers, data visualisers and performance profilers. High performance communication protocols and efficient MPI implementation provide the correct framework to extract maximum performance.
The HPCC software consists of
- Base software that includes a lightweight communication substrate, optimized MPI, and a parallel file system with MPI-IO interface
- A Program Development environment, providing a rich set of FORTRAN 77 / Fortran 90 program development tools, and an integrated debugging environment for parallel programs
- System Management tools for monitoring the effective utilization of the cluster resources and for administration of large UNIX clusters
- Software engineering tools for developing high quality programs
Standards Adherence
C-DAC's HPCC software follows established standards to minimize learning time and maximize ease-of-use. Most commands use familiar UNIX syntax. HPCC software graphical user interfaces comply with Motif or Java style standards. HPCC's implementation of the MPI standard closely follows the published standard and allows programmers to write portable parallel applications which run on the PARAM systems and other cluster systems supporting the standard.
