HI-UX/MPP for SR8000

HI-UX/MPP for SR8000 is a micro kernel based operating system, optimized for parallel distributed processing. It delivers high performance and reliable, flexible, operation while complying with relevant international and industrial standards. These include X11R6, Motif 1.2 and NFS version 3.

	64-bit addressing The large numerical problems to be solved require high capacity memory for efficient processing. 64-bit addressing allows both this and dramatically larger capacity file systems to be implemented. To ease migration from previous systems, 32-bit codes can be executed.
	Single system To enable easy system use and administration, the SR8000 Series presents a single system. Remote operation is possible over a network.
	Scalability HI-UX/MPP for SR8000 is designed for efficient scaling over the wide range of SR8000 Series configurations. Starting at 4 nodes (32 GFLOPS), with growth possible to 512 nodes (7.3 TFLOPS), a system can be configured to match increasing processing needs.
	SR8000 Series management functions Centre operation management is aided by functions including, amongst others, resource allocation, usage control and accounting. Unattended automatic operation is possible. Security features, including role based system administration, and backup/archiving function by ADSM^*client are provided.

Languages

Optimizing compilers for FORTRAN 77, FORTRAN 90, C, C++, Kuck and Associates C++ and Parallel FORTRAN are all supported on these SR8000 Series. Parallel FORTRAN translates HPF into FORTRAN90 before compilation. (Parallel FORTRAN translates programs of HPF into FORTRAN90 program.) These optimizing compilers all support automatic code intra-node parallelization, for execution on the multiple microprocessors within each node. In addition, automatic pseudo vectorization is supported to get maximum microprocessor performance. Cross compilers on Hitachi workstation are also available. Kuck and Associates C++ based on ISO/IEC 14882-1998 provides optimizing function for SR8000 Series.

Parallelization support and development environment

	MPI-2 The SR8000 Series supports the MPI-2 (issued July 1997) communications library for parallel program codes, an extension of the original Message Passing Interface (MPI). MPI-2 builds on MPI with the addition of features such as parallel input/output and dynamic process generation. High speed data communication is achieved by the use of the SR8000 Series' remote DMA to transfer data directly between user address spaces.
	PVM The Parallel Virtual Machine (PVM) environment is supported by the SR8000 Series for developing parallel message passing codes. The SR8000 Series' PVM, realizes high speed data communication by the use of the SR8000 Series' remote DMA to transfer data directly between user address spaces.
	Application Program Development Environment A support environment for the development, execution, and tuning the performance of application codes is provided on the SR8000 Series.
	Parallel Debugger Parallel debugger is a symbolic debugger for both serial and parallel codes.

Matrix calculation libraries

MATRIX/MPP

This library provides optimized routines.

		Basic array operations.
		Eigenvalues and eigenvectors.
		Direct methods for linear systems.
		Iterative methods for linear systems with large scale sparse coefficient matrix.
		Fast Fourier transforms.
		Pseudo-random numbers.

MATRIX/MPP/SSS

This library is a high performance library of sparse solver for linear systems with large scale sparse matrices. This type of equation often appears in the field of structure analysis. As with MATRIX/MPP, this library is optimized for the SR8000 Series. This library provides the following optimized routines.

		Skyline method.
		Sparse direct solver.

Common interface
The SR8000 Series' matrix libraries have identical interfaces to the equivalent Hitachi libraries for the S-3000 vector supercomputers, the SR2201 parallel processors and 3050 series workstations. Porting is achieved by a simple recompilation.
