Dolphin-Scali PPK - Product Information
Dolphin-Scali Parallel Processing Kit for Linux, Solaris, and NT. Codename: WulfKit

The Dolphin-Scali PPK enables construction of powerful, scalable, parallel processor systems at affordable prices.
This kit, along with user supplied Sun or Intel architecture platforms, enables construction of a scalable, MPI (Message Passing Interface) based, multiprocessing system for parallel applications -- at an affordable price. Using this proven technology ­ it is simple to construct a powerful multiprocessor system which runs MPI-based supercomputer applications yielding impressive performance benchmarks and low price/performance ratios. This performance is achieved by combining Scali's fast inter-processor communication software, and Dolphin's high speed, low latency SCI network interconnect technology. There is an informative web presentation on this architecture which may be viewed at ... http://www.scali.com/Presentation/sld001.htm

Scali Technology
Scali provides affordable, scalable, supercomputer topology ­ without compromise. Compared to traditional parallel systems -- Scali systems offer an order of magnitude better price/performance for parallel applications. These systems are based on standard SUN or Intel architecture processors, Scali MPI, Scali processor-interconnect software, and high performance, low latency, Dolphin SCI network interconnect technology. Scali computer systems are scalable to hundreds of processors through the use of an innovative Dolphin SCI torus topology with a distributed interconnect scheme that eliminates the need for expensive centralized switches and provides improved operation and reliability at significantly lower cost.


Dolphin Technology
Since 1992 Dolphin has offered a comprehensive line of very high speed computer interconnection equipment using IEEE Standard 1596 SCI (Scalable Coherent Interface) interconnect components. This product line continues to grow in numbers and increase in performance with no limits into the foreseeable future. Dolphin's product line includes: (1) Network Interface Cards, (2) Cables, (3) Switches, (4) Integrated Circuits and (5) a large selection of software to enable these products to be used with a number of popular computers and operating systems. Dolphin also licenses some of its IC and circuit designs to selected customers. Customers include OEMs (computer equipment manufacturers), VARs (Value Added Resellers), and end users of computer equipment. These legendary products are found where lightning fast and reliable data movement is needed for computers and computer peripherals. This includes parallel supercomputers, modern file servers, clustered computer systems, I/O equipment, and high-bandwidth network connections. To visualize just how fast Dolphin's SCI interconnect technology is ­ one may contrast it with, for example, the ubiquitous Ethernet standard. Fast Ethernet runs at a maximum signaling rate of 100-million bits per second, while Dolphin's SCI technology operates at 8-billion bits per second.

Scali MPI
Scali's MPI is a native, very high performance implementation of MPI which features multi-thread safety, command line replication to all involved nodes and simultaneous inter-node and intra-node MPI communication. The MPI runs with multithreaded drivers for interfacing to the low level hardware and OS functions. The Scali MPI follows MPI 1.1 specifications and has been tested against a large number of test suites to assure compatibility with the specifications and error free operation. The Scali MPI software comes complete with all the required drivers for the PCI to SCI adapter cards and provides the following: n n n n n n n n n n Highly optimized implementation High Bandwidth ­ Low Latency Multi­thread safety - with flexible thread dialect Simultaneous inter/intra node operation Exact message size option MPI 1.1 verified through 1665 MPI testing Fault tolerant operation Automatic selection of physical transport mechanism Unix, NT and Linux command line replication Built-in support for the EtnusTotalView Debugger: www.etnus.com

Applications
A major application for this combination of products is Parallel Computing. A fine example of this is the 96-node, 192-processor, torus connected cluster operating at the Center for Parallel Processing in the University of Paderborn in Germany. http://www.uni-paderborn.de/pc2/systems/sci/psc1/index.htm The Dolphin-Scali Parallel Processor kit gives researchers and developers the opportunity to build high performance and cost effective clustered systems for SPARC or INTEL based SMP (Symmetrical MultiProcessing) nodes The result is a stable MPI enabled hardware and software ensemble for any supercomputing research project. This setup is also applicable for research or OEM adaptation in the areas of scalable routers and storage networks.
