Dolphin Launches High-Speed Reflective Memory Solution
Competitive price/performance through innovative use of system memory combined with high-speed, low-latency interconnect system
Real-time simulation of complex systems like power electronic systems can require the power components to be simulated with frame times as low as 2 to 5ms. Dolphin’s reflective memory solution attacks this problem with a high-performance switched network, enabling a hardware-based data broadcast approach. Data broadcast is similar to the ring serial reflective memory networks of the past, except that data is broadcast to all server nodes simultaneously instead of serially, providing lower latency between the nodes. In real-time simulation environments latency is the single most critical element to fulfill the performance requirements. Benchmarks have shown that Dolphin’s switch-based approach has significantly reduced application latency versus other reflective memory approaches. Dolphin Express combines bandwidth of 10 Gbits per second with latency as low as 1.2 microseconds.
The new reflective memory solution from Dolphin is utilizing system memory, eliminating the need for costly SRAM on the board. This gives the ability to easily adjust the memory needed for different applications or simulations, as well as contributing to a very competitive price/performance.
The new solution is based on Dolphin Express, a high-speed computer interconnect utilizing standard PCI Express. The DXS410 switch supports up to 10 nodes connected through standard CX4 cables to a DXH510 Host Bus Adapter in each host. In addition to copper cables, optical fiber is available, supporting distances up to 300 meters between the nodes. The reflective memory solution also includes Dolphin SISCI Developers kit (Software Infrastructure for Shared-memory Cluster Interconnect) complete with drivers, API software and tools for memory configuration and general setup. Linux, Solaris and Windows are supported operating systems.
Dolphin Express with Dolphin Developers kit for reflective memory is available immediately. For further information and to order, please visit Dolphin’s web store on http://www.dolphinics.com/shop.
