Dolphin PCI Express Software
Dolphin offers a variety of software application for the PCI Express interconnects. This software takes advantage of the advanced features of PCI Express to deliver superior application performance. The Dolphin SuperSockets API accelerates Berkeley compliant sockets applications without the need for application changes. The SISCI Developer’s Kit maximizes the performance of application using the PCI Express hardware. It delivers the lowest latency and highest throughput for application performance.
Dolphin SuperSockets
Dolphin SuperSockets delivers a fast and transparent way for any networked applications to dramatically improve performance. In combination with Dolphin Express hardware, application implemented with a sockets interface can take advantage of extremely low latency and high bandwidth. SuperSockets is a Berkeley API compliant sockets interface that allows low overhead TCP/UDP/IP sockets to use Dolphin Express hardware.
This page describes the Linux version. Consult these pages for SuperSockets on Windows.
The software is highly optimized to reduce system load (e.g. system interrupts) and uses both PIO and RDMA operations to implement most efficient transfers for all message sizes.
The major benefits are plug and play, high bandwidth, high availability, and much lower socket latency than network technologies like 10G Ethernet, 1G Ethernet, Infiniband and Myrinet. Dolphin SuperSockets uses Dolphin Express Hardware remote memory access to implement a fast and reliable connection. An overview of the technology can be found in the Dolphin SuperSockets brochure.

Dolphin SISCI Developers Kit
The Dolphin SISCI Developers kit (Software Infrastructure Shared-Memory Cluster Interconnect) consists of driver and API software, tools, documentation and source needed to develop your own embedded application utilizing the low latency and high performance of a Dolphin PCI Express Cluster. The development kit provides a C system call interface to ease customer integration to the PCI Express cluster interconnect. SISCI enables customer application to easily bypass the limitations of traditional network solutions, avoiding time consuming operating system calls, and network protocol software overhead.
Superiour performance
Using the latest Dolphin PCI Express IX technology SISCI applications directly benefit from remote access time down to 0.74 microseconds and more than 3000 Mega bytes / second throughput. Direct mapped NTB access gives extremely low transaction overhead and jitter for real-time systems.
Typical applications for SISCI
Migrating to the powerful SISCI environment after is easy. The following application benefited from the move to the SISCI API:
·         Low latency, low jitter realtime simulators
·         Bus bridging PCIe-PCI-PMC-cPCI-XMC-VME-PXI
·         Remote access to IO Systems
·         Direct device to device transfers
·         Reflective memory functionality
·         High Availability servers / Fast fail over
·         Fat pipes / low latency messaging
