SuperSockets provides 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 with absolutely no modifications.
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.
Key Product Features
- All applications will benefit from Dolphin Express without modification
- 100% compliant with Linux Socket library, Berkeley Socket compliant
- No OS patches or application modifications required. Just install and run
- Supports multiple adapters per host for increased fault tolerance and speed

- Field prooven for various MPI libraries, MySQL, DRBD and Oracle RAC
Low latency - Sockets
Real benchmarks shows that a complete 1 byte socket send - socket receive is completed in 1.99us (Full round-trip in 3.98us). As far as we know, this is a new world record and appr. 10x times better than regular Gigabit Ethernet.
High Througput - Socket
Benchmarks using iperf shows more than 21000 megabit/s throughput using standard TCP_STREAM sockets over one single IXH adapter card running in PCI Express x8 Gen2 configuration.
SuperSockets is available for all popular Linux 2.6 - 3.x distributions and kernels for Intel and AMD x86 and x64 systems (32 and 64 bit installations).
All software are provided as rpm or deb packages for Linux. An installation scrip enables automatic cluster wide installation on all nodes. More details can be found in the download and installation guides section.
