Therefore, a number of distributed-memory parallel systems (also known as multicomputers) have been built with a k-ary n-cube forming the underlying topology, such as the Cray T3D[11], the J-machine [12], the iWarp [13], and the IBM Blue Gene [14].
TCP promises to open the market for NVMe over fabrics by leveraging the native Ethernet transport, without requiring the deployment of network protocols such as data center bridging (DCB), iWARP or RoCE.
New standards such as iWARP and RoCE also support RDMA allowing data centers to utilize RDMA with reasonable cost.
Chelsio T6 100GbE adapters also offer the industry's lowest RDMA over Ethernet (iWARP) latency at 1.2 micro-second user-space to user-space, with true kernel bypass, zero copy, and processing fully offloaded to the server adapter resulting in very low CPU utilization.
The Terminator 4 represents Chelsio's fourth generation TCP offload (TOE) design, third generation iSCSI design, and second generation iWARP RDMA implementation.
With its unique ability to fully offload TCP, iSCSI and iWARP protocols on a single chip, Chelsio's adapter cards unburden communications responsibilities and processing overhead from servers and storage systems, resulting in a dramatic increase in application performance.
In combination with support for iWARP, iSCSI, TOE, and forthcoming Mac OS X and Solaris drivers, Chelsio is providing a complete solution for the media industry.
MVAPICH/MVAPICH2 is being used by more than 535 organizations world-wide to extract the potential of InfiniBand, iWARP and other RDMA-enabled interconnect networking technologies for designing high-end computing systems and servers.
An emerging suite of technologies, including MX, RDMA, iWARP and hardware-based transmission control protocol (TCP) offload, are focused on reducing the latency and improving the overall efficiency of 10GbE endpoints.
* 10 GbE continues to benefit from emerging Ethernet advancements, such as hardware-based iWARP support (RDMA over TCP/IP) that further optimizes performance and reduce CPU utilization.
Recent high-performance architectures (nCUBE-2 [Hwang 1993], iWarp [Hwang 1993], and Intel Paragon [Quinn 1994]) employ wormhole routing in which the header flit of a message establishes the path, intermediate flits follow the path, and the tail flit releases the path.
This architecture has been implemented for the iWarp distributed-memory system and has been used by a number of applications.
