Overview Technical Specifications More Information   QLogic Single Port 10Gb InfiniBand to PCI Express HCA (QLE7140-CK)   Key Features: QLE7140 Host Channel Adapter The InfiniPath InfiniBand adapter delivers industry-leading performance in a cluster interconnect, allowing organizations to gain maximum advantage and return from their investment in clustered systems. The InfiniPath adapter yields the lowest latency, the highest message rate and highest effective bandwidth of any cluster interconnect available. As a result, organizations relying on clustered systems for critical computing tasks will experience a significant increase in productivity. New applications being developed or deployed on very large clusters now can avoid the bandwidth, latency, or message-rate limitations imposed by traditional interconnects. By allowing you to drive up the utilization of your computing infrastructure, InfiniPath adapters increase the ROI of your computing assets. Superior Application Performance The InfiniPath adapter’s low latency and high message rates result in superior real-world application scalability across nearly all modeling and simulation applications. Well-known applications that have demonstrated superior scaling and outstanding performance when running on clusters with the InfiniPath interconnect include: NAMD, Amber8, PETSc, Star-CD, Fluent, NWChem, DL_POLY, LS-DYNA, WRF, POP, MM5, LAMMPS, GAMES, CPMD, AM2, CHARMM, GROMACS and many others. Highest Effective Bandwidth and Message Rate Because of its high messaging rate, the InfiniPath bandwidth curve rises faster than any other adapter. The InfiniPath PCI Express adapter delivers significantly more bandwidth at message sizes typical of real-world HPC applications and many enterprise applications. The InfiniPath InfiniBand adapter also delivers the highest effective bandwidth of any cluster interconnect because it achieves half its peak bandwidth (n1/2) 2 at a message size of just 385 bytes, the lowest in the industry. This means that applications run faster on the InfiniPath adapter than on any other interconnect. Such superior performance is a benefit of the unique, highly-pipelined, cutthrough design that initiates a new message much faster than competitive alternatives. This approach allows application message transmission to scale close to linearly when additional CPU cores are added to a system, dramatically reducing application run times. Other less effective interconnects can become a performance ottleneck, lowering the return on investment of your computing resources. Lowest MPI & TCP Latency The InfiniPath industry-leading MPI pingpong latency of 1.6 microseconds2 (μs) is less than half of the latency of other InfiniBand adapters. Unlike other interconnects, its random-ring latency for up to 256 CPUs, as measured by the HPC Challenge Benchmark Suite, is nearly identical to its ping-pong latency, even as you increase the number of nodes. The InfiniPath adapter, using a standard Linux distribution, also achieves the lowest TCP/IP latency and outstanding bandwidth.3 Eliminating the excess latency found in traditional interconnects reduces communications wait time and allows processors to spend more time computing, which results in applications that run faster and scale higher. Built on Industry Standards The InfiniPath adapter supports a rich combination of open standards to achieve industry-leading performance. The InfiniPath OpenIB software stack has been proven to be the highest performance implementation of the OpenIB Verbs layer, which yields both superior latency and bandwidth compared to other InfiniBand alternatives.
