Ping-pong latency and uni-directional bandwidth are based on the Ohio state University Ping-pong latency test.

measurement was done with a single processor node communicating to a single processor node through a single level of switch

tCP/IP bandwidth and latency are based on using Netperf and a standard Linux tCP/IP software stack.
Note: actual performance measurements may differ from the data published in this document. all current performance data is available at www.pathscale.com/infinipath.php
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 ap-
plications that run faster and scale higher.
Lowest CPU Utilization.
the InfiniPath connectionless environment eliminates
overhead that wastes valuable CPU cycles. It provides reliable data transmis-
sion without the vast resources required by connection-oriented adapters,
thus increasing the efficiency of your clustered systems.
Built On Industry standards.
the InfiniPath adapter supports a rich com-
bination of open standards to achieve industry-leading performance. the
InfiniPath OpenIB software stack has been proven to be the highest perfor-
mance implementation of the OpenIB Verbs layer, which yields both superior
latency and bandwidth compared to other InfiniBand alternatives.
