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, GAMESS, 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 (n
1/2
) 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 ad-
ditional CPU cores are added to a system, dramatically reducing application run times.
Other less effective interconnects can become a performance bottleneck, 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

Features
The InfiniPath InfiniBand adapter delivers industry-leading per-
formance 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.
