All quoted latencies
are round trip time, rack-to-rack.
While there is clearly a need to reorder outstanding commands to reduce mechanical overhead and improve input/output (I/O) latencies
, to do so goes well beyond simply collecting commands in a queue.
speed of light") latencies
, which can be greater than storage device latencies
Boasting switching latencies
that are as much as 45% faster than competitive offerings, the InfinIO 3000 is the ideal interconnect for building high performance computer clusters from groups of commodity servers.
Our testing with the MVAPICH package is showing latencies
for MPI applications of under 7 microseconds for small message sizes and bandwidths of over 850 MB/s for large messages," said Dr.
The inherent low latency capabilities of the InfiniBand architecture enable switching latencies
that are up to 30 times better than other 10Gb/sec switching technologies.
Across a single switch, average latencies
were just 400 nanoseconds.
Administrators can quickly analyze and troubleshoot latencies
so that critical line-of-business data is always available.
make this more difficult by increased jitter due to tighter buffering, thereby making coherence between the input and output significantly more difficult to achieve.
The AIOBS benchmark results show a throughput that exceeds industry average and latencies
that are well below the user-required latencies
