Thanks to all our visitors at HPCC in Newport and Linux/Open Source on Wall Street in NYC. We enjoyed our discussions and showing you our latest products.

Next event: NEPCON/OEM NE April 30 - May 1, Boston.

Network Performance Report!
HPC Times - April 2008

How good is your MPI?
Try MPI Link-Checker and See

In many HPC applications, a single slow node can reduce the performance of the whole cluster by 50% or more! Our free cluster network test will determine if your cluster is operating correctly. Issues detected include loose connections, poor cabling and incorrect software configurations.

  • Compile and run Microway's batch mode MPI program
    • Simple instructions - requires about 2 seconds for each node
  • Upload the output file for your free performance report
    • Network health analysis
    • Comparisons with our test clusters
    • Suggestions for improving performance

MPI Link-Checker Output
Identifies Problem Nodes

MPI Link-Checker graphically identifies network problems. Latency and bandwidth are separated, providing a detailed analysis of cluster performance.

Microway is keenly focused on providing GREEN technologies, many of which also bring side benefits:

  • WhisperStation gives you high performance for compute-intensive applications without the noise. Our new lower RPM fans and quiet, high-efficiency power supply are less power hungry, resulting in both energy efficiency and drastically reduced noise pollution.
  • Our negative pressure chassis exhausts air efficiently, providing lower internal operating temperatures. Microway's fully-populated, well-cooled compute nodes and cabinets won't compromise the longevity of your cluster.
  • During software integration and test, we insure that your new server or cluster is operating at peak performance. Even small oversights in software settings can result in significant performance losses, which waste your time and electricity.

Microway clusters are now shipping with AMD's re-designed Quad-Core Opteron processors. Utilizing four upgraded 128-bit floating point units, the Quad-Core Opteron provides significant performance improvement.

Microway Servers and WhisperStations provide up to 8 Quad-Core AMD® or up to 4 Quad-Core INTEL® CPUs. Low power CPUs, achieving the same performance in a smaller thermal envelope, are also available. New solid state drives offer lower latency, increased throughput and reduced energy consumption.

Microway is offering several new components to bring increased performance to your applications:
