Performance results

We present here the communications network performance under different programming levels:

With our custom MCP: sustained Gigabit!!

Here acces to the raw Performance at the BIP level

We obtain a 1005Mbit/s bandwidth and 4.3us one-way latency.

Half of the bandwith (63Mbytes/s) is available for messages of size 4096 bytes.

IP with BIP driver

On our Pentium Pros:
ttcp reports 39Mbytes/s bandwidth for UDP, TCP is about 35Mbytes/s

One-way latency with TCP is about 70 microsecond!

More information and results with the BIP-IP driver.

IP with Myricom driver

You will find on this page some measurements with either PVM, LAM MPI or the socket API, all using the Myrinet IP driver.

Other Results

BIP/IP versus Myricom/IP: Here is table comparing the Myricom software to our driver using several interfaces.
