User-Level API Performance

User-level API (receiving) throughput

• Experiment configuration:
  • Myrinet API performance was measured at memory-to-memory level between two Sun SPARC 20/71 stations interconnected through an 8-port Myrinet switch.
  • ATM API performance was measured at memory-to-memory level between two Sun SPARC 20/71 stations interconnected through a 4-port FORE ASX-200 switch.
• Device driver software:
  • Myrinet 2.0c
  • FORE System ATM SBA-200 3.0.1
• Tools:
  • Myrinet API performance was measured using ATOMIC API library ( ATP-API ).
  • ATM API performance was measured using Netperf (version 2.0).
• Tabulated performance results
• High (Myrinet) user-level API throughput indicates the potentail performance improvement that user-level protocol implementation can achieve.
