Testing Infiniband in Rack Room
Setup
- Have 4 nodes, 16 cores each.
- Each node has one GBit and one Infiniband port.
- Infiniband switch rated at 20 Gbit/sec.
- Running IP over Infiniband, which decreases effective throughput.
- Run ET system and event producer on one node, run remote consumers on the others.
- Event producer continually reads from file and inserts events into ET system.
- Some consumers ust get events and dump them, others process the events.
- Note: when using Ethernet instead of IB got about 95% bandwidth of a Gbit link (950 Mbits/sec).
Results using Infiniband
