The purpose of the experiments is too see how much throughput we can get on Teragrid using Quanta's RBUDP (Reliable Blast UDP). Two end points are NCSA teragrid cluster and SDSC teragrid cluster. Theoretically there is 30 Gbps bandwidth composed by 3 10 Gbps circuits between them. In reality there is only 20 Gbps because one 10 Gbps in San Diego side is down.

In the experiments, UDP packets use 8900 bytes because jumbo frame is enabled from end to end. In each RBUDP session, data size is 2 Gbytes (Each cluster node has 8 Gbytes memory, but I can't allocate more than 2.1 GB for some reason I don't know). Sending rate is 1 Gbps.
