Experimental Environments

The performance results presented here are measured on the PrairieFire cluster [20] where CEFT-PVFS has been implemented and installed, at the University of Nebraska-Lincoln. At the time of our experiment, the cluster had 128 computational nodes, each with two AMD Athlon MP 1600 processors, 1GByte of RAM, a Myrinet card and a 20GB IDE(ATA100) hard drive. Under the same network and system environment as CEFT-PVFS, the ttcp [21] benchmark reports a TCP bandwidth of 112 MB/s using a 1KB buffer with $46\%$ CPU utilization. The disk write bandwidth is 32 MB/s when writing 2GBs of data, according to the Bonnie [22] benchmark.
