Previous: Experimental Results on Write
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 
CPU utilization. The disk write bandwidth is 32 MB/s
when writing 2GBs of data, according to the Bonnie [22]
benchmark.
