Birmingham

I started the 24 hour read/write with RALPP on Tue 11 Oct just before 1400.

The result of the read test is:

Date of Submission was 11/10/2006
 Total number of FTS submissions = 19
 1637/1900 transferred in 86332.8145201 seconds
 1.6384210176e+12bytes transferred.
Average Bandwidth:151.82370937Mb/s

The estimated average rate of the write test is 155Mb/s. The file transfer script (version 0.5.2-1) reported a wrong date and hence a wrong average rate:

Date of Submission was 1/1/1970
 Total number of FTS submissions = 23
 1639/2300 transferred in 1160571575.93 seconds
 1.639e+12bytes transferred.
Average Bandwidth:0.0112978813818Mb/s

The ganglia plot above shows that the rates in the BHAM->RALPP direction were considerably lower (50% reduction) in this test than in the uni-directional test while the difference between the rates of the write tests was not as significant.

The load on the DPM SE waw quite high (between 20 and 50) throughout the test, possibly high enough to cause two SFT RM tests to timeout.
