MODIS Data Processing (Russia). Disregard before September (rearranged machines w/o updating Ganglia) NASA throttles data at 2Mb/order. We peak at 6Mbytes/s, visual average for “running times”: 3 Mbytes/sec I2 gave us 12Mbytes/sec sustained (potential for 4x improvement)

MODIS Data Processing (Russia) • Disregard before September (rearranged machines w/o updating Ganglia) • NASA throttles data at 2Mb/order. • We peak at 6Mbytes/s, visual average for “running times”: 3 Mbytes/sec • I2 gave us 12Mbytes/sec sustained (potential for 4x improvement) • The last six months’ work could have been done in 1.5 months using I2.
Nominal MODIS figures (Russia) • 1 year of data ≈ 22000 granules ≈ 3.96 Tb • 1 year @ 12 Mb/sec ≈ 346,030 s ≈ 4 days • Currently, 1 year ≈ 1 month ≈ 22 work days • Potential improvement : 5.5 x
