[Swift-devel] MODIS freezes on Midway

[Yadu Nand]

Hi,

I think I've found the reason for the modis tests failing on beagle.
I had no default project set on beagle. The jobs go through once I've set
the
projects to :
CI-CCR000013 Michael Wilde           The Swift Parallel Scripting System

-Thanks,
Yadu
