Subject: UPDATE: SC09 Bandwidth Challenge activity

We just received an update -- the bandwidth challenge will be on  
Wednesday evening, so tonight's reservation on Intrepid has been  
released.   There may be variability in the schedule depending on when  
each participant finishes their time slot, so we plan to leave  
Intrepid reserved for the entire 8 PM - 12 AM CST time slot.   If the  
Argonne team finishes before midnight, we will release the reservation  
early.
