[intrepid-notify] NOTICE: SC09 Bandwidth Challenge activity

[Andrew Cherry]

For a 90 minute window tonight (Tue) or tomorrow night (Wed) between 8  
PM and midnight, Intrepid and Eureka resources will be allocated for  
Bandwidth Challenge activities at SC09.  Although the login nodes will  
remain open for use, Eureka and Intrepid will be reserved to prevent  
competing activity on the filesystem.  In addition, GridFTP will be  
disabled for all users except those involved in the challenge.  We ask  
that you avoid any heavy filesystem activity on /intrepid-fs0 during  
that time, and plan any GridFTP transfers to happen outside of those  
two time windows.

Unfortunately, we still do not have an exact time slot for the  
activities, as the BWC committee has not finalized their schedule;  
hence the rather broad time windows specified above.  As soon as we  
have an exact time window from the users involved in the challenge, we  
will send an update.  The long blocking reservations bwc_block1 and  
bwc_block2 will be modified appropriately as soon as we have the  
update from the BWC folks.

During the reservation, you may not see jobs running on the system --  
this is expected, since the bandwidth challenge activity will be  
performing GridFTP transfers to our filesystems.
