Schedule for SC99 Access Grid w/ QoS demo

Mon Nov 8 13:54:22 CST 1999

This is indeed a problem.. I wasn't aware that you were multiply scheduling 
the AG display..
The problem with the globus machine is that it doesnt have all the gear 
that the AG machines
have which is what we want for the QoS demos..  For demos that are just 
using the AG display
they could easily be AG originated source material.. so I might suggest 
that you consider
using the AG in the mode too.  We were hoping to do the QoS demos a few 
times per day.. They
really need the use of the video and audio and display during that time..
