Hi Stu and friends,
Seismic is a totally different beastie. He probably
does not want to do that.
You have very serious performance parameters you need
to maintain. The sheer size of data I/O is mind
numbing for those not working in the field. By the
time you start with 5+TB of data, travel time data
(needed on even higher performance storage), space for
temporary files and results, the 400-1000 nodes that
will be running hard over the next 4-6 weeks... And I
just thought the procurement costs were hard. Add to
that infrastructure to support and AC, security, etc.
You have spent a couple of fortunes.
Do You Yahoo!?
