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.
