IBM scores with Linux clusters

Both CGG and WesternGeco have turned to IBM for its ‘xSeries’ Linux-based clusters, to be used in compute-intensive seismic imaging.

CGG is to equip its Redhill (UK) and Massy (France) sites with 512 (1024 processors) and 128 (256 processors) IBM xSeries Servers running Linux. The new machines will boost CGG’s global computing power five-fold and leverage CGG’s proprietary TIKIM (Time Kirchhoff Migration) technology.


Christophe Barnini, VP Marketing with CGG said, “IBM’s Intel-based servers running Linux offer a highly attractive price/performance ratio for geophysical applications. This computing power enables CGG to deliver its strategic results far more quickly and at a highly competitive cost.” French IT consultants Adequat helped out with the Linux port.


In a separate announcement, WesternGeco will deploy a 256 node (512 processor) xSeries machine. Trevor Gatus, Houston land processing manager with WesternGeco said, “With substantially better price performance, we are able to complete jobs that once took eight weeks in three, increasing our turnaround time by a factor of two.”


xSeries-based Linux clusters are scalable from 4 to 1024 processors and have been adapted to meet the high performance needs of the petroleum market. Linked by a fast network, the clusters can be managed from a single point of control and act as either a single machine or a multiple node system. Other IBM-Linux customers include Chevron and Shell whose 1024 xSeries server, is claimed as the largest Linux supercomputer in the world.
