GLOBE Claritas Processing on Demand

One of the most powerful computers in the Southern Hemisphere is taking GLOBE Claritas’ seismic processing capability into a new realm. GNS has teamed up with the New Zealand Supercomputing Centre (NZSC) to boost the speed and versatility of the GNS-developed GLOBE Claritas seismic processing system, and to offer seismic processing “on demand”; a first for New Zealand.

The Wellington-based NZSC is made up of 1008 Intel 2.8 Gigahertz Xeon processors on 504 IBM dual Blade servers. Each of the processors is equivalent to a modern desktop machine, but they can be tasked to work together in groups on a single computational problem.

The NZSC offers a processing on demand service, and this, combined with the versatility and power of GLOBE Claritas makes it an incredibly economical seismic data processing solution. Trials with new GLOBE Claritas 3D migrations were run with 28 CPUs have produced encouraging results. A processing job that took four hours on a GNS desktop computer was completed in ten minutes – 24 times faster than normal.

Running a CPU-intensive sequence on 20 processors was 17 times faster than running on a single processor. Even taking into account the time required to distribute the executable and data across the cluster, this is an almost linear speed up, relative to the number of processors used.
