Application of cluster computing for seismic imaging in the energy industry Exploration for oil and gas has been increasing dramatically in the deepwater, ultra-deepwater and shelf region of the Gulf of Mexico and other regions around the world (for example North Sea in Europe). A key technology component that helps to identify possible hydrocarbon targets as well as reduce the risks associated with such deep water exploration is seismic imaging. Seismic imaging helps to accurately position, define and delineate prospective complex subsurface structures before the dollar intensive drilling operations start. The average cost of drilling a well in the Gulf of Mexico is in the range of $50 million. Thus there is a huge emphasis on using seismic imaging to accurately define the shape of these complex subsurface structures and define the velocity variations in the surrounding regime before drilling operations commence. |

Cluster Administration Management Node A management node can be used to access the consoles of all of the cluster nodes and to monitor their status.� This is particularly useful (even necessary) in the event that a node loses network connectivity or if a node stops responding altogether. |

Cluster Interconnects                   The network fabric connecting the compute nodes in a cluster to carry inter-node message traffic is referred to as cluster interconnect or simply interconnect. The term System Area Network(SAN) is also sometimes used to denote a cluster interconnect. Although the scope of SANs is somewhat broader than cluster interconnects. Note that an interconnect does not hook up to the user LAN. It is completely under the administrative domain of the cluster administrator. The LAN administrator need not be even aware of the type of interconnect being used in a cluster, unless of course the same person is playing both roles. The user connectivity of the cluster is simply through a LAN connection on the head node of the cluster and does not require much design consideration. |

Introduction to Clusters                "Cluster" is an ambiguous term in computer industry. Depending on the vendor and specific contexts, a cluster may refer to wide a variety of environments. In general a cluster refers to a set of computer systems connected together. For the purposes of this book a cluster is set of computers which are connected to each other, and are physically located close to each other, in order to solve problems more efficiently. These types of clusters are also referred to as High Performance Computing (HPC) clusters, or simply Compute clusters. |
