Titan Oak Ridge National Laboratory

Question: Discuss about the Titan for Oak Ridge National Laboratory. Answer: Introduction The assignment focuses on 20-Petaflop Cray XK7 at Oak Ridge National Laboratory which achieves the mission U.S department of energy and security. The mission is achieved with the help of 20-petaopCray XK7 system, which is named Titan. The essay discusses various applications, architecture, software system as well as programming system of Titan. Discussion Titan is a hybrid Cray XK7 system, which is one of the most capable third generation computers which are an up gradation of Jaguar system. It is the first company of the world with multipetaflop system for deploying different types of heterogeneous compute nodes. Its architecture of constitutes of accelerator and processor, design of the node, interconnect and sstorage system. It is analyzed that Accelerator and Processor uses AMD Opteron 6274 Interlagos 16-core processor. Titan also constitutes software system which consists of Operating System, file system, System administration and Scheduler. The operating system that used is HPC-optimized Linux environment which helps in proper administrating the system. The model that is used is all message passing interface (MPI) helps in representing a paradigm shift in various types of programming as well as hardware models. The shared file system is totally dependent on Lusture, DDN as well as InfiniBand and the OLFC is committed for developing various types of tools that helps the researchers in managing results. It is analyzed that visualization is created for helping the researchers in understanding various types of data visualization technique. Conclusion It can be concluded that OLFC plays an important role in delivering the most important resources. It has provided very much powerful mashie for supporting the mission effectively. It is analyzed that the applications of the system constitute more than 50% of the workload of the system of Jaguar. The assignment provides number of other applications which are very much advantageous.
