The Virtues of Virtualization [22753]
Benefits for HPC Implementations

Following on his talk "HPC Trends and Virtualization," a presentation given at Sun's HPC Consortium in Hamburg recently, Josh Simons goes further with his blog post "Virtualization for HPC: The Heterogeneity Issue," a subject to which he takes an even-handed approach, conceding at the outset that " ... while heterogeneity is either desirable or to be avoided, depending on your viewpoint, virtualization can help in either case."

Sun HPC Solution Ushers in Teraflop-scale Applications for Brazilian Computing Grid [22704]
Sun Blade Servers, Lustre Provide Affordable, Scalable Solution to Handle Complex Simulations

High-performance computing (HPC) initiative Petroleo Brasileiro (BR) Network was created to handle computer simulations to aid oil production in Brazil's pre-salt basin. An HPC grid was required to handle the complex project with the goal being a high-performance, affordable solution that could expand easily over the next few years. Sun, IBM, Dell, Bull, SGI, and HP were consulted. After an extensive review process, the group decided that Sun would best meet its goals for performance, scalability, energy efficiency, and cost, the latter of which was 30% less than an offering from the closest competing vendor.

"Sun Business Ready HPC for Altair RADIOSS" [22583]
An Assessment of the Cluster Approach to HPC

In his Sun BluePrints paper, "Sun Business Ready HPC for Altair RADIOSS: Best Practices for Altair RADIOSS Deployments," Dr. Gunter Roeth, of Sun ISV Engineering provides insight into constructing an optimal configuration for Altair RADIOSS car crash simulations using a high-performance cluster of Sun systems equipped with x86/x64 processors. The paper points out how HPC solutions often consist of servers equipped with Intel Xeon or AMD Opteron processors that are clustered together using high-speed, low-latency interconnects. In many cases, Roeth writes, these high-performance clusters can match and even surpass the throughput capabilities of vertically-scalable proprietary solutions.

Configuring Sun Ops Center for the Sun HPC Software Framework [22586]
Simplify the Process of Deploying and Managing Large-scale Linux HPC Clusters

Anyone interested in an integrated open-source software solution for Linux-based high-performance computing (HPC) clusters running on Sun hardware may want to read the Sun BluePrints article "Using Sun Ops Center with Sun HPC Software, Linux 2.0." Authors Mike Berg and Zhiqi Tao describe how to set up a Sun Ops Center server, provision the HPC cluster nodes (head node, Luster file system servers, and compute nodes), and configure system services.
