Intel stretches HPC dev tools across chubby clusters

SC11 Supercomputing hardware and software vendors are getting impatient for the SC11 supercomputing conference in Seattle, which kicks off next week. More than a few have jumped the gun with product announcements this week, including chipmaker Intel.

No, Intel is not going to launch its "Sandy Bridge-EP" Xeon E5 processors, which are expected early next year. But the new Cluster Studio XE toolset for HPC customers will help those lucky few HPC and cloud shops that have been able to get systems this year to squeeze more performance out of their Xeon E5 clusters.

The Cluster Studio XE stack includes a slew of Intel tools for creating, tuning, and monitoring parallel applications running on x86-based parallel clusters. Intel had already been selling a set of application tools called Cluster Studio, which bundled up the chip giant's C, C++, and Fortran compilers, its rendition of the message passing interface (MPI) messaging protocol that allows server nodes to share work, and various math and multithreading libraries to goose the performance of applications.

With the XE (Extended Edition) of the HPC cluster tools, Intel is goosing the performance of the MPI library, and claims its MPI 4.0.3 stack is anywhere from 3.3 to 6.5 times as fast as the OpenMPI 1.5.4 and MVAPICH2 1.6 MPI stacks from the open source community. Benchmark tests were done on a 64-node system running 768 processes and linked by InfiniBand switches.

Intel tested the Platform Computing MPI 8.1.1 stack against the three MPI stacks listed above, only this time on an eight-mode system; in this case the performance differences between Intel and Platform (which is now owned by IBM) were not huge. With the Microsoft MPI 3.2 stack on the same iron, the Intel MPI stack running on Windows servers was anywhere from 2.17 to 2.74 times faster than the Microsoft MPI.

Flash and other storage-class memory (SCM) technologies can revolutionize the data center and cloud computing but they have significant performance, reliability, and serviceability problems. These problems compound in large-scale deployments of SSDs, requiring a cohesive Tier-0 framework for a systematic build-out. Virident Systems products solve these problems.

Games That Matter

One such popular defense tool is a virtual world game called Boarders Ahoy!. Developed by NATO's Allied Command Transformation, the training simulator prepares sailors for boarding a ship as part of a military inspection process. Users can practice interviewing the crew of the virtual ship, checking identification and locating the game's 250 searchable objects.

The United States Secret Service is also leveraging the training power of virtual worlds to prepare for national threats. "Tiny Town" is a small-scale model in use for the last four decades, which helps officials plan for such emergencies as chemical threats and enemy attacks. The model now has a 3D computer-generated counterpart, called Virtual Tiny Town. The software's advanced modeling cabilities can realistically simulate a variety of possible real-life threats, such as chemical, biological or radiological attacks, armed assaults, or suicide bombers. Planned upgrades will enhance the program's life-saving measures by adding health impacts and crowd behaviors to the model.

Academic institutions are also contributing to the arsenal of public safety measures. The recently-launched Center for Advanced Modeling in the Social, Behavioral and Health Sciences at Johns Hopkins University specializes in agent-based simulation, which predicts how individuals will react in emergency situations. The center draws from diverse disciplines, such as public safety, sociology, economics and supercomputing, to fine-tune its virtual model.
