Today Rogue Wave Software announced CodeDynamics, the next generation of dynamic analysis for data-intensive commercial applications. CodeDynamics expands the reach of multithreaded debugging from high performance computing environment into the commercial market.
In this RCE podcast, Brock Palen and Jeff Squyres discuss Conduit with Cyrus Harriston from LLNL. Conduit is an open source project from Lawrence Livermore that provides an intuitive model for describing hierarchical scientific data in C++, C, Fortran, and Python and is used for data coupling between packages in-core, serialization, and I/O tasks.
A successful example of how a well-managed GPU cluster allowed scientist to focus on obtaining results comes from the Tokyo University of Agriculture and Technology (TUAT) results. A research group lead by Dr. Akinori Yamanaka develops computation models and simulates engineering materials, for a variety of applications, using HPC. Using Bright Cluster Manager, Dr. Yamanaka and his team were able to immediately focus on algorithm development and not burden the team with cluster administration issues.
Bill Gropp presented this talk at the Argonne Training Program on Extreme-Scale Computing. “Where it is used as an alternative to MPI, OpenMP often has difficulty achieving the performance of MPI (MPI’s much-criticized requirement that the user directly manage data motion ensures that the programmer does in fact manage that memory motion, leading to improved performance). This suggests that other programming models can be productively combined with MPI as long as they complement, rather than replace, MPI.”
“We describe Oclgrind, a platform designed to enable the creation of developer tools for analysis and debugging of OpenCL programs. Oclgrind simulates how OpenCL kernels execute with respect to the OpenCL standard, adhering to the execution and memory models that it defines. A simple plugin interface allows developer tools to observe the simulation and collect execution information to provide useful analysis, or catch bugs that would be otherwise difficult to spot when running the application on a real device. We give details about the implementation of the simulator, and describe how it can be extended with plugins that provide useful developer tools. We also present several example use-cases that have already been created using this platform, motivated by real-world problems that OpenCL developers face.”
An Iceland-based “HPC in the Cloud” company called Advania has published an interesting case study with The Ubercloud, and online community and marketplace where engineers, scientists, and their service providers discover, try, and buy Computing Power and Software as a Service, from Cloud Resource and Software Providers around the world.
