TotalView CUDA

CUDA introduces developers to a number of new concepts (such as kernels, streams, warps, and explicitly multilevel memory) that are not encountered in serial or other parallel programming paradigms. Visibility into these elements is critical for troubleshooting and tuning applications that make use of CUDA. This paper will highlight CUDA concepts implemented in CUDA 3.0 - 4.0, the impact of those concepts for troubleshooting CUDA, and how TotalView helps users deal with these new CUDA-specific constructs. CUDA is frequently used alongside MPI parallelism and host-side multicore and multithread parallelism. The TotalView parallel debugger provides developers with an integrated view of all three levels of parallelism within a single debugging session.

Transitioning to multicore: Part II

Multicore systems are ubiquitous; it’s virtually impossible to buy even commodity computers without a dual, quad, or hex-core processor. It won’t be long before many-core processors start to be prevalent as well. Each core in a multicore processor is capable of executing a program, so a quad-core processor can run four separate programs at the same time. That’s great if you have many different programs you need to run at one time, but can become a problem when you need performance from a single program. Those four cores can also potentially run one program faster than a single core processor would, but only if the program is written correctly. If you run a sequential (or serial) program written for single core architectures on a multicore platform, it will generally only be able to leverage a single core. Serial programs don’t run any faster, and may even run slightly slower, on multicore processors.

Many integrated core debugging

Intel® Xeon® Phi™ coprocessors present an exciting opportunity for HPC developers to take advantage of many-core processor technology. Since the Intel Xeon Phi coprocessor shares many architectural features and much of the development tool chain with multicore Intel Xeon processors, it is generally fairly easy to migrate a program to the Intel Xeon Phi coprocessor. However, to fully leverage the Intel Xeon Phi coprocessor, a new level of parallelism needs to be expressed which may require significantly rethinking algorithms. Scientists need tools that support debugging and optimizing hybrid MPI/OpenMP parallel applications that may have dozens or even hundreds of threads per node.

Validating C++ translations of MATLAB models with TotalView

This paper describes one of the many ways that developers have been able to use TotalView to enable the development of cutting edge applications. Frequently, applications in HPC are developed in stages. Problem domains such as signal processing and data analysis, applied physics modeling (geophysics, meteorology, astrophysics, computational chemistry), digital content creation, and financial analysis each have highly specialized computational challenges that call on the skills of domain specialists with deep experience in the subject matter. The algorithms, computational kernels, and other modules written by these domain specialists often are integrated together by software engineers and computational scientists who are specialists in areas like modern software component architectures, parallelism, and embedded development. This division of labor sets the stage for the creation of sophisticated applications that no single developer could have written.
