Optimizing Software Applications for NUMA: Part 1 (of 7)

May 9th, 2011 · No Comments

by David Ott (Intel)
1. The Basics of NUMA
NUMA, or Non-Uniform Memory Access, is a shared memory architecture that describes the placement of main memory modules with respect to processors in a multiprocessor system. Perhaps the best way to understand NUMA is to compare it with its cousin UMA, or Uniform Memory Access.
In the UMA memory [...]

KGPU: Augmenting Linux with The GPU

May 6th, 2011 · No Comments

KGPU is a GPU computing framework for the Linux kernel. It allows Linux kernel to call CUDA programs running on GPUs directly. The motivation is to augment operating systems with GPUs so that not only userspace applications but also the operating system itself can benefit from GPU acceleration. It can also free the CPU from [...]

Making Parallelism ‘Nifty’

May 4th, 2011 · No Comments

By Dave Valentine
Getting Started with Parallelism
At SIGCSE 2009 in Chattanooga I attended an Intel presentation on Parallel Computing. The Intel representative, Michael Wrinn, said to the group, “Intel is not going back to a single core processor. The world has gone parallel and you better start teaching it!” He then wagged his finger at [...]

Mesh-particle interpolations on GPUs and multicore CPUs

May 3rd, 2011 · No Comments

Diego Rossinelli, Christian Conti and Petros Koumoutsakos, Philosophical Transactions of the Royal Society
Particle–mesh interpolations are fundamental operations for particle-in-cell codes, as implemented in vortex methods, plasma dynamics and electrostatics simulations. In these simulations, the mesh is used to solve the field equations and the gradients of the fields are used in order to advance [...]

Seventeen steps to safer C code

May 3rd, 2011 · No Comments

by Thomas Honold
In embedded systems design, many of us tend to write our software in C the way our “grandfathers” did, which was appropriate before we had to worry about ubiquitous connectivity and its security implications. Today, the programming methods of the past must be adapted to a world in which safety-critical design is [...]
