KGPU: enabling GPU computing in Linux kernel

May 4th, 2011

KGPU is a GPU computing framework for the Linux kernel. It allows the Linux kernel to directly execute CUDA programs running on GPUs. The motivation is to augment systems with GPUs so that like user-space applications, the operating system itself can benefit from the GPU acceleration. It can also offload computationally intensive work from the CPU by enabling the GPU as an extra computing device.

The current KGPU release includes a demo task with GPU augmentation: a GPU AES cipher based eCryptfs, which is an encrypted file system on Linux. The read /write bandwidths are expected to be accelerated by a factor of 1.7 ~ 2.5 on an NVIDIA GeForce GTX 480 GPU.

The source code can be obtained from https://github.com/wbsun/kgpu, and news and release information can be found at http://code.google.com/p/kgpu/.

CfP: Innovative Parallel Computing (INPAR 2011)

April 13th, 2011

We are pleased to announce the 2011 Innovative Parallel Computing: Foundations & Applications of GPU, Manycore, and Heterogeneous Systems (InPar’11). This new conference provides a first-tier academic venue for peer-reviewed publications in the emerging fields of parallel computing, encompassing the topics of GPU computing, manycore computing, and heterogeneous computing.

InPar has dual focus on “Foundations”—the fundamental advances in parallel computing itself—and “Applications”—case studies and lessons learned from the application of commodity parallel computing in domains across science and engineering. The goal of InPar is to bring together researchers in the myriad fields being revolutionized by GPUs to share experiences, discover commonalities, and both inform and learn from the computer scientists working on the foundations of parallel computing.

Topics: InPar encourages papers involving current GPU/manycore architectures, new or emerging commodity parallel architectures (such as Intel “MIC” products), and hybrid or heterogeneous systems. Possible topics include, but are not limited to: Read the rest of this entry »

HOOMD-blue 0.9.2 release

April 6th, 2011

HOOMD-blue performs general-purpose particle dynamics simulations on a single workstation, taking advantage of NVIDIA GPUs to attain a level of performance equivalent to many cores on a fast cluster. Flexible and configurable, HOOMD-blue is currently being used for coarse-grained molecular dynamics simulations of nano-materials, glasses, and surfactants, dissipative particle dynamics simulations (DPD) of polymers, and crystallization of metals.

HOOMD-blue 0.9.2 adds many new features. Highlights include:

  • Long-ranged electrostatics via PPPM
  • Support for CUDA 3.2 and 4.0
  • New neighbor list option to exclude by particle diameter (for pair.slj)
  • New syntax to specify multiple pair coefficients at once
  • Improved documentation
  • Significant performance boosts for small simulations
  • RPM and .deb packaging for CentOS, Fedora, and Ubuntu
  • and more

HOOMD-blue 0.9.2 is available for download under an open source license. Check out the quick start tutorial to get started, or check out the full documentation to see everything it can do.

High Throughput Parallel Molecular Dynamics for GPUs

April 6th, 2011

The North Carolina Renaissance Computing Institute (RENCI) is running Amber PMEMD on the Open Science Grid, the high throughput computing (HTC) fabric used by the Large Hadron Collider (LHC). This approach is likely to be helpful to researchers with any of these challenges:

  1. Constrained by limited computing resources including access to GPGPUs
  2. Manually executing the same simulation repeatedly with different parameters
  3. Making simulations easier to understand, share, scale and re-use across compute resources

For more information see these two blog posts: High Throughput Parallel Molecular Dynamics and CUDA/Tesla Accelerated PMEMD on OSG. Contact Steve Cox (scox@renci.org) if you’d like to discuss further and determine if your application is a fit. If it is, RENCI can provide access to the grid as well as tools for executing and managing simulations.

Real-space calculation of powder diffraction patterns on graphics processing units.

March 29th, 2011

Abstract:

Diffraction, particularly of X-rays, is a powerful technique for the investigation of structure, microstructure and dynamical properties of matter. In order to link theoretical methods, like Molecular Dynamics and other atomistic approaches, and diffraction experiments we developed a new software for calculating the powder diffraction pattern of nano-sized objects on the GPUs. The software, soon to be made available under GPL license, allows the use of GPUs on different hosts for a direct (brute-force) computation of the Debye scattering equation.
