Remote Sensing Processing on GPUs
Posted on 5-9-2011 by Zhenyu Ye Tags: GPU, vision

There is a recent paper on using GPUs for remote sensing processing, titled Remote Sensing Processing: From Multicore to GPU. It is using the open-source Orfeo Toolbox (OTB). A GPU implementation of the OTB is also available.

GPU mini-supercomputer starter kit
Posted on 30-8-2011 by Cedric Nugteren Tags: GPU, CUDA, supercomputing

In the CUDA newsletter, there was a small announcement about a pre-build GPU mini-supercomputer. It contains 24 GPUs, a little more than our system with ‘only’ 16 GPUs:

The new GPU Starter Kit from HP is a pre-configured system that provides researchers with a ready-to-use GPU computing cluster, straight out of the box. It combines eight HP ProLiant SL390 G7 servers (containing 24 Tesla M2070 GPUs) with 16 CPUs. It is pre-configured with CUDA 4.0.

Skeleton programming at ParCo 2011 in Ghent
Posted on 24-8-2011 by Cedric Nugteren Tags: GPU, conference, algorithmic skeletons

In the upcoming ParCo 2011 conference in Ghent, there will be a special session on skeleton programming (scroll down to the bottom – session B11).

It includes two interesting presentations related to GPUs:

  • “Flexible runtime support for efficient skeleton programming on hybrid systems”, which is part of the SkePU skeleton library.
  • “Data Parallel Skeletons for GPU Clusters and Multi-GPU Systems”, which is an extension of the Munster skeleton library Muesli.
SnuCL: An OpenCL Framework and Unified Programming Model for Heterogeneous CPU/GPU Clusters
Posted on 22-7-2011 by Zhenyu Ye Tags: GPU, tool, compiler, OpenCL

SnuCL, developed in Seoul National University, has made part of its source code public. It relies on the SNU-Samsung OpenCL compiler, which is delivered only in binary format. It will hold a tutorial in PACT 2011.

Note: It may take 10 minutes to download the package. The download speed is limited to 200KB/sec. The package size is 116MB.

Multi2Sim has recently released a GPU simulator for AMD GPUs, capable of simulating OpenCL programs. It will hold a tutorial in PACT 2011.

Intel SPMD Program Compiler
Posted on 28-6-2011 by Gert-Jan van den Braak Tags: compiler

Intel has announced ispc, the Intel SPMD Program Compiler. ispc is a new compiler for “single program, multiple data” (SPMD) programs. Under the SPMD model, the programmer writes a program that mostly appears to be a regular serial program, though the execution model is actually that a number of program instances execute in parallel.

The ispc compiler is based on the LLVM compiler and can be downloaded from

Judging by the example on their website, it looks a bit like CUDA, so it wouldn’t be too hard to get started with if you are familiar to GPU programming.
