Turn off frequency scalings on your chip so that you can get reliable timings. This is essential to get a good ATLAS build
sudo apt-get install cpufreq-info cpuspeed cpufrequtils sysfsutils
# set each core to the "performance" governor, so that the clock frequency doesn't go down when idle
# I have 8 cores, which is why I need to do this 8 times
sudo cpufreq-selector -c 0 -g performance
Propagating 2D dynamics on the Muller potential using OpenMM. OpenMM runs the dynamics in CUDA or OpenCL, so this is pretty snappy.

Open Computing Language (OpenCL) is a language and framework for writing computationally intensive kernels that run accross heterogenious platforms, including GPUs, CPUs, and perhaps other more esoteric devices.
Intel provides an OpenCL implementation for Intel CPUs, but there's not a lot of instructions on how to get it set up. Here's what I did.
Installing Intel CPU OpenCL on Ubuntu (12.04)
Download the Intel® SDK for OpenCL* Applications XE 2013 from the Intel website, here http://software.intel.com/en-us/vcsource/tools/opencl-sdk-xe. The download is a tarball -- the one I got is called intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64.tgz
