Nvidia GPU

Farmshare has GPU's via two systems, rye01 and rye02. You can use these two systems as you would a corn system:

ssh rye01.stanford.edu

or

ssh rye02.stanford.edu

hardware and software

rye01 and rye02 are Intel CPU systems with following config:

rye01:

• 8 core (2x E5620) cpu
• 48GB ram
• 250GB local disk
• 6x C2070
• Ubuntu 13.10
• CUDA 6.0

rye02:

• 8 core (2x E5620) cpu
• 48GB ram
• 250GB local disk
• 8x GTX 480
• Ubuntu 14.04
• CUDA 7.0

FarmShare would like to extend special thanks to Jon Pilat, Brian Tempero and Margot Gerritsen for their support.

software

Cuda is installed along with the toolkit samples (in /usr/local/cuda)

example 1

An easy first thing to try is to login, load the cudasamples module and run deviceQuery to see what kind of cuda device it is. Then we run a matrix multiply sample that comes with the cuda toolkit.

example 2 - smokeParticles cuda sample program

• login to rye01 or rye02
• run FarmVNC
• module load cuda cudasamples
• cd /usr/local/cuda/samples/bin/x86_64/linux/release
• smokeParticles

example 3 - matlab

We can also login, load the cuda module and run the same deviceQuery and matrix multiply sample in matlab

it has its own page, click MatlabGPUDemo1

example 4 - R

Example of using cuda enabled R library to do Hierarchical Linear Regressions

example 5 - PyMOL

• login to rye02.stanford.edu
• start a VNC session as described in FarmVNC
• from the menu search pymol and then click on it
• from file menu open /farmshare/software/examples/pymol/4GD3.pdb
• click the box to full-size the model and then press the down arrow to start the animation
• I also clicked the (from upper right) S -> surface to draw the surface version (it shows up better here)
