Why Cheap HPC?
Why Cheap HPC?
Because sometimes we need to go fast(er).

Ways to get extra performance for little to no extra money.

Graphics Processing Units

GPUs are great at simple programs that are massively parallel, such as rendering images.

They can do this because they have many shaders, or “Compute Units”

Shaders can be programmed to do most things that a normal CPU can do.

448 Compute Units across 16 cores @ 1.15 Ghz
Up to 5GB DDR5
GPGPU!
This laptop’s GPU has about as much computing power as the world’s fastest supercomputer in 1993 (~91 GigaFLOPS)
GPGPU!
Special desktop computers with 4 Tesla cards can do about ~4-5 TerraFLOPS

That’s ridiculously crazy

You can probably program your GPU, and it’s just free untapped power

Problem Euler Demo
The following iterative sequence is defined for the set of positive integers:
n n/2 (n is even)n 3n + 1 (n is odd)
Using the rule above and starting with 13, we generate the following sequence:
13 40 20 10 5 16 8 4 2 1

To The Cloud! Cloud Computing
The Cloud
If you use the cloud for your site or as a datastore right now, you can acquisition temporary extra computing power very easily.
The Cloud
TalentRooster needed to re-encode all 1200 of their video resumes.
To do this locally, it would have taken about 27 hours, with 60% of that time would have been downloading and uploading.
The Cloud
The Cloud
The dev team added an extra EC2 instance, and re-encoded the videos in 3 hours.

Amazon also has instances with 2 Telsa GPUs on each instance. - Just sayin’ :)
Stealing Candy From BabiesWindows HPC Server 2008 R2
HPC Server
Instead of buying more computing power, just make idle computers do your work.
HPC Server
HPC Server 2008 R2 allows you to add Windows 7 workstations as compute nodes.
Also allows Azure instances to be added as compute nodes when you need extra horsepower.
HPC Server
About $925 for the Suite, including licenses for compute nodes.
