A guest lecture for Computer Science students on “whatever I want to talk about”
Prior to joining Bioteam, I worked with a computational biology group at the University of Minnesota. A friend from that time is now teaching a course in Bioinformatics in the Computer Science department at St. Thomas University. He offered the opportunity to deliver a guest lecture on “whatever I wanted to talk about.”

Boot, ephemeral & EBS storage performance on amazon cc1.4xlarge instance types
Backstory For background and summary writeups of all the various blog posts we have dealing with the new Amazon EC2 “compute cluster” cc1.4xlarge instance types please refer to this summary page: http://www.bioteam.net/2010/07/19/exploring-the-new-aws-compute-cluster-ec2-instances/? Related post We talked about the performance of the boot and ephemeral storage in this post: http://www.bioteam.net/2010/07/19/local-storage-performance-of-aws-cluster-compute-instances/? This post In this post I’ve finally collected [...]

Local storage performance of AWS cluster compute instances
Lots more data collected over the weekend as we were finally able to run bonnie++ against the local boot disk as well as single and striped versions of the ephermeral storage volumes that come along with every cc1.4xlarge instance type. Key Results: Performance of the root/boot disk is way slower than any other type of [...]

How to resize an Amazon EC2 AMI when boot disk is on EBS
Note Screwing around with the boot volume is part of our regular “explore around the edges” work before we get serious with how we are going to configure and orchestrate the new systems. The boot volume in this scenario does not have PV driver support and thus will perform slower than the actual ephemeral storage. [...]

Preliminary EBS performance on Amazon Compute Cluster cc1.4xlarge instance types
Post Update History: July 13th – Original post July 14th – More results from cc1.4xlarge single-disk & initial results from c1.xlarge instance type, uploaded new version of the raw data spreadsheet to Google Docs. Updated all graphs. July 19th – Lots more data (including ephemeral storage) added to the raw data spreadsheet on Google Docs [...]

Cluster building
With all of Bioteam’s talk about cloud computing, I was a bit surprised to find myself building an honest-to-goodness non-cloud, non-virtual compute cluster a couple of weeks ago. There were wires, blinking lights, whirring fans, circuit breakers, and all sorts of messy real-world details to contend with. The servers were heavy and unwieldy, and I [...]
