Playing with NFS & GlusterFS on Amazon cc1.4xlarge EC2 instance types
Early single-client tests of shared ephemeral storage via NFS and parallel GlusterFS We here at BioTeam have been kicking tires and generally exploring around the edges of the new Amazon cc1.4xlarge “compute cluster” EC2 instance types. Much of our experimentation has been centered around simplistic benchmarking techniques as a way of slowly zeroing in on [...]
Exploring the new AWS Compute Cluster EC2 Instances
Note: Depending on how you found this post, it might be helpful to understand our own personal & professional biases. We are bioinformatics and HPC types specializing in life sciences, not people trying to build the next twitter or facebook. What we care about when it comes to AWS performance may not be what YOU [...]
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 [...]
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 [...]
Instead of spending 20 minutes to format an ext3 volume every time you need one, you could just snapshot a ...
Let me add a few remarks about Ext3 as well.
The reason we usually recommend Ext3 instead of XFS is because ...
I'm using these slides to tune SGE 6.2 @ European Space Agency, thanks a lot! 
Great post.
Can you also try our native scale out NFS protocol? Next 3.1 release of Gluster will include it ...
So far my mental architecture is shaping up to be something like this:
Use the ephemeral disks for scratch space and ...
This shows that on-demand HPC still has a ways to go, it is very unfortunate that only ext3 is supported ...
We have had sge62u3 working fine in a 10.5 cluster using cron to startup the sge_execd process on clients. Trying ...
Instead of increasing your disk image size, you could have decreased the memory by writing a very short C program ...
