CentOS cluster in Azure – Part 1

I have been working on Azure Resource Manager templates for a while. They are an interesting way to describe and deploy complex configurations in Azure. In particular, I have developed a template to deploy a CentOS 6.5 cluster. It will soon be published in the main Azure repository on github, but if you are interested…

DFS in Azure

Often we want to use Azure's scalable storage to deploy file servers. For geographically distributed infrastructures, it makes sense to establish a distributed file system (DFS) that spans across regions, both for availability and reach.  Here is a summary of the steps required to do so: Create a vnet in each desired datacenter, ideally with…

How Many Cores for the Job?

That is quite a common question. Experienced systems engineers have accumulated knowledge over the years that they distill into a few rules of thumb, e.g.: Given a certain hardware configuration, for software package A with an input size of X, on average you'll need Y cores. On Azure, the hardware configuration is known and you…

In the second post about Cloudblitz (http://cloudblitz.codeplex.com) we’ll examine how to use it to submit jobs to a deployed Azure cluster. Keep in mind that in Microsoft’s HPC scheduler implementation, jobs are just containers. They contain one or more tasks to be executed and have properties associated to them (e.g. credentials, priority). Such a container can…

Cloudblitz: A Tool to Deploy HPC Clusters in Azure

I’m happy to announce the availability of Cloudblitz, a tool (framework) to deploy HPC clusters in Azure programmatically via Powershell, then submit jobs to them via Powershell as well. You can find it at http://cloudblitz.codeplex.com The tool builds on the HPC scheduler for Azure and the Powershell commandlets for Azure to solve a common problem, i.e. provide…

Endpoints, firewalls and other annoyances

When you deploy a HPC cluster on Azure, you typically want to run some application in it besides those provided in the azure samples. Those applications may require their own ports to be opened on the internal network and endpoints to be established for both internal and external communication. There is no hpc cluster manager…
