First, I want to thank many people for enriching my summer. Second, I would like to announce the Clobi project on Google Code. Continue reading

new system successfully tested: “Distribution of High Performance Computing Jobs among Multiple Computing Clouds”

Hello you out there!

I just started running the first serious test of the system I’ve developed during this year’s Google Summer of Code. If I wanted to put it in sensational words, the test could be called “Distribution of Particle Physics High Performance Computing Jobs among Multiple Computing Clouds”; just to get some readers :-). During the test, there will be some time I just sit around and watch my monitor, so I decided to share my experience about the new system with you and keep record of the test progress within this blog post.

CernVM: local ATLAS Software — the clean solution

In my blog post CernVM: how to set up a local ATLAS Software Release, I presented a brutal approach how to override CVMFS (CernVM‘s filesystem with HTTP backend) to install a local ATLAS Software release. Now I worked out a very clean and smooth solution. This approach allows:

  • to use the local ATLAS Software without “hacking” anything
  • to use local software and software provided by CVMFS at the same time.

EC2: Install ATLAS Software to an EBS volume

In CernVM: local ATLAS Software — the clean solution I proposed to install an ATLAS Software release to an EBS volume. I did it to make it locally available in CernVM running on EC2. The approach allows to move an EBS volume from one EC2 instance to another without losing important components and functionality. Here are some hints (both, CernVM specific and general) to follow before installing the software via pacman. Continue reading
