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.

“What’s faster–a supercomputer or EC2?” A reconsideration…
In his blog, Ian Foster recently presented What’s faster — a supercomputer or EC2?. Continue reading
Counting stuff in Python and assembling a histogram: analyze thread communication via os.pipe()
These days I built up an inter-thread communication via os.pipe()
. While one thread is only writing to the “write end” of the pipe, the other thread is only reading from the “read end”. Continue reading
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.
