Back in Canada for my second 3PGCIC conference – this time as coorganizer. A long flight followed by a small one and a taxi ride – I just managed to arrive in time to present my paper on REStful web services for distributed computing.
It was a short stay, but I took a walk around downtown Victoria, saw a few … Read the rest
This post is a reflection on the DeIC conference I attended in November 2012.
Before taking off for Canada I just had time to attend the first day of the DeIC conference (scroll down for English) here in Denmark. Here‘s a summary of the plenary talks (sorry – Danish only).
The conference marked the initiation of the … Read the rest
When I saw this, I knew we’d have to to arrange some babysitting for the 19/10:
My old hero coming to Copenhagen.
Chris was in top shape.
“Look Kenny, I’m the Queen!”

The first trip in my new role as cloud technologist of DeIC went to Oslo – for the Nordunet 2012 conference – my second one of the kind. These conferences are primarily a meeting ground for the Nordic NRENs to meet with each other and a few of the other major NRENs like SURFnet, and AARNet … Read the rest
It started as an elephant…
Thor dual-container POD.
My second visit to Iceland – for the Nordunet Conference.
Very fittingly, mostly a networking event – and an excellent one.
This time I didn’t even have time for the Blue Lagoon – but I had time to visit the Thor Datacenter.
Our second son was born 27th of November 2011.
A small miracle he is
Back in Barcelona to present a paper at 3PGCIC-2011 – a well organized and pleasant conference with a varied program. Good discussions on distributed computing. Excellent social arrangements including the reception banquet at the charming Institut d’Estudis Catalans and a visit to the Mare Nostrum supercomputer of the BSC – located in a former chapel.

My first ACAT conference – this year hosted by Brunel University. I presented a paper on my GUI for ATLAS data processing.
The topics of ACAT match very well what I’ve been doing both during my PhD days and alter – and I’ve been wanting to go for years, but never managed till now. Of course it’s … Read the rest
Recently I’ve stumbled upon the terms citizen science and citizen cyberscience. The last term was apparently invented by Shuttleworth Fellow Francois Grey as a label for BOINC-based distributed computing projects like seti@home, folding@home and his own lhc@home. Grey is also behind the Citizen Cyberscience Centre in Geneva – on the web pages of which there’s more information to be … Read the rest
As exemplified on the pictures above (from the photo gallery of one of the students), CERN School of Computing includes a good deal of extracurricular activities. Which probably goes a long way in explaining the good and humorous atmosphere in the classroom.
Having spent a lot of energy preparing the exercise with the great CSC team, it really was great … Read the rest
In this post I’ll try to explain the vision behind a software suite I wrote at the Niels Bohr Institute, University of Copenhagen, 2009-11.
The ideas for the software arose from my dual involvement with the high energy physics and the e-science groups. Some of the code originated in previous projects, including distributed computing efforts of the ATLAS experiment at … Read the rest
Came across this CD by chance. The soloist – living here on Østerbro, is the grandson of the composer .
Post-romantic, austerity, suspense and longing. Apparently it appeals to the younger generations

I’m quite happy with my small HTPC running Boxee on Ubuntu. The hardware is a Zotac Ion board with an Atom CPU and an Nvidia graphics card. Both software and hardware have their issues, but after enough hacking I’ve a setup that gets the job done wrt. watching movies off my file server. My main gripe has been the lack … Read the rest
In this exercise we’ll solve the same assignment as in exercise 1, but using a prepackaged GridPilot application.
- Download and install GridPilot
- Start GridPilot and answer the initial questions – enable only the computing system “GridFactory” and set the submission host to gridfactory.nbi.dk
- Import the app “ttbar_exercise”
- Select the application/dataset “ttbar_exercise-100k-events” and click “Run”
- Select the application/dataset “ttbar_exercise-merge” and

Since November 2010 we’re living on Østerbro – and very happy with the neighborhood. Kindergarten, shopping, swimming, karate, fitness and cafe’s all very close and very children friendly.
Here’s a picture of spring coming to our backyard:
This is a follow-up post to my previous post “Front door locks”.
I’m happy to announce a little utility that exports TCS certificate/keys to the hard disk – more precisely to your “.globus” directory where grid tools expect to find them.
Here follows instructions on how to use it:
First, you of course need to have some TCS credentials … Read the rest
When my family and I recently moved into our new apartment, it was equipped with a front door with two locks: both of them with a spring latch. To get in, we needed to put a key in each and turn both while somehow turning the door handle at the same time. It could take quite a while … Read the rest
The original purpose of GridPilot was to make it easy for researchers to run, preserve, rerun, share computations on the emerging national and international grid infrastructures. The word infrastructure is used in plural here – indicating our failure to create the grid. Thus GridPilot was born with a pluggable backend support.
Eventually, I created my own take at a grid … Read the rest
