[Ct-grid] terena certificates
by Tom Visser 04 Feb '11

04 Feb '11

Hi, Based on comments in a recent ct grid meeting i've been playing around with the terena certificates. This nice service enables members of accredited organisations to apply for a certificate while using their home instutions credential to identify themselves. I have requested a certificate en succesfully became a member of a VO. Be carefull: Changing your certificate dn would mean you will have problems accessing your previous data. https://tcs-escience-portal.terena.org/about_nren.php I have one question: are these fully qualified certificates for grid use, or are their any differences? Are their any issues we would have to reckon with? Does anybody have experiences with job-submission using a terena certificate? Thanks for your thoughts, Tom Available identity providers NIKHEF SARA SURFNET TERENA TUDELFT Universiteit Tilburg Vrije universiteit Tom Visser Phone: +31617411603 Mail: tom.visser(a)sara.nl SARA Computing & Networking Services High Performance Computing and Visualization http://www.sara.nl

[Ct-grid] CHEP talks
by Jeff Templon 05 Nov '10

05 Nov '10

Hi *, There were a number of particularly good talks at CHEP last month, I will be posting links to a few of them here. To start with : Sverre Jarp's talk on how HEP can take advantage of current trends in CPU/GPU development. http://117.103.105.177/MaKaC/materialDisplay.py?sessionId=2&materialId=4&co… Interesting to compare this with the (quite good) talk given by the Dell Dude at the conference, although the slides don't do the talk real justice. http://117.103.105.177/MaKaC/materialDisplay.py?sessionId=27&materialId=1&c… JT

FYI -------- Original Message -------- Subject: Hadoop workshop at SARA, December 7 Date: Wed, 3 Nov 2010 17:13:08 +0100 From: Evert Lammerts <Evert.Lammerts(a)sara.nl> To: Evert Lammerts <Evert.Lammerts(a)sara.nl> What: SARA Apache Hadoop computing workshop When: Tuesday, December 7th Where: SARA, Science Park 121 Amsterdam, room TBA Dear readers, You are all invited to participate in the first Apache Hadoop "hackathon" in The Netherlands on Tuesday, December 7th. This event is also the kick-off of the SARA Proof-of-Concept Hadoop service. More information on the event and the technology can be found below. If you are interested in participating, please register as soon as possible, and not later than December 1st by sending an email to evert.lammerts(a)sara.nl. Best regards, Evert Lammerts =================================================== SARA Apache Hadoop "Hackathon" Back in 2004, driven by the need to process extreme amounts of data, Google developed a system that exists of the Google File System and MapReduce. Based on two papers that Google published on the topic[1,2], Doug Cutting[3] created what is now the Apache Hadoop software stack. Apache Hadoop is used in several capacities by a number of internet giants (e.g. Yahoo!, IBM, eBay, Facebook, Last.fm, LinkedIn, Twitter and many more[4]). It's ability to store and process extremely large datasets makes it particularly beneficial for sciences as Natural Language Processing, BioInformatics, Social Sciences and Humanities. SARA provides a Proof-of-Concept Apache Hadoop storage and computing service for scientific use[5]. The "hackathon" will be a hands-on introduction to Hadoop. You are invited to come spend a day at SARA to play with the system, with the support of two experienced users, Edgar Meij (UvA) and Djoerd Hiemstra (UT). You can work on your own or in groups and analyze your own dataset or play with for example the Wikipedia, ENRON or White House access records datasets. Programming skills will be assumed, and you need to take your own laptops. Coffee and soft drinks will be provided throughout the day, and lunch will be served at 12.00 AM. Program: 09:30 - 09:35 Introduction to the day 09:35 - 10:15 Examples of data analysis with Hadoop 10:30 - 17:00 Hackathon 17:00 - end Presentation of results [1] http://labs.google.com/papers/gfs.html [2] http://labs.google.com/papers/mapreduce.html [3] http://en.wikipedia.org/wiki/Doug_Cutting [4] http://wiki.apache.org/hadoop/PoweredBy [5] http://www.sara.nl/news/recent/20101103/Hadoop_proof-of-concept.html Evert Lammerts Consultant eScience Support SARA Computing & Network Services High Performance Computing & Visualization Phone: +31 20 888 4101 Email: evert.lammerts(a)sara.nl http://www.sara.nl

[Ct-grid] PPT, EGI InSPIRE en EMI (Nikhef urenschrijvers)
by Arjen van Rijn 02 Nov '10

02 Nov '10

Beste allen, Een aantal van jullie heeft (automatisch) bericht gekregen uit het PPT-systeem, met het verzoek om je uren over de maanden mei en juni daarin te gaan bijhouden. Ik wil met zowel de projectleiding van EMI als van EGI-InSPIRE gaan afspreken, dat Nikhef de urenverantwoording levert vanuit haar eigen systeem - zoals we dat ook in het EGEE-tijdperk hebben gedaan. Ik heb daar nog geen overeenstemming over, maar ik heb goede hoop, dat dat zal lukken. Voor nu mag je dus deze reminders even negeren. Stay tuned! Groet, Arjen
