[Ct-grid] proposed dates for the remaining grid meetings 2008
by Dennis van Dok 20 Oct '08

20 Oct '08

As discussed in today's meeting, we're going to change the time, frequency and agenda of the grid meeting. The plan is as follows: 1. To have a bi-weekly meeting, starting next week, 2. on tuesdays at 11.00 a.m., 3. at Nikhef, 4. with a focus on applications. 'Operations' will be summarily discussed, as most operational issues will move to a separate meeting. The proposed dates for the remaining meetings of 2008 are: 28 October, 11 November, 25 November, 9 December. If there are no serious objections, I'll finalize these dates by end of this week. Cheers, Dennis -- D.H. van Dok :: Software Engineer :: www.nikhef.nl :: www.vl-e.nl Phone +31 20 592 50 12 :: http://www.nikhef.nl/~dennisvd/

[Ct-grid] FW: [Condor-team] Hadoop and Condor
by Sander Klous 18 Oct '08

18 Oct '08

Hi What is Hadoop exactly? Reading through the specs it doesn't look like a competitor for dCache. So, can anybody comment on the remark below: "HDFS is much better than dCache"? Thanks, Sander > Plan: > > 1) Gain experience w/ the Hadoop File System via a large > installation on the cluster in B240. > > 2) Assuming it really works according to our expectations, > investigate how to best "pseudo-daemoncore-ify" the HDFS service so > that runs under the condor_master, responds to Condor administrative > commands such as on, off, restart, reconfig, etc, and hopefully has > similar behavior for a debug log and config settings.

That's really interesting. As one datapoint: I was talking to Brian Bockelman about HDFS. He has been deployed HDFS at his OSG site in Nebraska, and thinks that it is great, much better than dCache. An interesting question, once we get far enough along with this work: can the interface to HDFS be made pluggable? That is, can Condor call out to a file transfer service? I don't know if it makes sense, but we might be able to plug in other services one day.

[Ct-grid] invitation: opening BiG Grid 'eScience in Industry' (registration has opened!)
by Vrijaldenhoven, Serge 16 Oct '08

16 Oct '08

Philips Research<http://www.research.philips.com/> (eScience Support) together with Gridforum.nl<http://gridforum.nl/> present: BiG Grid Opening at High Tech Campus Eindhoven " e S c i e n c e i n I n d u s t r y " Monday the 1st of December, Philips Research (eScience Support) is organizing a symposium themed 'eScience in Industry'. In multiple scientific fields people are struggling with handling large datasets, secure connections, large simulation times, distributed datasets etc. This asks for a new way of working and the term eScience is used to describe the kind of science that need this new way of working. The talks will show how pharma and biomolecular science have become eScience. Further, 2 speakers from eScience centres located in the United Kingdom will share their ideas on eScience. For more information please visit: http://www.hitech-projects.com/registration/event.html. Or register directly at: http://www.hitech-projects.com/registration/. Registration is free for everyone (but limited!), so make use of this invitation to register early. The symposium is held on the occasion of the opening for BiG Grid (see http://www.biggrid.nl<http://www.biggrid.nl/>) at the High Tech Campus, Eindhoven, The Netherlands. Because around that time part of Big Grid will be physically located here at the Campus and is planned to be fully operational. Gridforum Nederland is the association for everyone in The Netherlands who is interested in or works with gridtechnology - from user to supplier, from scientist to policy maker. The organization offers a platform for the exchange of knowledge, expertise and information on this technology and all possible applications it enables. eScience Support is the new name for the non-generic IT department of Philips Research ICT. It is there specifically for researchers, delivering Scientific and Engineering IT.

[Ct-grid] MPI
by Jeff Templon 15 Oct '08

15 Oct '08

Hi *, Discussion in the TCG now on these two tasks: https://savannah.cern.ch/task/?7945 https://savannah.cern.ch/task/?7995 The "EGEE MPI recommendations" do not address the problem in the first task; the TMB is looking for someone to chair a new TF to come up with a new recipe. SARA reported that they had put significant work in getting MPI running lately, perhaps they would be interested in chairing this group? Who was heading this at SARA? JT
