[Bfys-physics] Fwd: SL5, SL6, glusterfs & stoomboot : request for user information
by Gerhard Raven 21 Jan '14

21 Jan '14

Dear bfys-physics members, please see below for the plan to upgrade stoomboot to SL6 — you are probably either not interested (if so, apologies for the spam), or getting this now for (at t least) the 2nd time (because if you’re interested, you’d be on the sbc-users mailing list). If you have reasons to think that the proposal below would have an unreasonable impact on your work, please respond ASAP, as no reply will be taken as (implied) consent to the proposal! Note that there already is (has been for some time already) an interactive node, stbc-isl6, which serves as a ‘preview’ of what to expect, so you can use it to verify that your workflow works (or can be adapted to) SL6. Cheers, — Gerhard Begin forwarded message: > From: Jeff Templon <templon(a)nikhef.nl> > Subject: [Stbc-users] SL5, SL6, glusterfs & stoomboot : request for user information > Date: January 21, 2014 at 12:47:21 GMT+1 > To: "stbc-users(a)nikhef.nl Stomboot MailList" <stbc-users(a)nikhef.nl> > Cc: "stbc-admin(a)nikhef.nl" <stbc-admin(a)nikhef.nl>, programmaleiders(a)nikhef.nl > > Beste Users and Program Leaders, > > [ This is a reminder to stbc-users ; programmaleiders, this was sent already on 17 january but I did not have permission to send mail to the programmaleiders list.

[Bfys-physics] Rehearsal talks Jamboree
by Tjeerd Ketel 14 Dec '13

14 Dec '13

Dear all, I would like to thank all speakers for their rehearsals and apologize for the short discussion time on 6 December. We decided to update the slides at Indico after the comments were integrated, but I do not know if that is done. Speakers, can you indicate behind the title of your contribution on the Bfys meeting of your rehearsal, when you updated your slides by adding: (13 Dec, updated slides) http://agenda.nikhef.nl/conferenceDisplay.py?confId=2665 http://agenda.nikhef.nl/conferenceDisplay.py?confId=2666 http://agenda.nikhef.nl/conferenceDisplay.py?confId=2685 Best regards, Tjeerd

[Bfys-physics] my Upgrade talk at the Jamboree
by Eddy Jans 13 Dec '13

13 Dec '13

Hi, I uploaded a new version to the Nikhef indico page of this morning: http://agenda.nikhef.nl/conferenceDisplay.py?confId=2685 It incorporates most of the comments made this morning and the ones that I received by email. Thanks for that. Really appreciated. I am still fighting a bit with: - the effective honest number to quote for the gain of the Upgrade with respect to continuing the old way, - I don't like slide #11 with the performance of the present VELO under Upgrade conditions, - I don't like the x-axes of the plots on slide #18, but there probably isn't an alternative. If you have suggestions/ideas/comments don't hesitate to communicate them to me. Have a good weekend and will see most of you on Monday, eddy -- ****************************************************************** *** Nikhef, P.O.
