All,
A reminder about next week's pre-GDB on batch systems. This discussion would definitely benefit from input from GridPP sites.
If you're already planning to attend & just haven't registered please could you do so.
Regards,
Ian

Subject: Re: May pre-GDB (May 12) on batch systems
Hi,
I want to give you some details on our May pre-GDB. The goal of this meeting is not to repeat again the (very good) session that we had during last HEPiX in Oxford (https://indico.cern.ch/event/346931/timetable/#20150327.detailed) but rather to have an interactive meetings where sites in the process of migrating can share their experience and their problems and get input from sites with a more advanced expertise. Sites who have not yet started to look at a Torque/MAUI alternative but are considering to do it are also welcome to participate and will certainly get a lot of useful information!
This meeting will probably focus on HTCondor experiences as this is what has been adopted by most sites in the last year. But it is by no mean restricted to HTCondor and I welcome any input from sites that used another approach/product.
I started a draft agenda: https://indico.cern.ch/event/319821/. The basic idea is that the first hour (hour and an half) of the meeting will be for very short reports from sites who are in the process of migrating (or just completed it) to identify issues to be discussed in the second part of the meeting. For this to work, I'd like any participating site who wants to report about where they are to contact me and to prepare NOT MORE than 2 slides (solution/configuration adopted, main issues). The meeting should start at 10:30 to allow people to travel in the morning and will finish between 4:40 and 5:30, depending on the level of discussion.
I'm looking forward to seeing you at the pre-GDB. Don't forget to register on the event page so that we can ensure the room is big enough...
Cheers,
Michel

Hi,
I would like to confirm that the May pre-GDB will be on batch systems and alternatives to Torque/MAUI. This pre-GDB will be co-organized with HEPiX where these topics have also been discussed.
The main goal of this meeting will be to here from different sites who moved from Torque/MAUI to something else in the last months. It seems that almost every site migrating decided to go for HTCondor but I'll be happy to hear from sites who chose something different. In addition to the batch system migration itself, the day will also cover ARC CE experiences at several (non NDGF) sites and the status of CREAM CE with HTCondor. And for every batch system we'll discuss, there will be a specific focus on multicore job support.
Agenda and details will be at https://indico.cern.ch/event/319821/. But I'll probably begin to work on it only end of April (after WLCG workshop and CHEP).
Cheers,
Michel
