Plans for Christmas 2006

Compilation of Responses from LHC Experiments

ALICE

We would like to continue running. Regards,

Federico Carminati

ATLAS

Dear all,

ATLAS is planning to run productions over the Christmas - New Year period. We appreciate the lack of attempts at improving services and the associated stability we usually get during this period.

In addition, there will surely be people who submit their own Grid jobs to the system, as is happening already now.

We do not ask for a special level of support, but we are happy with a "best effort" support level.

Cheers, Dario

CMS

Hi Kors,

CMS does not require centers to be up over the christmas break. A "best effort" is ok for people running analysis on hosted data, and we may make "opportunistic" use of whatever center is available over Christmas to run some MC production.

Cheers, LatB

LHCb

Hi Kors

Just to clarify last year we had a successful production over the Christmas period but we took the services "as is" We are not expecting anything different from sites this year.

Cheers, Nick

Compilation of Responses from Sites

ASGC

Taiwan will be running during the Christmas and New Year. Whether the service level will be reduced depending on request. However, we will have problem during the Chinese New Year. There usually will not have people on duty but the machines and some services will still be running. Of course, that may also depend on request.

Best, Simon

BNL

The BNL Tier 1 expects to be up and fully operational through the Christmas / New Year period. Response to problems may be somewhat slower than usual on the actual Holidays themselves.

Bruce

CERN

I think that it is very important that we make the effort to run over this Christmas, agreeing up front what the service level is (even if "best effort" or "unattended").

We have rather few Christmases left before data and we have surely learnt during the SC programme that unless you try something it is pretty unlikely to work as you expect.

I don't think it is realistic to let everyone decide for themselves.

We should agree clear service goals, measure them and have a post-mortem in January.

IMHO, of course.

Merry Christmas!


Jamie

CNAF

Dear *, INFN T1 will be up and running during the Christmas period with a slightly reduced level of support. Anyway, we will guarantee emergency interventions for hw and sw problems.

FNAL

Fermilab is starting a major electrical upgrade of the building that houses the USCMS condor worker nodes, and also starting a significant cooling system maintenance effort in the building that houses the USCMS storage nodes.

Due to this needed work, USCMS Tier1 Facilities will be unavailable:

Worker Nodes: Noon on Wed Dec 14 to 8 AM on Tue Dec 27 Storage Nodes: 7 AM on Sat Dec 17 to Noon on Sun Dec 18

These times were chosen after a long careful study to minimize the impact on CMS and on the Run2 experiments at FNAL. We apologize for the lengthy downtime, but it is needed to extend the infrastructure capabilities so we can continue to ramp the USCMS facility to the required beginning of experiment capacities.

Jon Bakken

PS: For the service challenge, this means that transfers can continue except for Dec 17-18. Grid jobs will not be accepted between Dec 14 to Dec 27 because the workers will be powered off.

GRIDKA

GridKa will run unattended from December 24 till January 2. However some team members will monitor status and email during this period on a voluntary basis. Problems will be looked after but it will take longer time before they get fixed.

This information is also avalailable on our Service Challenge Web Site at

IN2P3

Hi,

CC-IN2P3 will be up and running during the week between Christmas and New Year.

Cheers,

Dominique

NDGF

NIKHEF/SARA

Hi *,

NIKHEF will be up and running over Christmas as well. We won't be looking at the site as frequently as during normal non-vacation times, but we will respond to problems, ie we will do what we did last year. As you can see from the link

rrdg-running-year-lhc.png

we were essentially full for the holiday period with no significant interruption of service.

JT

PIC

Hello,

PIC will be up and running during the christmas time. Operator support will be provided during working days (all but 26-Dec and 6-Jan) and on working hours.

cheers, Gonzalo

RAL

RAL will run unattended from Saturday 24th December until Monday 2nd January inclusive. During that time staff may informally look in from time to time - and may resolve easy to fix major problems, however the presumtion should be that if a RAL service has gone down over XMAS it may not be back up until 3rd January.

Regards Andrew

TRIUMF

Hi Kors,

TRIUMF will keep the services up & running at a reduced level of support. We should be able to check the system remotely once a day, so expect at least 24 hours response time during that period for problems related to software, hardware failures will take longer to fix.

Bye Reda

GRIF

Jamie,

I don't know if you plan to put information on T2 in your Christmas Plans page. If this is the case, GRIF will be running during Xmas. During the week between Xmas and New Year, there will be only offsite operation support (but this should not make any big difference).

Michel

GSI

Dear Jamie,

GSI will also be running during the Christmas time. We will supervise the processes from $HOME smile via remote login etc.

Cheers,

Kilian
