RAL SE shutting down, do you have files there?
by Jeff Templon 20 Oct '05

20 Oct '05

Hi *, RAL (see attachment) is shutting down one of its SEs. I am not sure if the experiment collaborations have plans themselves to migrate data; if you have stored important data on this SE you may want to take action. JT

[Fwd: Accessing the Grid from your NIKHEF Linux desktop]
by Jeff Templon 17 Oct '05

17 Oct '05

Hi *, A message from Jan Just Keijser (who joined the PDP group about a month ago if you haven't met him yet): you can now access the grid services from your "normal" desktop machines, i.e. you don't have to log into ui03. A footnote (hmm, headnote?) to the included message: the minimum requirement for running this UI-on-a-desktop is that your desktop is running Scientific Linux 3, RedHat Enterprise Linux 3 or CentOS 3.x; RedHat 7.3 systems are NOT supported. This means that you can't run it from 'login.nikhef.nl': eomer:~> cat /etc/issue Red Hat Linux release 7.3 (Valhalla) Kernel \r on an \m if 'cat /etc/issue' on your machine says something like Scientific Linux CERN Release 3.0.5 (SL) then you are OK.

unscheduled downtime of NIKHEF grid systems
by Jeff Templon 04 Oct '05

04 Oct '05

Hi due to a problem with the main disk server, all of the grid services at NIKHEF (user interfaces, compute elements, and storage) are currently down. We are working on it and will let you know as soon as it is back up. Sorry for the inconvenience. JT

NIKHEF grid site back up
by Jeff Templon 15 Sep '05

15 Sep '05

Hi *, From all I can tell, everything is back up here. Not all queues are open so if you try to directly select NIKHEF to run your job, it may not work immediately; I want to wait and see how the monitoring jobs perform before opening the queues wide. Let us know if you have any problems. Jeff, Ronald, David

user interface usable for job submission
by Jeff Templon 13 Sep '05

13 Sep '05

Hi *, our CE and SE resources are not yet up, but I have just tested job submission from ui03 / tbn12 through our RB (bosheks). I was able to run a job at SARA and retrieve the output. You should be able to do the same, as long as you don't require to run at NIKHEF or get data off our CE. More info as it comes in. JT

upgrade ongoing of NPDF production facility
by Jeff Templon 13 Sep '05

13 Sep '05

Hi *, Sorry for the late announcement of this: the Grid services at NIKHEF are being upgraded right now. This means some things may not work. We are trying to get the user interface (ui03) up as soon as possible, so that you can still access the rest of the grid. We know that our storage element (tbn15 / se03) has problems right now. This was all officially registered as 'scheduled downtime' with LCG operations but apparently this does not filter down to actual users. Our estimated return to service is tomorrow morning but unfortunately we cannot guarantee this, this upgrade is a whopper. We will try not to forget the important people next time. JT

NIKHEF upgrade to LCG2.4 completed
by David Groep 29 Apr '05

29 Apr '05

Dear all, The upgrade of NIKHEF-ELPROD to LCG2.4 has completed this morning and we're seeing jobs come in again. At the same time we've increased the virtual memory available on the worker nodes to at least 4Gbyte per dual-CPU (that's 2GByte per job minimum). I hope this is sufficient for the large jobs we're seeing. If you notice anything strange, please let us know! Cheers, DavidG. PS: this upgrade also marked the permanent end of the legacy RH73 service on tbn18.nikhef.nl. All user's (including our local people) should use the "03" facility from now on. The UI is at ui03.nikhef.nl -- David Groep ** National Institute for Nuclear and High Energy Physics, PDP/Grid group ** ** Room: H1.56 Phone: +31 20 5922179, PObox 41882, NL-1009DB Amsterdam NL **
