[Neolith-users] Neolith and Kappa downtime 2010-06-22 08:00-18:00 CEST

[Mats Kronberg]

Dear Neolith and Kappa users,

On Tuesday June 22nd (2010-06-22) Neolith and Kappa will have planned
downtime from 08:00 CEST.

We have scheduled the whole day for this, but will of course try to
keep the actual downtime as short as possible.

Both clusters including the login nodes will be unavailable during the
downtime.


The scheduled work consists of upgrades to the Kappa Infiniband
interconnect firmware and software, as well as operating system
upgrades on both Kappa and Neolith.

Jobs that cannot finish before the downtime will remain queued until
the downtime is over.

Hint: short jobs will find it easier then usual to run in the days
immediately before downtime, as they don't have to compete with longer
jobs.


Kind regards,

Mats Kronberg <support at nsc.liu.se>
