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

[Mats Kronberg]

Dear Neolith and Kappa users,

This is just a reminder that Kappa and Neolith will be unavailable
tomorrow from 08:00.


Also, if you want to run short jobs, today is a good day for that. There
will be many nodes available on Neolith and Kappa, since no long jobs
can start until after the downtime.
