ICIS recently(august 2014) acquired a new server, called Dagobert (because of its hefty price). It is a Dell R920, with quad processors (E7-4870 v2 at 2.3 Ghz) with 15 cores each (60 total) and 3 Tb RAM (1600 Mhz). A few pictures of our new server are attached. This server was bought from the Radboud Research Facilities grand to explore new research directions, achieve more relevant scientific results and cooperate with local organisations. This is the first of three phases for new equipement for ICIS. For now Dagobert is absolutely the most powerful server in our whole faculty (with a heavy 4.4 kW power supply, weight in excess of 30 kg), the next best server has only 256 Gb RAM and half the processor power.

Everybody in the department should have access now, and because no scheduling process is in place, we have to coordinate usage by ourself. I will create a

Use the mail alias ??? to which you can give notice if you require the machine for a certain time slot (e.g. article deadline, proper benchmarks with no interference of other processes). All users of the machine are requested to subscribe to this mail adres. Please let me know if you intend to use these machines, so I can add you to the mailing list.

There is accessible local storage on the device, to quickly read/write files instead of your slow network mounted home directory :

/scratch

 RAID  mirrored, but there will be NO BACKUPS of this directory. 

/scratch-striped

striped RAID volume  (faster access, less redundancy in case of hard disk crash). 
Also there will be NO BACKUPS of this directory.
