SIEminar: "Using the IAC Chimera Cluster", by Ángel de Vicente, Wednesday 23 May 12:30

As you probably know from our previous newsletter, the IAC Beowulf cluster is now called Chimera, and it is made up of 32 bits and 64 bits (EM64T) compute machines (a total of 64 processors). When compared to the old Beoiac cluster, it also has some interesting features, like a Parallel File System (PVFS2), the Modules package to easily modify your environment, etc. The idea of this SIEminar is to briefly discuss this new environment and allow current or prospective users to find out how they can use it, and also to discuss problems or improvement suggestions that they might have regarding the cluster.

SIE's Web goes public!

The SIE's own website has moved to the external IAC Web: The SIEpedia too has been relocated on the external Web server: (we also plan to publish the Chimera Web as soon as it's ready). So our websites are now accessible from outside the IAC, thus to colleagues on travel, to collaborators from other Institutes, and to anybody looking for info on astronomical software. We have taken some safety measures:
  • Email directions are obfuscated with javascript to avoid being collected by harvesting bots.
  • Access to sensitive parts of the SINFIN site, such as internal documents, SIENews, Minutes of the (R.I.P) SIE Users Committee etc. are restricted to IAC machines through an IP-filtering php script.

Websites made in SIE

Looking back, we realize that at the SIE we have developed a good number of websites for the Research and Graduate Studies Areas. In addition to the Research, MultiMedia Service and own SIE (now external) internal pages, we built made all websites for the meetings and workshops organized by the Research Area. Our philosophy is to create simple, accesible and attractive pages using web standards. Please visit our dossier to learn more about our web development activity.

Tips for not saturating your home and mail quotas

If you think that SIE staff are so experienced and computer savvy that saturating their home or Inbox quota is an event as likely as Harry Potter showing up in the Aula in the middle of a colloquium, well, you will be disappointed. We have all passed through the shame of finding our home directory completely full, or being unable to receive mail messages because there was no space left in our mail Inbox. In our most recent SIEpedia article we offer some tips on how to check your home and email quota, and how to avoid filling them up.

Software packages upgrades

Recently, we have updated the following software packages: Bazaar to v0.15; Cloudy to v07.02; GSL to v1.9; Kile to v1.9.3; LyX to v1.4.4; WCSTools to 3.6.8; Eric3 to v3.9.4; Gifsicle to v 1.48; Grace to v5.1.28; HEAsoft to v6.2; R to v2.4.1; Specview to v1.24; Yacas to v1.0.63.
