Suite du tour d'horizon des centres de calcul utlisés par le groupe, avec l'IDRIS.
L'IDRIS (Institut du développement et des ressources en informatique scientifique) est une unité de service de l'INS2I (Institut des sciences informatiques et de leurs interactions), fondée en 1993, dont l'objectif est d'accélérer les découvertes scientifiques nécessitant de très gros moyens de calcul. Pour se faire, le centre propose à la fois un accès à des ressources importantes et un service d'aide au passage à l'échelle et à l'optimisation des codes de simulation numérique. Les ressources sont utilisées par près de 420 projets scientifiques pour un total de 1000 utilisateurs environ.
This is a bi-lingual blog of the members of the ADAMIS team at Laboratoire APC and invited guests. We comment on selected papers and events exploring, or relevant to, the interface between physics, cosmology, applied math, statistics, and numerical algorithms and which we have found interesting.
The opinions expressed in this blog reflect those of their authors and neither that of the ADAMIS group as a whole nor of Laboratoire APC.

A head in the cloud(s) ?!
Always wanted to outsource your needs for intensive, time,- memory-, and disc- wise, computations ... to somebody, somewhere, "out there" ... ? Dreamed about forgetting about operating systems, compilers, quotas, queues, architectures, etc ?!

... and around the world ...
Just piggybacking on the post by Maude below ... The supercomputing landscape as in Europe as worldwide is definitely not something engraved in a stone as some may think. In the contrary at least at its cutting edge it is by far a very dynamic system with a cut-throat competition be it a race to either putting on the floor first ever Tera (not so long time ago) and, more recently, Peta flop computer, or just for an over all leadership at any given time. In a recent change two Chinese supercomputers have reached for the very first time the 1st and 3rd spot on the so-called Top500 list, which aims at ranking all the most powerful computers of the world.

Fast(er) and not furious ...
[arXiv:1010.1260, arXiv:1010.2084, & others]
Calculations of spherical harmonic transforms is a common task for all of us who deal with data distributed over a sphere. Be it a nearly spherical shape of Earth's surface for geophysicists and oceanographers, or a sky -- an apparent location of astronomical objects as seen by an Earth-bound observer -- for astronomers and astrophysicists. Doing it fast therefore matters, as clearly does doing it even faster.
