HP reflogging DataDirect storage

,----[ Quote ]
| HP already has its Ibrix and PolyServe-
| powered X9000 scale-out network-attached 
| storage (NAS) in its cluster portfolio, 
| along with its SFS G3, a product using 
| MSA2000 storage and the Lustre file 
| system, which is aimed at Linux cluster 
| HPC users. In other words, this product 
| line-up implies the X9000 isn't well-
| suited for Linux HPC cluster use.

Cray Launches the Cray XE6 Supercomputer - The Next Generation of Its High-End Supercomputers

,----[ Quote ]
| Fully upgradeable from a Cray XT5 and Cray 
| XT6 system, the Cray XE6 supercomputer 
| features additional enhancements such as 
| an improved network resiliency, a mature 
| scalable software ecosystem and the third 
| version of the Cray Linux Environment, 
| which was announced in April 2010.


Cray launches Gemini super interconnect

,----[ Quote ]
| Right now, the CCM feature of Cray Linux 
| Environment 3.0 is supported on XT6 and 
| XT6m mini variants and only emulating 
| Ethernet, but will be backported to XT5 
| and XT5m machines later this year and to 
| XT4 machines in early 2011; eventually, 
| CCM will be able to emulate InfiniBand as 
| well, if your HPC apps prefer that.



GNU/Linux Tops TOP500 Supercomputers Again

,----[ Quote ]
| The fact that GNU/Linux totally dominates the top 500 supercomputing list is
| hardly news, but the fact that it has managed to *increase* its market share
| yet further is.
| Here are the results for June 2009:
|     GNU/Linux 443 (88.6%)
|     Windows 5 (1.0%)
|     Unix 22 (4.4%)
| and here are the figures for six months ago:
|     GNU/Linux 439 (87.8%)
|     Windows 5 (1.0%)
|     Unix 23 (4.6%)


Linux shows staying power on Top500

,----[ Quote ]
| The latest list indicates growing Linux dominance. Linux is used in the top
| nine supercomputer systems in the world. When considered as the primary OS or
| part of a mixed-OS supersystem, Linux is now present in 469 of the
| supercomputer sites, 93.8% of the Top500 list.


Why is Linux THE FASTEST operating system today?

,----[ Quote ]
| Now that I mentioned supercomputers at the time of this writing the worlds
| fastest supercomputer runs Linux. In fact most of them run Linux as you will
| see here in the list of the top 500 supercomputers. Out of all of the
| operating systems on these supercomputers Linux is a whopping 87.8% with
| windows only (giggle) 1% as can be seen here. The current worlds fastest
| supercomputer runs..... Redhat Linux and Fedora. The exact same ones you can
| download and install on your personal computer.

Version: GnuPG v1.4.10 (GNU/Linux)
