Cray and atsec Achieve CC Security Certification of Cray Linux Environment
Evaluation by atsec information security Confirms the Operating Systems on the Cray XT4 and Cray XT5 Supercomputer Products Meet the Stringent Security Demands of Government and Defense Customers
January 29, 2009: 07:30 AM ET
Cray Inc. (NASDAQ: CRAY) and atsec information security announced today that the Cray Linux Environment (CLE) has been certified by the National Information Assurance Partnership's (NIAP) Common Criteria Evaluation and Validation Scheme as conformant to EAL3+ (enhanced with Flaw Remediation ALC_FLR.1). This evaluation took into consideration a number of new functionalities: the Lustre network file system, Portals high-speed Remote DMA and the application placement scheduler ALPS. The evaluation covers Cray Linux Environment 2.1 running on the Cray XT4 and Cray XT5 computer systems.
This evaluation adds to atsec's impressive record of timely completions of Linux OS evaluations. Since August 2003, atsec has initiated and completed more than 15 Linux evaluations at EAL3+ and EAL4+ on a broad range of hardware platforms. In order to help its customers reach their markets effectively and take the maximum benefit from their evaluation investment, atsec aims at completion of CC projects in conjunction with the company's development schedules.
"The CC certification of CLE continues a long history of Cray support for demanding government and defense computing requirements," said Ian Miller, Cray senior vice president of sales and marketing. "The Linux-based operating system within the CLE suite is designed to run large, complex applications and scale efficiently to more than 240,000 processor cores. CLE provides a rich, highly efficient programming environment that makes it easier to develop scalable applications using the MPI, SHMEM, UPC and OpenMP parallel programming models."
atsec performed the first-ever CC evaluation of a Linux OS in 2003. This evaluation was further proof that the Common Criteria standard is flexible enough to adapt to a variety of software paradigms.
Stephan Mueller, Lead Evaluator for atsec, notes, "Considering the distributed nature of the operating system, the testing was a challenge which was handled efficiently."
Only a handful of companies worldwide are accredited to perform evaluations under more than one national scheme. atsec's Common Criteria labs have been accredited by NIAP CCEVS in the U.S., BSI in Germany and CSEC in Sweden to perform evaluations. This international presence and a large staff of qualified evaluators enable atsec to offer its customers both maximum flexibility and proven expertise and experience in Common Criteria evaluations.
The new i7 chips have HT, I was hoping that it was gone for good!
As for all this supercomputer stuff going on here.
How big is the market for these things?
Windows will soon scale enough to be able to capture over 85% of the enterprise market for servers.
If people need to go bigger, they can easily migrate to Windows HPC.
"Yup, HT creates logical processors"
It is actaully confusing because there is a trend away from HyperThreading. However I know in a Hypervisor, captured CPU's are referred to as logical processors and there term logical and cores are often interchanged, but I think it came from HyperThreading which used to really help.
1 CPU < 1 Hyperthreaded CPU (2x) < 2 Cores in performance because while a Hyperthreaded CPU allows for very fast context changes, it still only Shas 1 execution unit and can only execute one thread at time. 2 Cores can execute 2 threads at a time.
I don't think the final API is out, so you may be correct in calling them logical processors in the end.
A current high end process Xeon 7400 has 6 cores and no Hyperthreading. So a 4 processor system ends up having 24 cores. It is interesting to note that the Itanium already scales up to 512 processors. However I hope to never have debug another Itanium program! Some things are just not meant for humans.
Linux is too customisable and has so many features it scares most users. I'm a GNU/LINUX user and advocate, but some of my friends are so scared of LINUX because they hate change. I'm trying my best to ease them into it, after all LINUX VIXTA looks just like Vista and you can use the LINUX XP for the xp look. I've also been trying to convince some gamers to stick with the PS3 for games but they insist on winXP and PCgaming.

"This is why is matters.. Linux 87.8% of supercomputers. Windows 5%"
Two years ago it was Linux on over 90% and Windows on zero. The real reason Linux get used is cheap college labor.
Why don't you ask Cray?
Actually the article isn't about how high it scales, it's about security certification by atsec. Another area where Microsoft notoriously sucks. I just thought it was interesting that the article mentions, in passing, how Linux leaves Microsoft in the dust WRT scaling. Nobody is sitting around waiting for Microsoft to catch up, they just go ahead and do what they need to have done while Microsoft eats their dust.
