As scientific computing, transaction processing requirements of the continuous improvement of computer performance, SMP system is widely applied, the scale is also growing, but because of the traditional SMP systems, all processors share the system bus, so when dealing with The number of devices increases, the system bus to increase competition in the conflict, the system bus will become a bottleneck, so the current number of CPU SMP system typically only a few dozen, scalability was extremely restricted. NUMA SMP systems technology effectively combines the MPP system easy to program and easy to extend the characteristics of SMP system solves the scalability problem, has become the mainstream of high-performance server architecture of one. Now famous server manufacturers have introduced performance-based NUMA-based servers, such as HP, Superdome, SGI De Altix 3000, IBM De x440, NEC De TX7, AMD De Opteron and so on. Linux on the server platform with the performance of more mature, Linux kernel support for NUMA architectures become more perfect, especially starting from 2.5, Linux in the scheduler, memory management, user-level API and other aspects of a large number of NUMA optimization, which currently part of the work is constantly improving, such as the recently introduced kernel 2.6.7-RC1 added NUMA scheduler. This article from the storage management, scheduler and CpuMemSets discuss three aspects.
According to Microsoft, the flaw is not through the standard DNS port ] ] TCP / UDP 53 is being used. RPC interface is usually tied to a network port between 1024-5000. According to SANS Internet Storm Center said it would reduce the risk of attack. However, the problem is still very serious. Web hosting companies usually run on a single server with different network services. The DNS flaw does not affect Windows XP or Windows Vista, but Windows 2000 Server SP4, Windows Server 2003 SP1, Windows Server 2003 SP2 will be affected. Adobe on Monday released four versions of the new generation design and Web applications. Adobe Creative Suite 3 in the PowerPC and Intel-based Mac, and Windows XP and Vista PC run, a total of 4 versions ] ] Adobe Creative Suite 3 Design Premium and Design Standard, and Adobe Creative Suite 3 Web Premium and Web Standard.
