Operating System Multilevel Load Balancing
White Paper Although sched domains implementation allows Linux to build a multilevel hierarchy to represent multilevel machines, the generic code of the current kernel version builds no more than two levels in the sched domains hierarchy. [10 Jul 2008]
MontaVista Software Teams with IBM to Enable Zultys Enterprise Communication System
White Paper Zultys turned to MontaVista Software as MontaVista has an excellent reputation in the Linux community and it authored the preemptible kernel patch and real-time scheduler - two Linux extensions that are very important to them. [03 Jul 2008]
Extreme High Performance Computing or Why Microkernels Suck
White Paper The suggestions frequently received say that Linux cannot scale because it is a monolithic operating system kernel. This paper gives an overview of why Linux scales and shows the hurdles microkernels would have to overcome in order to do the same. [02 Jul 2008]
Common Misconfigured HP-UX Resources
White Paper Not only do processes need memory in order to run, the HP-UX operating system (or kernel) also needs spaces for its critical resources and tables. While there are many possible system resources that can take up memory, this paper attempts to... [05 Jun 2008]
Virtualisation: IT managers warned of security challenges
News Crosby said that, in general, virtualisation reduced the number of points of entry into operating systems but that vendors relying on kernel access to implement security would run into difficulties. And Hyper-V has the full attack surface of any... [16 Apr 2008]
ACPI Driver Interface in Windows Vista
White Paper This paper documents the mechanism for executing ACPI control methods and handling events from a kernel driver in the Windows Vista operating system. Kernel-mode device drivers are able to evaluate ACPI control methods via I/O ConTroL Codes (IOCTLs). [28 Mar 2008]
Cheat Sheet: Google Android
Cheat Sheet In Google's words, it's a "complete software stack" for mobile phones, built on an open Linux kernel (Linux version 2.6) - so that's an operating system plus all the middleware and key apps you need to drive a mobile phone. [12 Mar 2008]
OEM Utilizes Windows Embedded to Speed Development of Personal Navigation Device
White Paper The company evaluated open source platforms but had concerns about finding kernel engineers in time. Instead, Mobile Crossing chose Microsoft Windows CE 5.0 for its powerful embedded OS development tools, rich native and managed application tools... [04 Mar 2008]
Implementing Solaris Zones With Veritas Cluster Server by Symantec
White Paper From an implementation view, a local zone does not instantiate a separate operating system kernel as is done with virtual machines; instead zones operate as resource "Containers. From an application view, the zone appears to be an independent... [29 Feb 2008]
A Measurement Study of the Linux TCP/IP Stack Performance and Scalability on SMP Systems
White Paper It was found that although raw CPU costs are not very different between the two kernels, Linux 2.6 shows vastly improved scalability, attributed to better scheduling and kernel locking mechanisms. The performance of the protocol stack... [19 Dec 2007]
TCP Congestion Control Over 3G Communication Systems: An Experimental Evaluation of New Reno, BIC and Westwood+
White Paper This paper focuses on the UMTS wireless scenario and it reports a campaign of measurements that involved around 3000 flows and more than 40 hours of measurements using three different TCP stacks: TCP NewReno, which is the congestion control... [19 Dec 2007]
Vista - business uptake still slow
News Vista 64-bit security features, such as Kernel Patch Protection, which blocks attempts to modify the core OS, would not be effective against certain types of malware, Marcus warned. One reason businesses have not been keen to upgrade to Vista is... [20 Nov 2007]
