  K42 - Wikipedia, the free encyclopedia
K42 is an open-source research operating system currently being developed primarily at IBM TJ Watson Research Center for cache-coherent 64-bit multiprocessor systems.
K42 consists of a small exception-handling component that serves as the microkernel, a fast IPC mechanism called protected procedure call (PPC), and servers for all other components of the operating system.
K42 is the university's third generation of research on scalable operating systems.

 Experience with K42, an open-source, Linux-compatible, scalable operating-system kernel IBM Systems Journal - Find ...
K42 is an open-source, Linux **-compatible, scalable operating-system kernel whose implementation is based on advanced programming techniques and incorporates innovative mechanisms and policies.
K42 was designed to scale up to machines containing hundreds of processors, and down to machines with four processors.
In K42 we use the rich set of device drivers, file systems, and other code available with Linux, and we are active in the community that is developing core kernel technology.

 K42 key technologies
K42 is designed to run on 64-bit architectures and we have taken advantage of 64 bits to make performance gains by, for example, using large virtually sparse arrays rather than hash tables.
K42 is fully preemptable and most of the kernel data is pageable.
K42 is designed to support a simultaneous mix of time-shared, real-time, and fine-grained gang-scheduled applications.

 K42/Tornado Operating System
K42 is a research operating system currently being developed to address performance and scalability issues of system software on large-scale, shared-memory, NUMA multiprocessor computers.
The operating system is a product of research at the University of Toronto in collaboration with the K42 group at the IBM Thomas J.
K42 consists of a small exception-handling component that serves as the micro-kernel, a fast IPC mechanism, and servers for all other components of the operating system.

 K42 structure
K42 is structured around a client-server model (see Figure 2).
When writing an application to run on K42, it is possible to program to the Linux API or directly to the native K42 interfaces.
The translation of standard Linux system calls is done by intercepting glibc system calls and directing them to their K42 implementation, as described in Section 4.1.

 Running K42 at UofT
The second and third consoles are for thinwire, a low level protocol we use to speak to the K42 kernel and to connect a debugger to the kernel.
Then within the debugger, load the symbols and connect to K42 at the correct port and machine (the middle panel should display the port number on the last line).
K42 has a fast reboot mode that just reinitializes the OS without resetting the hardware or reloading the kernel from the NFS host or thinwire.

A segregated K42 wetland behind the late-Wisconsin moraine east of Sterling (polygon (21925).
These infrequent kettle map units occur segregated as concentric rings of sedge dominated plant communities (K2) surrounded by shrubbier communities with a deeper water table (K3), which are, in turn, surrounded by woodland or forest (K4).

 MrExcel Message Board :: View topic - VBA>>>>>VBA>>>>>MACRO>>>!!!!!Please Help me!!
But now the problem is it only works for one sheet, it copies the sum of the K column into k42 cell of "sheet", but if i add another sheet, it replaces the old value of the k42 cell on sheet "sheet", which means i am loosing my old data from the previous sheet.
Now it upgrades the value to cell k42 of Sheet "Sheet", but if i add another sheet based on the same template, instead of adding the values from new sheet to the old value of the k42 cell, it overwrites the value of the new sheet to cell k42.
Lets suppose i have total value of 10,000 in k42 cell after the end of one sheet, once i add another sheet (sheet2 based on that template) and start puttind data that data should be added into 10,000(old value of k42) not to be replaced.

 K42 Adventure Race Marathon - Race Details
As Cesar, the owner of Quest Patagonia (the adventure travel company which arranged my visit) told me prior to the race, “be prepared for any weather conditions; it could be 20 degrees and snowing or it could be 70 degrees and hot.”
The race and Villa are located in the eastern side of the Andes mountains just north of Bariloche.
The weather was in the low 40´s or high 30´s and a light rain fell from the sky.

The K42 approach to this IDL is to extend C++ with a small number of "decorations".
K42 not only allows OS services to be customized to the needs of an application, but also allows the customization to be changed, on-the-fly, while the service is in use.
For example, we show how K42 can switch a (per-file) page cache from a centralized implementation to one distributed across the processors of a multiprocessor in order to adapt to changing access patterns.

 BattleSpace - K42 Firehawk class VertJet
After a range of prototypes, the K42 was the first military specific version of the VertJet to be produced.
It performes much the same role as the helicopter of the 21st century but, with its extreme speed and limitless manouvreability, the Firehawk can be a powerful heavy air assault vehicle.
The Fuller LX-88 charge reactor can provide enough power for the K42 to run contnuously for 3 days before refueling is required.

 Utilizing Linux kernel components in K42   (Site not responding. Last check: 2007-09-08)
An examination of the run-time environment within the Linux-kernel is the starting point for a presentation of the strategy taken to incorporate Linux-kernel code in K42.
There are four basic aspects of this strategy; presenting K42 as an architecture target for Linux-kernel code, developing interfaces allowing K42 code to call Linux-kernel code, implementing some Linux-kernel internal interfaces using K42 facilities and selectively building Linux-kernel code to include only the desired components.
Of these four aspects the first is the most technically interesting and is the focus of most of this paper.
