TDP, SMP, and Grid computing
Hi all,
I hope this is the right place where discuss about a possible feature of the QNX.
QNX RTOS have the TDP as a nice and useful feature to access transparently remote resources, in trusted and untrusted
environment.
Another very nice feature is the ability, through the new Advance Runtime Module (Adaptive Partiitioning), to manage
load condition and ensure CPU availability to critical process.
Now I expect that Adaptive Partiitioning works well in SMP environment moving the processes from CPU to CPU to correctly
balancing CPU usage.
In a grid computing environment, processes are moved from node to node in order to complete the assigned job. An example
is the MOSIX extension for Linux kernel.
My question and doubt is simple: is it possible to "merge" TDP and Adaptive Partitioning in order to extend "
transparently" the Adaptive Partiitioning load balancing to a set of distinct node?
TDP creates the infrastructure while Adaptive Partiitioning use it to optimize the processing across multiple node. All
the work can be done without a special framework or particular code like happens for other OSes.
What do you think about this?
Mario.
