Techniques for scheduling an application program running on a multiprocessor computer system are disclosed. Example methods include but are not limited to analyzing first, second, third, and fourth core components for any within-die process variation, determining an operating state of the first, second, third and fourth core components, selecting optimum core components for each component type with the aid of bloom filters, statically determining which core component types are used by the application program, and scheduling the application program to run on a core having an optimum core component for a core component type used by the application program.

Core selection for applications running on multiprocessor systems based on core and application characteristics

In accordance with the disclosed subject matter there is provided a method for segregating threads running in a computer system, and executing the threads according to this categorization.

Scheduling of threads by batch scheduling

Techniques for scheduling a thread running in a computer system are disclosed. Example computer systems may include but are not limited to a multiprocessor having first and second cores, an operating system, and a memory bank for storing data. The example methods may include but are not limited to measuring a temperature of the memory bank and determining whether the thread includes a request for data stored in the memory bank, if the temperature of the memory bank exceeds a predetermined temperature. The methods may further include but are not limited to slowing down the execution of the thread upon determining if the thread includes a request for data.

Scheduling threads on different processor cores based on memory temperature

The present disclosure generally describes systems, methods and devices for operating a computer system with memory based scheduling. The computer system may include one or more of an application program and a memory controller in communication with memory banks. The memory controller may include a scheduler for scheduling requests. The application program may select a scheduling algorithm for scheduling requests from a plurality of scheduling algorithms. The application program may instruct the scheduler to schedule requests using the selected scheduling algorithm.

Application selection of memory request scheduling

In accordance with the disclosed subject matter there are described techniques for segregating requests issued by threads running in a computer system.

Batch scheduling with thread segregation and per thread type marking caps

An integrated circuit chip is defined by a stack of several interconnected layers. The integrated circuit chip includes at least two layers of dissimilar metal patterned to define an array of integrated bimetallic thermocouples.

Bimetallic integrated on-chip thermocouple array

The present disclosure generally describes methods and systems for spectrum sensing within a cognitive radio. Example methods may include but are not limited to scanning radio frequencies within an initial portion of the radio frequency spectrum and analyzing the frequencies scanned within the initial portion. Example methods may also include but are not limited to dividing the initial portion into first and second portions, and selecting one of the first and second portions for further analysis.

Hierarchical spectrum sensing for cognitive radios

In accordance with various embodiments methods, systems and devices are described for transmitting a communication. The described methods include, but are not limited to, detecting spectrum holes and dividing the communication into first and second portions. The methods may also include transmitting the first portion at a first frequency and the second portion at a second frequency. The first and second frequencies may be different from each other, and the first and second frequencies may be within the spectrum holes.
