1. This slides presents title of the proposed project • State also the purpose and your name • Optionally thank your audience “Temperature-Aware Task Scheduling for Multicore Processors” Masters Thesis Proposal by MynameMyname

2. Temperature-Aware Task Scheduling This slides presents an outline of the presentation Presentation Overview Thesis Motivation Thesis Aim and Innovation Thesis Contributions and Objectives The Temperature-Aware Task Scheduling Unit Evaluation Methodology Work Planning

3. Motivation: The Temperature Wall Problem • Processor Performance • Measure of the execution time of application programs • Dominated by • Processor Architecture • Clock Frequency • Processor Power Consumption Depends on • Clock Frequency • Processor Voltage • Processor Activity • Type of instructions executed This slides presents your thesis motivation. Start with the problem and state why it is essential to address it

4. Motivation: The Temperature Wall Problem (Cont.) • The Temperature Wall Problem • Increase performance by increasing Clock Frequency • Increase in Clock Frequency increases Power Consumption • Power Consumption converted to Heat and Temperature Increase • Reduce Clock Frequency to Cool Processor, thus Reduce Performance This slides presents your thesis motivation. Start with the problem and state why it is essential to address it  Need another way to keep processor’s temperature low

5. Motivation: Task Scheduling on Multicore Processors • Multicore Processors • Achieve higher performance using • More than one simpler processors (Cores) • Operating in Parallel • Task Assignment to Cores affects • Hardware Complexity • Processor Performance • Existing Task Assignment Methodologies: • Round Robin • Cache Affinity This slides presents your thesis motivation. Start with the problem and state why it is essential to address it  Consider Core Temperature in deciding on Task Assignment

6. Thesis Aim • Design, Implement and Evaluate a Temperature-Aware Task Scheduling System for Multi-core Processors • Tasks assigned to the idle core with lowest temperature • Thus, avoid overheating the processor • ……….. • ………………. This slides presents your proposed solution to the problem. Justify also why

7. Thesis Innovation • The proposed task scheduling system is innovative, • Schedule task according to the temperature of each core, • Avoid reducing the clock frequency, • Thus avoid performance degrading. • ……. This slides presents your thesis innovation. Thesis innovation must be clearly stated. It affects the final assessment of your proposal

8. Thesis Contributions (a) Design the Temperature-Aware Task Scheduling Unit. (a1) Development of the Hardware modules needed to • record the temperature at the surface of each core of the processor chip • determine the lowest of the temperatures of the idle cores. (a2) Development of a compiler preprocessor that will annotate each thread with its computation and data access characteristics. (b) Evaluate the Temperature-Aware Task Scheduling Unit. (b1) …… (b2) ….. This slides presents your contributions. Your contributions must be clearly stated from the beginning.
