Description of problem: The cpu-partitioning profile is setting up CPUAffinity in the system, but not in the initrd image. This causes initrd to run without CPUAffinity, which in turn causes systemd initialization code to run on isolated CPUs during initrd time, creating timers that will keep ...

But, There is no LLC access rules between CPU and GPU, so if GPU and CPU processes run together at the same time, performance of both processes gets worse because of the contention on the LLC. This Paper gives evidence to prove the need of the Cache Partitioning and is mentioned about ...
Time partitioning distributes CPU time within a specified period into logical divisions termed as partitions, which are made up of more than one thread. Through dynamic partitioning, the operating system is able to vary the length of time each partition receives during a processing cycle. The QNX...
HISA extends the CPU-based trusted execution environment (TEE) to the heterogeneous FPGA components to enhance the security of the CPU-FPGA system. To securely offload the application to the FPGA part of HISA, we develop ApproVer to verify the security of the FPGA IP cores by applying an ...
The language simplifies the application development while generating code for multiple devices, such as CPU and GPU. The integration with RT allows for efficient multiple node hybrid execution. We also developed a novel cost-aware data partitioning (CADP) strategy that considers the workload ...
design space exp1oration for partitioning dataf1ow program on cpu gpu heterogeneous systemDataflow programming is a methodology that enables the development of high-level, parametric programs that are independ- ent of the underlying platform. This approach is particularly useful for heterogeneous ...
We also propose a performance model for each static partitioning strategy to perform the distribution of the work between the processors. We evaluate the performance of all three partitioning methods by considering the execution time and the load imbalance between the CPU and GPU as performance metr...
of tasks between CPU and GPU is determined according to problem scales; automatically adjusting the partitioning proportion of tasks in the whole executing processes of an application according to the actual measurement performance of CPU and GPU, thus realizing the load balance of task partitioning. ...
