lijie Abstract– Drone is a flying robot that can be remotely controlled or fly autonomously, which has been used in a wide range of areas. The quadcopters, that with four rotors are the most popular drones. Due to the propellers rotate at high speed and are normally exposed, they can cause serious injury if get caught … Read more
Abstract—Understanding the status of high-performance computing platforms and correlating applications to resource usage provide insight into the interactions among platform components. A lot of efforts have been devoted into developing monitoring solutions; however, a large-scale HPC system usually requires a combination of methods/tools to successfully monitor all metrics, which will lead to a huge effort … Read more
Abstract-Stencil computation is a classic computational kernel present in many high-performance scientific applications, like image processing and partial differential equation solvers (PDE). A stencil computation sweeps over a multi-dimensional grid and repeatedly updates values associated with points using the values from neighboring points. Stencil computations often employ large datasets that exceed cache capacity, leading to … Read more
Abstract—The modern microprocessor architecture mainly utilizes multi-level data caches as a primary optimization to reduce the memory access latency and power consumption as well as increase the perceived bandwidth from an application. This mechanism works well with significant memory reuse or linear memory access patterns. However, the irregular or nondeterministic pattern of memory access will … Read more
