Computers with hardware accelerators, also referred to as hybrid-core systems, speedup applications by offloading certain compute operations that can run faster on accelerators. Thus, it is not surprising that many of top500 supercomputers use accele

On the User–Scheduler Dialogue: Studies of User-Provided Runtime Estimates and Utility Functions

Autor: Cynthia Lee, Allan Snavely

Publikováno v: The International Journal of High Performance Computing Applications. 20:495-506

Effective communication between user and scheduler is an important prerequisite to achieving a successful scheuling outcome from both parties' perspectives. In a grid or stand-alone high-performance computing (HPC) enviroment, this communication typi

Publikováno v: ACM SIGARCH Computer Architecture News. 33:81-86

Trace-driven memory simulation tools such as MetaSim Tracer [1] capture the address stream of an application during an instrumented program run. Various statistics can be measured using the in-flight address stream including anticipated cache hit rat
