Evaluating the Impact of TLB Misses on Future HPC Systems

Abstract

TLB misses have been considered an important source of system overhead and one of the causes that limit scalability on large supercomputers. This assumption lead to HPC lightweight kernel designs that usually statically map page table entries to TLB entries and do not take TLB misses. While this approach worked for petascale clusters, programming and… (More)
