Page-based virtual memory improves programmer productivity, security, and memory
utilization, but incurs performance overheads due to costly page table walks after TLB …

Effective huge page management in operating systems is necessary for mitigation of
address translation overheads. However, this continues to remain a difficult area in OS …

Multi-socket machines with 1-100 TBs of physical memory are becoming prevalent.
Applications running on such multi-socket machines suffer non-uniform bandwidth and …

Virtualization provides benefits for many workloads, but the overheads of virtualizing
memory are not universally low. The cost comes from managing two levels of address …

Performance isolation is an important goal in server-class environments. Partitioning the last-
level cache of a chip multiprocessor (CMP) across co-running applications has proven …

Address translation is fundamental to processor performance. Prior work focused on
reducing Translation Lookaside Buffer (TLB) misses to improve performance and energy …

Fork has long been the process creation system call for Unix. At its inception, fork was hailed
as an efficient system call due to its use of copy-on-write on memory shared between parent …

Computer systems designers are building cache hierarchies with higher capacity to capture
the ever-increasing working sets of modern workloads. Cache hierarchies with higher …

Nonvolatile memory (NVM) technologies have gained increasing attention thanks to their
density and durability benefits. However, leveraging NVM can cause a crash consistency …

Computers continue to diversify with respect to system designs, emerging memory
technologies, and application memory demands. Unfortunately, continually adapting the …
