Silo is a new in-memory database that achieves excellent performance and scalability on
modern multicore machines. Silo was designed from the ground up to use system memory …

Fuzzing is a software testing technique that finds bugs by repeatedly injecting mutated
inputs to a target program. Known to be a highly practical approach, fuzzing is gaining more …

What opportunities for multicore scalability are latent in software interfaces, such as system
call APIs? Can scalability challenges and opportunities be identified even before any …

We analyze the manycore scalability of five widelydeployed file systems, namely, ext4, XFS,
btrfs, F2FS, and tmpfs, by using our open source benchmark suite, FXMARK. FXMARK …

This paper presents three building blocks for enabling the efficient and safe design of
persistent data stores for emerging non-volatile memory technologies. Taking the fullest …

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 …

The operating system is tasked with maintaining the coherency of per-core TLBs,
necessitating costly synchronization operations, notably to invalidate stale mappings. As …

This paper presents yet another concurrency control analysis platform, CCBench. CCBench
supports seven protocols (Silo, TicToc, MOCC, Cicada, SI, SI with latch-free SSN, 2PL) and …

Most database management systems cache pages from storage in a main memory buffer
pool. To do this, they either rely on a hash table that translates page identifiers into pointers …

Emerging persistent memory technologies, like PCM and 3D XPoint, offer numerous
advantages, such as higher density, larger capacity, and better energy efficiency, compared …
