Existing serverless computing platforms are built upon homogeneous computers, limiting the
function density and restricting serverless computing to limited scenarios. We introduce …

Commodity computer systems contain more and more processor cores and exhibit
increasingly diverse architectural tradeoffs, including memory hierarchies, interconnects …

NUMA systems are characterized by Non-Uniform Memory Access times, where accessing
data in a remote node takes longer than a local access. NUMA hardware has been built …

Rapid growth of the demand for computational power has led to the creation of large-scale
data centers. They consume enormous amounts of electrical power resulting in high …

This paper presents the most exhaustive study of synchronization to date. We span multiple
layers, from hardware cache-coherence protocols up to high-level concurrent software. We …

On multicore systems contention for shared resources occurs when memory-intensive
threads are co-scheduled on cores that share parts of the memory hierarchy, such as last …

Multiprocessor application performance can be limited by the operating system when the
application uses the operating system frequently and the operating system services use data …

The next decade will afford us computer chips with 100's to 1,000's of cores on a single
piece of silicon. Contemporary operating systems have been designed to operate on a …

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 …

Machine Learning models are often composed of pipelines of transformations. While this
design allows to efficiently execute single model components at training time, prediction …
