Following a decade of radical advances in the areas of integrated photonics and computing
architectures, we discuss the use of optics in the current computing landscape attempting to …

Technologies like RDMA and Gen-Z, which give access to memory outside the box, are
gaining in popularity. These technologies provide the abstraction of far memory, where …

Recent heterogeneous architectures have trended toward tighter integration and shared
memory largely due to the efficient communication and programmability enabled by this …

We present Coup, a technique to lower the cost of updates to shared data in cache-coherent
systems. Coup exploits the insight that many update operations, such as additions and …

Cache coherence is an integral part of shared-memory systems but is also widely
considered to be one of the most complex parts of such systems. Much prior work has …

Cache coherence overhead in manycore systems is becoming prominent with the increase
of system scale. However, traditional electrical networks restrict the efficiency of cache …

Classification of data into private and shared has proven to be a catalyst for techniques to
reduce coherence cost, since private data can be taken out of coherence and resources can …

Performance bugs due to false sharing do not man-ifest as observable correctness errors,
and hence are challenging to detect and repair. Prior approaches aim to both detect and …

Modern processors employ multiple levels of caching to address bandwidth, latency and
performance requirements. The behavior of these hierarchies is determined by their …

Multicore processors are becoming dominant in todays computing environment. All
multicore processors are with cache coherent memory model. Users can have multiple …
