Continual demand for memory bandwidth has made it worthwhile for memory vendors to reassess processing in memory (PIM), which enables higher bandwidth by placing compute units in/near-memory. As such, memory vendors have recently proposed commercially ...

Large Language Models increasingly rely on distributed techniques for their training and inference. These techniques require communication across devices which can reduce scaling efficiency as the number of devices increases. While some distributed ...

The pace of advancement of the top-end supercomputers historically followed an exponential curve similar to (and driven in part by) Moore's Law. Shortly after hitting the petaflop mark, the community started looking ahead to the next milestone: Exascale. ...

There have been numerous studies on heterogeneous memory systems comprised of faster DRAM (e.g., 3D stacked HBM or HMC) and slower non-volatile memories (e.g., PCM, STT-RAM). However, most of these studies focused on static policies for managing data ...

For efficient placement of data in flat-address heterogeneous memory systems consisting of fast (e.g., 3D-DRAM) and slow memories (e.g., NVM), we present a hardware-based page migration technique. Unlike epoch-based approaches that migrate heavily ...

With the emergence of 3D-DRAM, Processing-in-Memory has once more become of great interest to the research community and industry. Here we present our observations on a subset of the PIM design space. We show how the architectural choices for PIM core ...

The promise of 3D-stacked memory solving the memory wall has led to many emerging architectures that integrate 3D-stacked memory into processor memory in a variety of ways including systems that utilize different memory technologies, with different ...

The ultimate goal of this research is to incorporate facial animation based on image morphing in a very narrow bandwidth video transmission, especially in video conferencing, news telecast etc., where the background as well as the object in the image ...
