Overview and scope
====================

The 6th HMEM workshop serves as a forum to present and discuss ongoing 
research around heterogeneity and memory systems. The scope of the 
workshop encompasses all the layers of system and software stack, from 
computer architectures, operating system, middleware, programming 
models, runtime systems, tools, to applications.

Heterogeneity is ubiquitous, not only in terms of processing units but 
also memories and networks. As heterogeneity increases, memory 
subsystems play an even more important role to attain performance, from 
their technology to the system architecture to the software management 
and programming model. While CPU-only compute nodes are becoming rare 
instances, heterogeneous memory architectures have recently emerged and 
revolutionized the traditional memory hierarchy. Today’s and upcoming 
architectures may well comprise multiple memory technologies next to 
DRAM, accelerators with dedicated memories, or even specific expansion 
cards hosting memory alone, such as: 3D-stacked memory, high-bandwidth 
multi-channel RAM, unified/shared memory on accelerators, Compute 
Express Link (CXL)-based architectures, persistent memory, or MRDIMMs.

As in previous years, the Workshop on Heterogeneous Memory Systems, now 
rebranded as Heterogeneity and Memory Systems (HMEM), will bring 
together different research efforts and expertise to the end of 
integrating different approaches and democratizing the use of resource 
heterogeneity from a memory perspective, to benefit applications not 
only in terms of performance, but also energy efficiency and cost 
trade-offs. The main goal of the workshop is to push the research 
frontiers forward by exchanging knowledge and debating ideas through 
featured talks, technical paper presentations, and interactive 
discussions. Overall, topics of interest include, but are not limited to:

  * Resource heterogeneity (e.g., accelerators) and memory implications,
    including memory designs, data layouts, etc.
  * Data allocation and placement techniques in heterogeneous memory systems
  * Caching for heterogeneous memory systems
  * Programming models and tools for complex/heterogeneous memory
    hierarchies
  * Software-defined far memories
  * Disaggregated memory and in-memory computing
  * Data movement in heterogeneous memory systems
  * Memory consistency and persistency models
  * Data structures for heterogeneous memory infrastructures
  * Abstractions and support for failure-atomicity in persistent memory
  * Emerging memory architectures and system configurations
  * AI on heterogeneous memory systems and use of AI for heterogeneous
    memory systems
  * Use cases, early experiences and performance evaluations

Submissions
====================

This is a traditional-style workshop without formal proceedings. The 
authors of accepted submissions will give a talk at the workshop and 
participate in the closing discussion panel. Additionally, authors will 
be invited to (optionally) upload their submitted paper (PDF) to be 
shared on the workshop website. A paper accepted to the HMEM workshop 
does not preclude its future publication at a major conference.

Submissions must use the ACM proceedings template (for Latex users, 
version 1.90 (last update April 4, 2023) is the latest template, and 
please use the “sigconf” option).

We accept two types of submissions.

A first type of submission includes position papers as well as papers 
that describe completed or early-stage work. Such submissions are 
limited to 12 pages including references and figures.
Extra pages can be included in a clearly marked appendix (to be read at 
the discretion of the reviewers). Submitted papers must not include 
author names (double-blind review).

We also welcome 2-page abstracts that summarize recently 
accepted/published at top-tier conferences/journals. In this case, the 
author names and references to the published works should be included in 
the abstract.
