The 2nd Workshop on Heterogeneous Memory Systems (HMEM 2021) will be 
held virtually on June 18, 9.00-13.00 EDT / 15.00-19.00 CEST.

Heterogeneous memory architectures have recently emerged and 
revolutionized the traditional memory hierarchy. Today’s architectures 
may comprise multiple memory nodes, organized in complex non-uniform 
access (NUMA) topologies, whose nodes include not just DRAM, but also 
die-stacked DRAM, high-bandwidth multi-channel RAM, or persistent memory.

By combining different memory technologies, heterogeneous memory 
architectures allow today’s systems to take advantage of the strengths 
of each technology — namely, in terms of latency, bandwidth, capacity, 
persistence or cost. As a result, applications may benefit from improved 
performance, energy-efficiency, and cost trade-offs.

Still, exploiting the full potential of heterogeneous memory 
architectures poses significant challenges. Since heterogeneous memory 
architectures introduce dramatic disruptions to the usual memory 
hierarchy assumptions that have guided decades of system and software 
design, we need to rethink the full system stack to embrace the new era 
of memory heterogeneity.

Following a successful inaugural edition at ICS 2020, the 2nd HMEM 
workshop will serve as a forum to present and discuss ongoing research 
around heterogeneous 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.

Topics of interest include, but are not limited to:

- Data allocation and placement in heterogeneous memories
- Caching for heterogeneous memories
- Software-defined far memories
- Disaggregated memory
- New memory consistency and persistency models
- Persistent data structures
- Abstractions and support for failure-atomicity in persistent memory
- Use cases and early experiences

Prospective authors must submit an extended abstract of up to 4 pages 
through EasyChair. Prospective speakers are also welcome to submit 
extended abstracts based on their recent publications.

This is a traditional-style workshop without formal papers or 
proceedings. The authors of accepted communications will be invited to 
(optionally) upload their extended abstract (PDF) for publication in the 
workshop website.

Submission deadline: May 29, 2021 (AOE)
Acceptance notification: June 4, 2021
