The growing disparity between CPU speed and memory speed, known as the
memory wall problem, has been one of the most critical and long-standing
challenges in the computing industry. To address the memory wall problem,
memory systems have been becoming increasingly complex in recent years. New
memory technologies and architectures are introduced into conventional
memory hierarchies. This newly added memory complexity plus the existing
programming complexity and architecture heterogeneity make utilizing
high-performance computer systems extremely challenging. Performance
optimization has shifted from computing to data access, especially for
data-intensive applications. Significant amount of efforts of a user is
often spent on optimizing local and shared data access regarding the memory
hierarchy rather than for decomposing and mapping task parallelism onto
hardware. This increase of memory optimization complexity also demands
significant system support, from tools to compiler technologies, and from
modeling to new programming paradigms. Explicitly or implicitly, to address
the memory wall performance bottleneck, the development of programming
interfaces, compiler tool chains, and applications are becoming memory
oriented or memory centric.

The organization of this workshop believe it is important to elevate the
notion of memory-centric programming to utilize the unprecedented and
ever-evaluating modern memory systems. Memory-centric programming refers to
the notion and techniques of exposing the hardware memory system and its
hierarchy, which include NUMA regions, shared and private caches, scratch
pad, 3-D stack memory, and non-volatile memory, to the programmer for
extreme performance programming via portable abstraction and APIs for
explicit memory allocation, data movement and consistency enforcement
between memories. The concept has been gradually adopted in main stream
programming interfaces, for example and to name a few, the use of place in
OpenMP and X10 and locale in Chapel to represent memory regions in a
system, the use of shared modifier in CUDA or cache modifier in OpenACC for
representing scratch-pad SRAM for GPUs, the memkind library and the recent
effort for OpenMP memory management for supporting 3-D stack memory (HBM or
HMC), and PMEM library for persistent memory programming. The MCHPC
workshop aims to bring together computer and computational science
researchers, from industry and academia, concerned with the programmability
and performance of the existing and emerging memory systems. The term
performance for memory system is general, which include latency, bandwidth,
power consumption and reliability from the aspect of hardware memory
technologies to what it is manifested in the application performance.

The topics of interest for the workshop include, but are not limited to:
  -- The challenges and existing solutions of programming 3-D stack memory,
NVDIMM, memristor and other processor/compute-in-memory technologies.
  -- Compiler and runtime techniques for optimizing data layout, movement
and consistency enforcement for latency hiding and for improving bandwidth
utilization and energy consumption of memory system that has different
memory technologies.
  -- Memory-centric programing interfaces or language extensions that
improve the programmability of using emerging memory technologies and
systems.
  -- Modeling, evaluation, and case study of memory system behavior that
reveals the limitation and characteristics of existing memory systems and
programming tool chains.
  -- New programming interfaces and implementation for providing shared
address space or distributed shared memory
  -- Programming interface, library and tools for memory allocation, data
movement and consistency control between memory of heterogeneous devices
such as CPU, GPU and FPGA.
  -- New abstract machine model for diverse memory system, new memory
performance and consistency model

All manuscripts will be reviewed and judged on correctness, originality,
technical strength, and significance, quality of presentation, and interest
and relevance to the workshop attendees. Submitted papers must represent
original unpublished research that is not currently under review for any
other conference or journal. Papers not following these guidelines will be
rejected without review and further action may be taken, including (but not
limited to) notifications sent to the heads of the institutions of the
authors and sponsors of the conference. Submissions received after the due
date, exceeding length limit, or not appropriately structured may also not
be considered. At least one author of an accepted paper must register for
and attend the workshop. Authors may contact the workshop organizers for
more information.
