Call For Papers: Seventh Annual Workshop on the LLVM Compiler Infrastructure in HPC


The Seventh Annual Workshop on the LLVM Compiler Infrastructure in HPC
Sunday, November 14, 2021 - St. Louis, Missouri, USA

Held in conjunction with SC21: The International Conference for High Performance Computing, Networking, Storage, and Analysis, and in cooperation with the IEEE Technical Consortium On High Performance Computing (TCHPC).


  • Paper submissions are due August 20, 2021 (AoE)
  • Notification of acceptance: September 14, 2021
  • Camera-ready papers due: Oct. 7th, 2021
  • Workshop: November 14, 2021

Please see the SC21 home page for registration deadlines and other information associated with the parent event.

Pending acceptance of the final workshop proceedings, the selected papers will be published by TCHPC.

Workshop Overview:

LLVM has become an integral part of the software-development ecosystem for optimizing compilers, dynamic-language execution engines, source-code analysis and transformation tools, debuggers and linkers, and a whole host of programming-language and toolchain-related components. Now heavily used in both academia and industry, where it allows for rapid development of production-quality tools, LLVM is increasingly used in work targeted at high-performance computing. Research in, and implementation of, program analysis, compilation, execution, and profiling has clearly benefited from the availability of a high-quality, freely-available infrastructure on which to build. This workshop will focus on recent developments, from both academia and industry, that build on LLVM to advance the state of the art in high-performance computing.

The workshop will feature contributed papers, selected lightning talks, and invited talks. We are seeking submissions for full papers and lightning talks.

General topics of interest include, but are not limited to:

  • Compiler design for highly-concurrent/parallel environments
  • Compilation techniques targeted at high-performance computing codes
  • Programming-language implementation techniques enabling high performance and high productivity
  • Embedding compilation and dynamic execution at scale
  • Tools for optimization, profiling, and feedback
  • Source code transformation and analysis
  • Gap analyses of open-source LLVM-based tools

Full Papers

Papers must be in IEEE conference format (templates are available: see workshop website for link). Papers should be no more than 12 pages (including references and figures) and must be at least eight pages long.

Lightning Talks

An abstract and one-page summary of proposed lightning talks are required for consideration. Deadlines and other dates match those for full paper submissions.

Please visit the workshop’s website at for updates and any additional details as the various deadlines approach.

Submissions for both Full Papers and Lightning Talks should be made through
