Call for Papers

The 35th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA ’23) will run from June 17th to June 19th, 2023. Workshops and tutorials will be on June 16th. SPAA 2023 will be held as part of ACM FCRC in Orlando, Florida.

Submissions are sought in all areas of parallel and distributed computing, including algorithms, data structures, computational models, complexity theory, architectures, performance engineering, languages, runtime systems, compilers, programming systems, and networking systems. Papers that are purely theoretical, purely experimental, or contain both theory and experiments are welcome.  Topics of interest include, but are not limited to:

  • Parallel and Distributed Algorithms
  • Parallel, Concurrent, and Distributed Data Structures
  • Models for Parallel and Distributed Computing
  • Parallel and Distributed Architectures
  • Parallel Programming Languages
  • System Software for Parallel and Concurrent Programming (including but not limited to Runtime, Compilers, and Tools)
  • Parallel Programming Frameworks and Domain-Specific Languages
  • Management of Massive Data Sets
  • Transactional Memory Hardware and Software
  • Supercomputer Architecture and Computing
  • Routing and Information Dissemination
  • Peer-to-Peer Systems
  • Mobile, Ad-Hoc, and Sensor Networks
  • Synergy of Parallelism in Algorithms, Programming and Architecture
  • Memory or I/O-efficient algorithms
  • Parallel Complexity Theory
  • Green Computing & Power-Efficient Architectures
  • Instruction Level Parallelism and VLSI
  • Scheduling Algorithms for Parallel Machines

Submission Overview:

Please indicate in the title of your submission whether this is a regular paper or a brief announcement. All regular rejected papers automatically will be considered for brief announcements. Titles of regular papers which should not be considered for this option should mention “full paper only” after the title. To help find the appropriate reviewers for your submission, on the submission page please select the category that your submission falls under:

A. Theoretical (main contributions are theoretical)
B. Experimental (main contributions are experimental)
C. Mix of theory and experiments (main contributions are a mix of theory and experiments)

Please use your best judgement to select a single category, but if you really cannot decide on a single category, you may select more than one. This information will be used to help assign reviewers to papers based on their expertise.

Submissions must use the final ACM “sigconf” format from More details are at

Regular Papers:

A regular paper submission must report on original research that has not been previously or concurrently published.  Submitted manuscripts may not exceed ten (10) single-spaced double-column pages excluding bibliography. All necessary details to substantiate the claims of the paper should be included in a clearly marked appendix.  However, the reviewers are not obligated to read the appendix.  

Brief Announcements:

Examples of good brief announcements include: work in progress, announcement of tools/libraries, challenge problems posted to the community, and corrections to earlier results. Brief announcements may also include smaller results of interest. Submitted manuscripts may not exceed three (3) single-spaced double-column pages for brief announcements including bibliography.

Double-Blind Policy:

SPAA 2023 will employ a lightweight double-blind review process. That means, the submission should omit authors’ names, affiliations, and contact information. In addition, if the submission refers to prior work done by the authors, the reference should be made in third person. Any supplemental materials, if applicable, should also be anonymized. However, authors are free to disseminate their ideas or draft versions of the paper as they normally would, such as submitting them to arXiv or giving talks on their research ideas. The reviewers will be asked to refrain from actively looking for the identity of the authors via web search.

Conflict of Interest Policy:

To ensure a fair and high-quality reviewing process we ask ALL authors of a submitted paper to register their conflicts with the PC members at the submission site.  The following categories are considered as a conflict of interest:

  • Academic advisor or advisee (with no time limit)
  • Postdoctoral mentor or mentee (with no time limit) 
  • Collaborators within the past three years, including a joint research or development project, a joint paper, or a funding relationship
  • Members of the same institution within the past 3 years
  • Family members or close friends
  • Someone involved in an alleged incident of harassment (not required that the incident be reported)
  • Anyone whose relationship with an author would prevent the reviewer from being objective in his/her assessment

Note that if the program chair has reason to doubt the validity of the claim of conflict of interest, then they may request that a ToC advocate confidentially verify the reason for the conflict.  Falsely declared conflicts (i.e., do not satisfy one of the listed reasons) risk rejection without consideration of merit.  If an author believes that he or she has a valid reason for a conflict of interest not listed above or if he or she is uncertain, the author is encouraged to contact the program chair.

Additional Notes:

If an author has any further questions regarding the policies listed above, please contact the PC chair Julian Shun by email (jshun AT mit DOT edu) and prefix the subject title with “[SPAA 23]”.
