Theory vs. Experiments

Submissions must indicate their category during the submission process:

• B. Experiments (main contributions are experimental)
• C. Theory and Experiments (main contributions are a mix of theory and experiments)

Review Process

Double-Blind Policy

SPAA 2025 employs a lightweight double-blind review process.

• Submissions must omit authors’ names, affiliations, and contact information.
• References to prior work by the authors should be made in the third person.
• Any supplemental materials must also be anonymized.
• Authors are free to disseminate their ideas or draft versions of the paper (e.g., via arXiv or talks).
• Reviewers are asked to refrain from actively looking for author identities.

Conflict of Interest Policy

Authors must register their conflicts with PC members at the submission site. Conflicts include:

• Academic advisor or advisee (no time limit)
• Postdoctoral mentor or mentee (no time limit)
• Collaborators within the past three years (joint research, development, paper, or 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
• Anyone whose relationship would prevent objectivity

Falsely declared conflicts risk rejection. Contact the program chair for clarification on any uncertainties.

Registration and Travel

• Hotel Booking: SPAA Hotel Booking (Cut-off date: July 7, 2025)
• Registration: SPAA registration
• VISA Support: Fill out the ACM form to request a VISA support letter.
• Student Travel Grants: Information available on the student travel grants page.

Awards

SPAA recognizes outstanding contributions through:

• SPAA Best Paper Award
• SPAA Test-of-Time Award
• SPAA Parallel Computing Award

Additional Information

• SPAA follows the ACM anti-harassment policy.
• Workshops and tutorials are also part of the conference program.
