Call For Papers

The 31st IEEE International Symposium on High-Performance Computer Architecture (HPCA) will be held in Las Vegas, NV in 2025. HPCA is a high-impact premier venue for presenting research results on a wide range of computer architecture topics. Some topics of interest are listed below, but we encourage authors to contact the PC chair if they have a question regarding the topic fit:

  • Processor, memory, and storage systems architecture
  • Instruction-, thread-, and data-level parallelism
  • Interconnection networks and network interface architecture
  • Domain-specific architectures and Accelerators
  • FPGA, CGRA, and Reconfigurable systems
  • Near/In-Memory computing
  • Cloud, Datacenters, cluster/distributed systems
  • Approximate computing
  • Compilers/Languages/Runtimes for novel architectures
  • IoT, Mobile, Edge, and Embedded architectures
  • Effects of circuits or technology on architecture (3D/chiplets/interposer/wafer-scale)
  • Architecture modeling and simulation methodologies
  • Neuromorphic computing
  • Quantum, Superconducting and Emerging technologies impacting computer architectures
  • Reliability/Fault Tolerance, Energy Efficiency and Sustainability of Computer Systems
  • Security/Privacy
  • Evaluation and measurement of real computing systems


HPCA 2025 features a separate Industry Track with a separate call for papers. The goal of the HPCA Industry Track is to publish papers that are written by industry authors and their content relates to industrial products/processes.

Guidelines for Submissions

The purpose of having a paper registration deadline a week ahead of the actual paper submission is to overlap review assignments (which can take a long time) with giving you extra time to improve the quality of your submission. While we could have opted to freeze the title, authors and abstract fields by the paper registration deadline, we have decided against this, in order to provide you some flexibility in making modifications until the actual submission deadline. However, we do not want authors to misuse this flexibility. To adhere to the spirit of this intention, we need you to:

  • Please make the paper title as close to the final version as possible.
  • The author list should not change (order of authors can) after registration. If there is a change, you should send an email indicating the change at least 48 hours before the paper submission deadline to the PC chair.
  • Consequently the Conflict List should also be finalized by the abstract registration. ┬áPlease ensure it is accurate at the time of registration.
  • Please make the abstract as close to the final version as possible.

Flagrant violation of the above could result in an outright rejection of the submission
