CACHP @ PPoPP 2026

Workshop on Co-evolution of Algorithms, Compilers, and Hardware for Performance (CACHP)
Co-located with PPoPP 2026
31 January – 4 February 2026
Sydney, Australia

• Submission site: https://easychair.org/conferences/?conf=cachp26

Achieving performance requires advances in various aspects, including algorithms,  programming models, software construction, compilers, and hardware. Progress in each of these areas influences and reshapes the others. For example, a new code pattern may first appear as a hand-crafted optimization by an expert programmer, then evolve into a portable compiler transformation, and eventually inspire changes in hardware architecture or system design. Such cross-pollination drives innovation, yet opportunities for the communities to engage in joint discussion remain limited.

The workshop will be organized as a half-day event (approximately four hours). We are soliciting talk proposals to introduce recent advances as well as challenges that could shape the next generation of research. Importantly, the workshop emphasizes idea exchange rather than publication, so it does not require proceedings.

Paper Submission
All submissions must be made electronically through EasyChair (https://easychair.org/conferences/?conf=cachp26). A submission should include the abstract and a high-level description of the work covered by the proposed talk. Each talk is around 20 minutes. All submissions must include a title, an abstract, and a description of the talk, and should be no longer than one page. Authors can provide additional links to related publications. A talk can feature one or multiple publications (e.g., a series of related ones). We especially encourage work that covers novel designs of algorithms, compilers, or hardware inspired by one another. Submissions will be peer-reviewed, and accepted submissions will be invited to give talks at the workshop.

We do not have a strict format requirement since the workshop does not require proceedings. Using the ACM SIGPLAN template is recommended.
