Tensor contraction represents the most computer-intensive operation of many methods in quantum chemistry, condensed matter physics, nuclear physics, machine learning and quantum computing. We have identified an urgent need to create a standard for tensor libraries, similar to BLAS, which will pave the way for efficient tensor contraction on modern supercomputers. This was the focus of a three-day CECAM workshop, held at Le Village, Toulouse, May 22-24, 2024, and gathering major players from both developers, users and vendors.
The workshop was organized by two members of the LCPQ lab, Jan Brandejs and Trond Saue, in collaboration with André Severo Pereira Gomes (Lille), Lucas Visscher (Amsterdam) and Paolo Bientinesi (Umeä). Each day began with overview talks, bringing participants up to speed, followed by a panel discussion, setting the stage for breakout sessions in groups of 5-6 people. There was significant progress towards a unified low-level tensor contraction interface, and a working group was set up to continue this effort.
