Download QMCPACK v3.12.0
Notes
This release incorporates several hundred changes to QMCPACK and the supporting ecosystem. It is a recommended release for all users. Note that compilers supporting C++17 and CMake version 3.15 or newer are now required. Changes include newly added support for the DIRAC quantum chemistry code, the RMG-DFT code, and updates for the latest version of Quantum ESPRESSO. Through DIRAC it is now possible to perform highly accurate molecular calculations incorporating spin-orbit with multideterminant trial wavefunctions. Behind the scenes updates include increased checking of inputs, fixes to many edge case bugs, and removal of memory leaks in both QMCPACK and the various converters. In readiness for transition to the new batched drivers that support both CPU and GPU execution, more features are supported and performance improved. Test coverage and robustness is improved in all areas. For developers, tests, sanitizers, and code coverage are now run on Pull Requests using GitHub Actions.
