YMsu3
This code simulates the pure gauge SU(3) theory with different boundary conditions (SF, open, twisted,…).
It can perform on-line measurements of gradient flow quantities with several fixed step-size or adaptive step-size integrators and for different flow definitions (See here and there for the details of the theoretical setup). It can also measure the Schrödinger Functional coupling.
The code is largely undocumented. What is interesting is that this code has been written completely in standard fortran 2008, using coarrays for parallel processing. The code shows very good strong scaling up to ~1024 cores in several practical simulations:
