GPU Gross-Pitaevskii Equation numerical solver for rapidly rotating Bose-Einstein condensates. Further development and maintenance from https://github.com/GPUE-group/GPUE
Following the move to std::vector the tracking seems perfectly sane, but tends to locate hundreds of vortices at unexpected times during the evolution. This may likely be a sizing issue...
The issue shows up with the move to std::vector for the vortex tracking routines. Any more than a single vortex causes the system to fail. @ # #
The graph generation routine does not maintain the same UID order between simulations. Not a problem for initial selections and trajectories using python, but will be a problem if performing...
Add a flag that can be used to set a dissipative term for the GPE.
This will remove unnecessary on-device memory transfers and host-kernel calls. Not sure of the expected performance increase, but it should be beneficial.
Lots of old and unnecessary source files, functions and variables exist across the code. These should be removed for cleanliness.
Input of necessary parameters from an XML file would allow the generation of arbitrary potentials, wavefunctions, etc, and allow a more robust and easier to use code-base.
Use the symmetry of the split-operator method to remove unnecessary transforms between evolution steps. Will require a re-working of the angular momentum section. Perform half step into the algorithm, then...
The transfers should be faster for the printout, and when replacing the evolution operators. Use of pinned memory should help with this.
