Personal description:
I did manage to transform a bright theoretical idea to a final hightech scientific product – MCTDHBLaboratory: http://qdlab.org
MCTDHBLab is a free scientific crossplatform (Win/Mac/Linux) environment with a mouseclick interface designed to solve
TimeDependent Schrödinger Equation for bosons based on MultiConfigurational TimeDependent Hartree for Bosons method .
This is the result of effective intercommunications and interactions of many involved people, whom I have coherently driven towards the final result.

Packages created: MCTDHBLaboratory (2015), original MCTDHB package (2005present)
MCTDHBLaboratory is a scientific crossplatform (Win/Mac/Linux) environment with a mouseclick interface designed to solve TimeDependent Schrödinger Equation for bosons based on MultiConfigurational TimeDependent Hartree for Bosons method http://mctdhb.org. It solves coupled systems of nonlinear integrodifferential timedependent equations by utilizing different combinations of massive (MPI, OpenMP, CUDA) parallelization schemes. MCTDHBLab allows to analyze and visualize the solutions obtained. Two modifications of the MCTDHBLab are available: a serial version readytouse on standard desktops and a professional version designed for supercomputers – it supports all parallelization schemes and includes additional tools, e.g., sourcecodes for package development http://QDlab.org.
