| integrator (const config &cfg) | |
| Pass on constructor. | |
| virtual void | integrate () |
| Interfaces function to integrate, for use by general user. More... | |
| virtual void | core_integrate () |
| To integrate without any bookkeeping. More... | |
| virtual void | set_log_manager (log::Pmanager &l) |
| Read the GPU log object from log manager and set it. | |
| void | set_log (gpulog::device_log *log) |

| void | download_ensemble () |
| Synchronize host ensemble with device ensemble. | |
| Public Member Functions inherited from swarm::integrator | |
| integrator (const config &cfg) | |
| Inetgrator class should be configurable. Derived instances should also have a constructor with similar signature and pass on the config parameter. | |
| virtual void | flush_log () |
| Flush the host log. | |
| virtual defaultEnsemble & | get_ensemble () |
| Access the ensemble subject to integration. | |
| virtual void | set_destination_time (const double &destination_time) |
| Set the time marker to end the integration. | |
