DistShellPair (const Ref< MessageGrp > &, int nthread, int mythread, const Ref< ThreadLock > &lock, const Ref< GaussianBasisSet > &bs1, const Ref< GaussianBasisSet > &bs2, bool dynamic, SharedData *shared=0) | |
The DistShellPair class is used to distribute shell pair indices among tasks. | |
void | init () |
Resets to the first shell pair. | |
void | set_debug (int d) |
How much stuff to print out. | |
void | set_print_percent (double p) |
How often to print status from node 0. | |
int | get_task (int &P, int &Q) |
Puts the current PQ shell pair into P and Q and returns 1. | |

This is used to store data that must be shared between all cooperating shell pairs. More... |

The DistShellPair class is used to distribute shell pair indices among tasks.
Both static (round-robin) and dynamic methods are supported.
int sc::DistShellPair::get_task | ( | int & | P, | |
int & | Q | |||
) |
Puts the current PQ shell pair into P and Q and returns 1.
When there are no more shell pairs to be processed by this processor, 0 is returned. Once we start doing get_tasks, we have to go to the end if dynamic load balancing is used.
P belongs to bs1, and Q belongs to bs2. If (bs1 == bs2) then P is greater or equal to Q.
