## Detailed Description

Distributes shell pairs either statically or dynamically.

## Constructor & Destructor Documentation

sc::DistShellPair::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.

Both static (round-robin) and dynamic methods are supported.

## Member Function Documentation

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.
