◆ LoadBalance() [1/7]

int LoadBalance ( Vector< Vector< int > > &  a_procAssignments,
Real a_effRatio,
const Vector< Vector< Box > > &  a_Grids,
const Vector< Vector< long > > &  a_ComputeLoads,
const Vector< int > &  a_RefRatios,
int  a_nProc = numProc() 
)

procAssignments output: processor number for each box effRatio output: ratio of min load to max load Grids input: meshes to balance ComputeLoads input: computational cost of each box RefRatios input: refinement ratio for each level

Referenced by blockReadLevel(), and readLevel().

◆ LoadBalance() [2/7]

int LoadBalance ( Vector< BoxLayout > &  Grids,
Real effRatio,
const Vector< Vector< long > > &  ComputeLoads,
const Vector< int > &  RefRatios,
int  nProc = numProc() 
)

Grids in-out: input grids to balance and output proc. numbers effRatio output: ratio of min load to max load ComputeLoads input: computational cost of each box RefRatios input: refinement ratio for each level

◆ LoadBalance() [3/7]

int LoadBalance ( Vector< int > &  a_procAssignments,
const Vector< Box > &  a_boxes,
const int  a_LBnumProc = numProc() 
)

convenience function to load balance a Vector of Boxes based on load=box.numPts()

◆ LoadBalance() [4/7]

int LoadBalance ( Vector< int > &  a_procAssignments,
const Vector< long long > &  a_computeLoads,
const Vector< Box > &  a_boxes,
const int  a_LBnumProc = numProc() 
)

convenience function to load balance a Vector of Loads based on load. boxes also passed in for possible use with box-swapping code

◆ LoadBalance() [5/7]

int LoadBalance ( Vector< int > &  a_procAssignments,
const Vector< long int > &  a_computeLoads,
const Vector< Box > &  a_boxes,
const int  a_LBnumProc = numProc() 
)

Accepts "long int" computeLoads and then just calls the "long long" version.

◆ UnLongLongLoadBalance()

int UnLongLongLoadBalance ( Vector< int > &  a_procAssignments,
const Vector< unsigned long long > &  a_computeLoads,
const Vector< Box > &  a_boxes,
const int  a_numProc = numProc() 
)

◆ basicLoadBalance()

int basicLoadBalance ( Vector< int > &  a_procAssignments,
int  numBoxes,
int  a_numProc = numProc() 
)

◆ LoadBalance() [6/7]

int LoadBalance ( Vector< int > &  procAssignments,
Real effRatio,
const Vector< Box > &  Grids,
const Vector< long > &  ComputeLoads 
)

◆ LoadBalance() [7/7]

int LoadBalance ( Vector< int > &  a_procAssignments,
Vector< Box > &  a_boxes,
const Box a_localGridBox,
const int  a_numProc = numProc() 
)

convenience function to gather a distributed set of Boxes with their corresponding processor assignment

Assumption is that each processor has at most one valid box. This is useful when interacting with other distributed codes which might not have the entire set of distributed boxes on all processors.
