Subject: [Trilinos-Users] playing with overlaped map

Dear all,
I need to do something with overlapped map, which has no one-to-one correspondence between global index and the pair of a local index and a processor number.
Then, how do I do some operation without overlapping?

For example
RCP<MultiVector> mutivector = rcp(new MultiVector(map,2) )
numMyElement = vector.getMaxLocalIndex()
For (int i=0;i<numMyElement;i++){
           multivector.sumIntoLocalValue(i,0,&val);
}


If I print ‘multivector’, I can check the printed values are multiply added.

Is there good way to my case?

Sincerely
Sunghwan Choi
