Hello Dave,
I am trying to use my Mpz type inside a collective finish.
I have added a MulReducer<T> struct in Reducible.x10
but my program is failing either silently or with "Place 0 exited
unexpectedly with signal: Segmentation fault"
Here is a summary of the code:
val finalSum = finish(myMulReducer()){
ateach (z in D_Base) {
//calculate myFact - partial factorial in this place
offer myFact; //******failing here
}
};
return finalSum;
//......
static struct myMulReducer implements Reducible[Mpz] {
public def zero() = Mpz(0);
public operator this(a:Mpz, b:Mpz) = (a * b);
}
Is the offer causing the problem? Also tried to write partial results in a
DistArray and used reduce function, in which case I get a Termination error
Regards,
Konstantina
