Josh,
I got it to compile.
My current version looks like this.
/**
* Method to multiply matrix A with vector v
*/
def ClassicMatrixMultiply() {
finish ateach (p in v2.dist() ) {
val j = (p.coords())(0);
val r = ( ([j..j] as Region(1))
* A.region.projection(1))
as Region(A.rank());
val d = A.dist().intersection(r);
val linev = (v as Array[double](d));
v2(p) = ((A|r)*linev).reduce(double.+,0);
}
finish v = (v2 as Array[double](v.dist()) );
}
But now it generates tons of exceptions when run on two processors. Do you see
anything wrong here ?
