----------------------------------------
Summary: ALS-CG fails w/ codegen fuse-all heuristic optimizer
Key: SYSTEMML-1963
URL: https://issues.apache.org/jira/browse/SYSTEMML-1963
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
When using the heuristic fuse-all codegen optimizer, ALS-CG fails on compiling
the following operator:
{code}
public final class TMP24 extends SpoofRowwise {
public TMP24() {
super(RowType.FULL_AGG, -1, false, 3);
}
protected void genexec(double[] a, int ai, SideInput[] b, double[] scalars,
double[] c, int len, int rix) {
double[] TMP14 = LibSpoofPrimitives.vectNotequalWrite(a, 0, ai, len);
double[] TMP15 = LibSpoofPrimitives.vectMinusWrite(b[0].values(rix), a,
b[0].pos(rix), ai, b[0].clen);
double[] TMP16 = LibSpoofPrimitives.vectPowWrite(TMP15, 2, 0, TMP15.length);
double[] TMP17 = LibSpoofPrimitives.vectMultWrite(TMP14, TMP16, 0, 0,
TMP14.length);
double TMP18 = LibSpoofPrimitives.vectSum(TMP17, 0, TMP17.length);
c[0] += TMP18;
}
protected void genexec(double[] avals, int[] aix, int ai, SideInput[] b,
double[] scalars, double[] c, int alen, int len, int rix) {
double[] TMP19 = LibSpoofPrimitives.vectNotequalWrite(avals, 0, aix, ai,
alen, len);
double[] TMP20 = LibSpoofPrimitives.vectMinusWrite(b[0]vals, a, b[0]ix,
b[0].pos(rix), ai, alen, b[0].clen);
double[] TMP21 = LibSpoofPrimitives.vectPowWrite(TMP20, 2, 0, TMP20.length);
double[] TMP22 = LibSpoofPrimitives.vectMultWrite(TMP19, TMP21, 0, 0,
TMP19.length);
double TMP23 = LibSpoofPrimitives.vectSum(TMP22, 0, TMP22.length);
c[0] += TMP23;
}
}
{code}
