# Large input forces a Spark-resident output. The following unary operations
# are individually cheap but their input already has a Spark output, so the
# transitive exec-type decision should pull them into Spark.
X = rand(rows=10000, cols=200, seed=42);
sp1 = X + ceil(X);  # spark transformation -> spark output
sp2 = round(sp1);   # unary on spark input
sp3 = abs(sp2);     # unary on spark input
sp4 = sp3 * 2.0;    # binary matrix-scalar on spark input
R = sum(sp4);
write(R, $1, format="text");
