Description
pcard-67164
some benchmark models show worse performance on ips after turning on Auto-ecompute Flag. One of the reasons we've found is that SUM op which is recomputable actually will be changed into compute intensive REDUCE_SUM op and takes long time to run. Therefore we remove sum op from default recomputable ops.
