> Key: SYSTEMML-1566
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1566

> Issue Type: Bug
> Reporter: Mike Dusenberry

> Fix For: SystemML 0.15
>
> Attachments: explain.txt, stats.txt

>
> For the 0.14 release testing, I tried out the [MNIST LeNet example |
> https://github.com/apache/incubator-systemml/blob/master/scripts/nn/examples/mnist_lenet-train.dml]
> on both 0.13 and 0.14 and noticed a possible regression. Basically, on 0.14
> the script took longer to run and had 2513 Spark instructions executed, while
> on 0.13 only 864 Spark instructions were executed. This was run locally on a
> laptop using the 2 instructions at the top of the script (and copied below).
> I've also attached the stats and runtime explain logs.
> 1. Download data
> {code}
> nn/examples/get_mnist_data.sh
> {code}
> 2. Execute from the {{scripts}} directory.
> {code}
> spark-submit --master local[*] --driver-memory 10G --conf
> spark.driver.maxResultSize=0 --conf spark.rpc.message.maxSize=128
> SystemML.jar -f nn/examples/mnist_lenet-train.dml -stats -explain -nvargs
