There are two ways to submit PPML jobs:

PPML CLI

Description

The PPML Command Line Interface is a unified tool to submit PPML spark jobs on a cluster.

Synopsis

Once a user application is bundled, it can be launched using the bigdl-ppml-submit.sh script. This script takes care of setting up SGX configuration and cluster & deploy mode, running PPML jobs in a secured environment:

./bigdl-ppml-submit.sh [options] <application-jar> [application-arguments]

Options

  • The following parameters enable Spark executor to run in SGX. Check the recommended configuration of SGX.

    --sgx-enabled true -> enable Spark executor running on SGX, false -> native on k8s without SGX. The default value is false. Once --sgx-enabled is set as true, you should also set other sgx-related options (--sgx-log-level, --sgx-driver-memory, --sgx-driver-jvm-memory, --sgx-executor-memory, --sgx-executor-jvm-memory) otherwise PPML CLI will throw an error.

    --sgx-driver-jvm-memory Set the SGX driver JVM memory. The recommended setting is less than half of driver SGX EPC memory, in the same format as JVM memory strings with a size unit suffix ("k", "m", "g" or "t") (e.g. 512m, 2g).

    --sgx-executor-jvm-memory Set the SGX executor JVM memory. The recommended setting is less than half of executor EPC memory, in the same format as JVM memory strings with a size unit suffix ("k", "m", "g" or "t") (e.g. 512m, 2g).

  • Except for the above SGX options, other options are exactly the same as Spark properties

    --master The master URL for the cluster (e.g. spark://23.195.26.187:7077)

    --deploy-mode Whether to deploy your driver on the worker nodes (cluster) or locally as an external client (client) (default: client)

    --driver-memory Amount of memory to use for the driver process, in the same format as JVM memory strings with a size unit suffix ("k", "m", "g" or "t") (e.g. 512m, 2g).

    --driver-cores Number of cores to use for the driver process, only in cluster mode.

    --executor-memory Amount of memory to use per executor process, in the same format as JVM memory strings with a size unit suffix ("k", "m", "g" or "t") (e.g. 512m, 2g).

    --executor-cores The number of cores to use on each executor.

    --num-executors The initial number of executors.

    --name The Spark application name is used by default to name the Kubernetes resources created like drivers and executors.

    --verbose Print out fine-grained debugging information

    --class The entry point for your application (e.g. org.apache.spark.examples.SparkPi)

    application-jar: Path to a bundled jar including your application and all dependencies.

    application-arguments: Arguments passed to the main method of your main class, if any.

Usage Examples

If you want to enable the Spark security configurations as in Spark security configurations, export secure_password before invoking PPML CLI to enable it.

export secure_password=`openssl rsautl -inkey /ppml/trusted-big-data-ml/work/password/key.txt -decrypt </ppml/trusted-big-data-ml/work/password/output.bin`

Submit Spark-Pi job (k8s cluster mode, SGX enabled)
