This directory contains an example for running R in Graphene, including the Makefile and a template for generating the manifest. The application was tested on Ubuntu 16.04, with both normal Linux and SGX platforms.

Generating the manifest

Building for Linux

Run make (non-debug) or make DEBUG=1 (debug) in the directory.

Building for SGX

Run make SGX=1 (non-debug) or make SGX=1 DEBUG=1 (debug) in the directory.

Building with a local R installation

By default, the make command creates the manifest for the system R binary (/usr/lib/R/bin/exec/R). If you have a local R installation, you may create the manifest with the R_HOME variable set accordingly. For example:

make R_HOME=<install path>/lib/R SGX=1

Run R with Graphene

When running R with Graphene, please use the --vanilla or --no-save option.

Here's an example of running an R script under Graphene:

Without SGX:

./pal_loader R.manifest --slave --vanilla -f scripts/sample.r
./pal_loader R.manifest --slave --vanilla -f scripts/R-benchmark-25.R

With SGX:

SGX=1 ./pal_loader R.manifest --slave --vanilla -f scripts/sample.r
SGX=1 ./pal_loader R.manifest --slave --vanilla -f scripts/R-benchmark-25.R
