Purpose of matmul-sgx

This is a joint project between UniNE and BSC on the integration of OmpSs and Intel SGX. It consists of a parallel and secure version of the matrix multiplication problem. It performs the multiplication of two matrices (A and B) into a third one (C). Parallelization is achieved using OmpSs Programming Model and security is assured by means of Intel SGX.

How to Build/Execute

1. Install OmpSs
2. Install Intel(R) SGX SDK for Linux* OS
3. Make sure your environment is set:

   $ export TARGET=$HOME/ompss
   $ source ${sgx-sdk-install-path}/environment
   

4. Build the project with the prepared Makefile:
   1. Hardware Mode, Debug build:

      $ make
      

   2. Hardware Mode, Pre-release build:

      $ make SGX_PRERELEASE=1 SGX_DEBUG=0
      

   3. Hardware Mode, Release build:

      $ make SGX_DEBUG=0
      

   4. Simulation Mode, Debug build:

      $ make SGX_MODE=SIM
      

   5. Simulation Mode, Pre-release build:

      $ make SGX_MODE=SIM SGX_PRERELEASE=1 SGX_DEBUG=0
      

   6. Simulation Mode, Release build:

      $ make SGX_MODE=SIM SGX_DEBUG=0
      

5. Execute the binary directly:
   1. Sequential execution:

      $ OMP_NUM_THREADS=1 ./app
      

   2. Parallel execution:

      $ export n=number_of_threads
      $ OMP_NUM_THREADS=$n ./app
      

6. Remember to "make clean" before switching build mode
