This is the README for LULESH 2.0, MPI Sessions Proposal port.
If you have any questions please contact:
Dai Yang d.yang@tum.de or Amir Raoofy amir.raoofy@tum.de
- MPI Sessions Prototype, obtainable from https://github.com/caps-tum/MPI-Sessions-Sets
- An MPI distribution, e.g. OpenMPI
- C++ compiler and MPIC++ compiler
- Edit Makefile, edit CXXFLAGS and LDFLAGS according to the location of MPI sessions / MPI process sets
- Execute
make -j
- Due to the current limitation of our sessions prototype, test can be only conducted on a single node (shared memory machine)
- To test, you need to create a description file for the procoess set used for LULESH
echo lulesh 0-8 > lulesh8
- Experiments can be started with
mpirun -np 8 ./lulesh2.0 -s 40 -i 10 -p -ps ./lulesh 8 -repart 1
- Command Line parameters:
- -repart n sets whether dynamic repartitioing needs to be enabled, and which destination size is desired
- -repart_cycle sets at what cycle the repartitioning is initiated
- -ps specifies the process set specification file
- Currently only for Shared Memory system
- OpenMP is disabled
The original LULESH 2.0 is developed by Lawrence Livermore National Laboratory. Original code can be found at: https://github.com/LLNL/LULESH
