mpi

This repo contains several mpi apps and algorithm based fault tolerant apps (mm, lu, kmeans).

• CRC32 is used to verify the integrity of communication data.
• Hamming code (SECDED) is used to correct one-bit errors and detect two-bit errors in data blocks.

MM

• Compile

make mm
make mm_abft
make mm_comp

• Run

mpirun -np <num_of_procs> bin/mm <matrix_a_filename> <matrix_b_filename>
mpirun -np <num_of_procs> bin/mm_abft <matrix_a_filename> <matrix_b_filename>
mpirun -np <num_of_procs> bin/mm_comp <matrix_a_filename> <matrix_b_filename> [CT]

• A small program gen_matrices.py helps to generate a matrix.
• Requirement
  • m_1->cols == m_2->rows
  • m_1->rows % num_worker == 0

LU

• Compile

make lu
make lu_abft
make lu_comp

• Run

mpirun -np <num_of_procs> bin/lu <matrix_size>
mpirun -np <num_of_procs> bin/lu_abft <matrix_size>
mpirun -np <num_of_procs> bin/lu_comp <matrix_size> [CT]

K-means

• Compile

make kmeans
make kmeans_abft
make kmeans_comp

• Run

mpirun -np <num_of_procs> bin/kmeans [clusters] [max_iterations] [datafile] # (default) 100 1000 ./data/obs_info.txt
mpirun -np <num_of_procs> bin/kmeans_abft [clusters] [max_iterations] [datafile] # (default) 100 1000 ./data/obs_info.txt
mpirun -np <num_of_procs> bin/kmeans_comp [CT] # CT, clusters, max_iterations, datafile are set in include/dataCompression.h

Himeno

• Parameter Setting

cd src/himeno
./paramset.sh M 1 1 2 # generate new param.h

• Compile

make himeno
make himeno_comp

• Run

mpirun -np <num_of_procs> bin/himeno

Graph500

• Compile

cd src/graph500/mpi/
make

• Run

cd src/graph500/mpi/
./graph500_mpi_simple <scale> [edge-factor-default-16]

PingPong

• Compile

make pingpong_float_comp
make pingpong_double_comp

• Run

mpirun -np 2 ./bin/pingpong_float_comp
mpirun -np 2 ./bin/pingpong_double_comp
