mpi-abft-apps

This repo contains several algorithm based fault tolerant apps. Each app contains an original version and a modified abft version (_abft).

• 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

• 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>

• 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

• Run

$ mpirun -np <num_of_procs> bin/lu <matrix_size>
$ mpirun -np <num_of_procs> bin/lu_abft <matrix_size>

K-means

• Compile

$ make kmeans
$ make kmeans_abft

• 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
