Benchmarks library

A static library libmpib.a implements point-to-point and collective benchmarks. Main library modules (the modules marked grey can be extended, providing the benchmarking of user-defined point-to-point and collective operations):

• Measurement: base data structures and functions (depends on the GNU Scientific Library)
• Operation-specific benchmarks (now includes only benchmark for bcast)
• Point-to-point benchmarks (seqential/parallel point-to-point benchmark)
• Collective benchmarks (collective benchmarks based on root, max and global timing methods)
• Containers for collective communication operations (data structures describing collective communications to be measured, which are used as an argument of collective benchmark functions)
• Definitions of MPI communication operations (definitions of MPI communication operations)

Tools

• P2P benchmark
• Collective benchmark
• Generator of multiplying factors for benchmarking scatterv/gatherv

Command-line arguments are described in Options for executables.

Tests

• sg-based-p2p
• Point-to-point communication by fragmenting in a hybrid MPI/OpenMP approach
• Eager protocol point-to-point benchmark
