About

μπ is a simulator of parallel programs, especially focusing on very large-scale MPI programs (104-105 MPI ranks).

μπ is built as an application of the μsik PDES engine, portable to several platforms, including Windows, Mac and Unix/Linux, clusters machines, as well as on supercomputers such as Cray XT5 and Blue Gene P.

Current Capabilities (partial list)

  • Parallel discrete event simulation of MPI programs
  • Easy to retarget MPI applications to compile and link to simulator
  • Promise of scalability to many thousands of virtual MPI ranks
  • Full stack-based context, and actual code execution

What's New

  • Preliminary FORTRAN support
  • Application arguments (C/C++ only)
  • Actual data transfer across virtual MPI tasks
  • Expanded set of MPI routines (added: MPI_Isend/Irecv/Waitall)
  • See Release Notes for additional information.

 

Quick Start

For those impatient, like me:
  1. get mupi-current-arch.tar.Z [Linux|Mac|Cray|BlueGene]
  2. tar -zxvf mupi-current-arch.tar.gz
  3. cd mupi/examples
  4. make
  5. mpiping -np 2 mpiping -nvp 4

Download

Install and Run

  • tar -zxvf mupi-current-arch.tar.gz
Unwrap the package, say, in your home directory.
  • cd mupi/examples
 Go to the examples directory.
  • Edit Makfile
 Customize your MPI, C/C++ and FORTRAN compiler settings.
  • make
 This builds the default set of examples.
  • mpirun -np 2 mpiping -nvp 4
 Run the example: simulate 4 virtual MPI ranks, utilizing 2 real ranks for the simulation.
