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.

Documentation

User's Manual PDF

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:
get mupi-current-arch.tar.Z [Linux\|Mac\|Cray\|BlueGene] tar -zxvf mupi-current-arch.tar.gz cd mupi/examples make mpiping -np 2 mpiping -nvp 4

Download

Please accept the terms and disclaimer before downloading and using the software.
Downloading implies acceptance.
Download the most recent version for your platform:
mupi-current-arch.tar.Z Intel Linux | Intel Mac OS X | Cray XT5 | BlueGene P
Follow the installation instructions in the user manual.

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.
