Causally Consistent Reversible Debugger for MPI

Running on linux

currently only x86 architecture is supported

build

make

compile target for debugger

There is a compiler included that wraps the mpi library calls, in order to enable the debugger to intercept and record them. Programs must be compiled with the included compiler script:

bin/compiler <path-to-target-MPI-program>

The compiled binary will be written to ./bin/targets/<source-file-name>. This path should be given to the debugger as input.

run

bin/orchestror <num_processes> <path-to-target-mpi-application-binary>

ℹ️ There's a couple of example programs included in the examples directory to test with. Compile them first (bin/compiler examples/<example-application-file>)



Other platforms (use Docker)

build

# in the project root directory
make dockerimage

Compiling MPI programs is not supported when running with docker. Use the included examples in bin/targets folder.

run

# use the included compiled examples
./runInDocker.sh <num_processes> bin/examples/<example-application-binary
