Building

GNAT Studio

To build in GNAT Studio, build or run the test_routers program.

Manually

To build manually, run

gprbuild [-jN] [-Xmode=debug|release]

Set N to the number of files you want to build in parallel.

The scenario variables are as follows

mode: Controls the level of optimisation and runtime checks built into the program
- debug (default): Build with minimal optimisation and stricter runtime checks, good for debugging and low compile time
- release: Build with high optimisation and looser runtime checks, good for testing performance of a correct program

For example, to compile a release build on 4 cores you can run:

gprbuild -j4 -Xmode=release

Running

Configuration

Available network topologies are denoted by name together with the parameters which are required for a given topology. For example, you can test your routers in a 4-d hypercube by:

./build/debug/test_routers -t Hypercube -d 4

Use the help flag to print the full configuration parameters

$ ./build/debug/test_routers -h
