aDSA is a Partition Communication Subsystem (PCS) for Ada’s Distributed Systems Annex (Annex E), replacing the discontinued PolyORB/GLADE runtime. alr build produces two ordinary tools:

• pcs_gnatdist – the gnatdist replacement: builds a distributed application from its .cfg, auto-assembling the GARLIC runtime (a --RTS overlay of the toolchain’s own runtime) on first use and re-assembling it when the toolchain changes;
• pcs_supervisor – launches and restarts a built deployment per its .manifest.

System prerequisites beyond the toolchain: libzmq >= 4.x and zlib (pacman -S zeromq, apt install libzmq3-dev, pkg install libzmq4; Windows setup is in the README’s Platforms section).
