💖 ORTE_SSTORE(7) 💖

okay so bestie, welcome to the Open RTE MCA File Management (SStore) Framework — literally the scouting report for Open RTE's SStore framework plus a lil tour of some selected modules. and yes, this is the Open MPI 4.1.6 era manual page, so keep that in your notes 📝✨

🌸 DESCRIPTION 🌸

So SStore is this utility framework that OpenRTE uses for a bunch of stuff, and by "a bunch of stuff" I mean things like: moving checkpoint files around (transport, iconic), preloading user binaries, and preloading user files. it's giving backstage crew energy — you don't see it, but the whole show does not happen without it 💅

🎀 AVAILABLE COMPONENTS 🎀

These MCA parameters apply to all the components, no cap:

  • sstore_base_verbose — sets the verbosity level for literally every component. default is 0, which means silent except when there's an error (so it only speaks up when something's wrong, relatable 🙈).

🦋 central SStore Component 🦋

The central component implements a fully centralized stable storage mechanism — and heads up, it requires a shared storage medium (like, for example, NFS). that's a real requirement, not a suggestion, so plan accordingly 🫶

The central component has these MCA parameters:

  • sstore_central_priority — the component's priority, used when picking the most appropriate component for a run. think of it as its spot in the lineup 👑
  • sstore_central_verbose — sets the verbosity level for this component specifically. default is 0, aka silent except on error, same deal as above 💜
