But their (MPI) API is still standard conforming. The way they
integrated it (in the OS) is a bit different. IIUC they have their own
queue-ing system on top (or integrated). But OTOH neither SGE or PBS or
whatever is standard.
So from a programmer's POV, they conform to the MPI standard. From the
user's POV (how to launch a job or how to submit a job to a queue) there
was never any standard.
