[Paraview] reading input directly from memory?

[Anton Shterenlikht]

Is there a facility in paraview to read input
data directly from memory? I'm thinking of a situation
where some program is run on N cores. Before it exits,
while its data is still in memory, Paraview is started on
the same N cores and reads data created by the first program
from memory. Then the program exits.

I guess something like this can be written from
scratch, but I wonder if there is any existing
facility in paraview to facilitate this.

Thanks
