[Paraview] Multi-core custom applications

[Burlen Loring]

for me every run is different, sometimes I want to use 2 cores others I 
want to use 16. my thinking is that we need a way to set the number of 
cores before the server starts up. It sounds like others are 
encountering situations where they need to tweak the startup parameters 
as well.  and why not just make use of the existing infrastructure for 
specifying those run parameters? The connect to mechanism isn't just for 
remote servers, also works fine for local ones, and it's easy to add 
dialog entries for parameters by pvsc. Perhaps the multicore just starts 
the connect to process at the pvsc dialog, based on a baked in multicore 
pvsc, which could potentially be configured during the build/install? 
Also internally, for example in the memory inspector, we currently need 
to handle the multicore server differently than any other server (it's 
actually currently broken for multicore because of this). even though 
it's really no different than any other server, at least judging from 
the command line displayed in the terminal.
