Multicore option

[paorozo]

We need to include the option to change the core count per task. According to the selected value, Unified should be able to define the memory @X core, right @vlimant? So, we need to change the web form as well as the actor to receive this new parameter. @dabercro @areinsvo

This won't be a problem to add. Do you want it to have discrete options (like 1, 2, 4, or 8 cores, for example) or should I just add a text box?

[dabercro]

I guess another question is do we want this option for 'clone', 'acdc', and 'recovery' or just a subset of those?

For now, I added an options list for all the actions listed above with #80

Hi Dan, the multicore option needs to be available for all the actions. For the moment, I think is better to include the multicore option as a textbox. We can go for 1 to ~64 cores. Now, we need to wait for @areinsvo to include the option at the actor side.

Okay, #81 places them as textboxes

@prozober for the scaling by memory: If both the memory and multicore options are used, actor will assume that the memory value is NOT scaled by the number of cores. Or more specifically, that the memory value passed is for the initial number of cores, and needs to be scaled up to whatever 'multicore' is set to. Does that make sense?

The scaling will be done in the same manner as https://github.com/CMSCompOps/WmAgentScripts/blob/5c0c238562af864091e5a664a4d9d0591e111158/Unified/recoveror.py#L106

The script has been updated and the new feature is ready to be tested. We'll have to pay close attention to it the first couple times the multicore parameter is used.

Hi @areinsvo, that makes sense. I will let you know when I have a request to test.
