We were happily using PiCloud for several long calculations and we very happy

Now that PiCloud is going away, we ran a few tests on Mutlyvac but so far, we 
are struggling to accomplish the same thing we had on PiCloud.

I have several "pieces" of my puzzle but can't seem to be able to put it 
together. I've seen and tried StarCluster and also various parallel python options but 
all options seem challenging to put together.

The goal is to mimic PiCloud, ie. loop through a function:

def some_NP_func(x, y):
    return z

some_cloud.call(some_NP_func, a1, a2)

Which computes the function on the cloud. We use this often in for loops with 
arrays of arguments. The other scenario is:

some_cloud.map(some_NP_intense_func, [...], [...])

Which iterates through and returns results. We need to run a lot of this in 
batch from a scheduler so I always try to avoid interactive environment (how 
does iPython parallel work in batch?).

IPython parallel works just fine "in batch". As far as your client code (i.e. what you wrote above) is concerned, it's just another library. E.g.
