comment Running bits of code in a separate kernel
I haven't had success with this approach, yet, as mma keeps failing on me with irreproducible symptoms (mangled graphics, black graphics, OSX kernel panic, making my entire system unresponsive). However, I will accept this answer as I think it's the closest thing there is to a solution to this problem!

comment Running bits of code in a separate kernel
Thanks for this! Unfortunately running 3D routines in parallel seems to cause a kernel panic on OSX... I guess I could limit the number of kernels.

comment How to evaluate some parts of an expression inside Hold?
I came up with Function[y, Hold[f[x, y]]][y] pretty much immediately after I posted the question. But anyway I think Szabolc's With solution is slightly cleaner. Yes, the thing to replace is always a Symbol, so it's not an exact duplicate of pattern replacement problem.

Perfect! Thanks and apologies for my oversight in looking through the docs.

comment Non-separable partial differential equation in polar coordinates
It seems that NDSolve is sometimes a bit picky when it comes to elliptic equations. Just a quick query: are you sure there is actually a bound state solution for these parameters? I've run Eigensystem on the discretised Schrödinger operator and can't seem to find any sensible solution.

comment Symbol definition in parallel kernels
Also, Association is clearly an appropriate solution here which I will indeed use. However, the question still holds: is there a way to define to a symbol in the way described above from parallel kernels?

comment Symbol definition in parallel kernels
This was exactly what I was looking for before going with the "attching to data" route. Honestly, in my years of using mma I've somehow never come across this rather fundamental built-in. I did try searching for "HashMap in Mathematica" or some such earlier but somehow that yielded nothing useful. Thanks a lot!
