how to run local[k] threads on a single core

[sujeet jog]

Is there a way we can run multiple tasks concurrently on a single core in
local mode.

for ex :- i have 5 partition ~ 5 tasks, and only a single core , i want
these tasks to run concurrently, and specifiy them to use /run on a single
core.

The machine itself is say 4 core, but i want to utilize only 1 core out of
it,.

Is it possible ?

Thanks,
Sujeet
