Picking a proper parallel library

[henry2004y]

Hello,

It is nice to see that the manual is becoming more and more comprehensive with time!

However, the section of mentioning other parallel libraries makes me wonder about how to select a parallel library to use in practice. There have been already ~10 libraries aiming at better usage of either multi-threading or multi-core parallelism besides the basic ones mentioned in Julia's official document; many of them provide more or less the same functionalities, which makes it somehow harder for users to choose from. Maybe this is also a sign that many more can be done in this category, and eventually one package will show up.

What is your opinion about this? Will there be a standard MPI or OpenMP like library in Julia? In the future if I want to build a massively parallel project using Julia, a good parallel library will be a solid building block. I know you are also an active developer in this field, so it is good to hear from an expert!
