@andreasnoack could you please test this on any cluster you may have access to and merge?

[andreasnoack]

I've tested with SGE and Slurm which are the managers I've access to. It works so I'll merge. If there are issues with other managers then people can open specific issues. Thanks for fixing this.

What are the versions of Julia on the master and the workers? Are they the same or different?

[bjarthur]

last night's nightly on both. Version 0.5.0-dev+4445

[bjarthur]

nevermind. works fine when running julia on a compute node. problem was that i forgot to qlogin and was on the login node. not sure why that would make a difference. but it works.

interesting though that the "invalid version string" seems to be what is thrown when there is a timeout error.

The wrong error message needs to be fixed. Good catch.
