SGE: is it possible to access a sge cluster with julia from outside ?

[samusz]

The cluster facility I have access to has Julia v0.5 at the moment.

Since I'd rather not have to worry with version compatibility is it possible to use this "cluster power" from another julia process (eg from my laptop) ?
I mostly FFTs calculations (sound analysis).

You have to install the same Julia version on the Cluster. You can change which version of Julia is being started, but it has to be the same one accross the system

Is there a way to just use the cluster to send requests from my laptop's julia directly ? (in R there's a qsub package that does that : https://cran.r-project.org/web/packages/qsub/index.html, not sure if it should work with RCall, I had no success)

[vchuravy]

I don't know hoe the R package does that, but as long as you have qsub installed we should be able to do something similar.

The only caveat is that we currently expect a shared file-system, but it might be feasible to relax that. Contributions are always welcomed!

I believe I have found it in the Distributed.jl package :
(from the doc https://docs.julialang.org/en/v1/stdlib/Distributed/#Distributed-Computing-1 )
addprocs(manager::ClusterManager; kwargs...) -> List of process identifiers
Launches worker processes via the specified cluster manager.
or may be
addprocs(machines; tunnel=false, sshflags=``, max_parallel=10, kwargs...) -> List of process identifiers
Add processes on remote machines via SSH. Requires julia to be installed in the same location on each node, or to be available via a shared file system.

I'll try to make it work. A bit confused now as to why there is 2 functions.
Thanks again for your help @vchuravy
