Hello,

I am trying to create a ClusterManager for Julia using `blaunch` with [LSF](https://www.ibm.com/support/knowledgecenter/en/SSWRJV/product_welcome_spectrum_lsf.html).

To test running Julia on another machine, I am using:

```julia
blaunch remote.host.name julia test.jl

```

where `remote.host.name` is the host name of the remote machine and `test.jl` is:

```julia
println("hello")

```

However, when I run this I get the following output:

```julia
fatal: error thrown and no exception handler available.
InitError(mod=:Base, error=ArgumentError(msg="Package Sockets not found in current path:
- Run `Pkg.add("Sockets")` to install the Sockets package.
"))

```

Are there any requirements for how Julia is launched? IBM say `blaunch` is a drop in replacement for ssh, so I’m not sure why it doesn’t work.

I have tried running the command with ssh:

```julia
ssh remote.host.name julia test.jl

```

which works as expected.

That is weird.

What does `blaunch julia -e "using Pkg; Pkg.status()"` yield? I looks like it is picking up a different environment between `blaunch` and `ssh`

I get the same error, it looks like it’s failing before any of the code I supply is run.

But I’ve tracked down the difference between executing Julia via `ssh` and `blaunch`.

`ssh` uses `UV_NAMED_PIPE` in ` __init__ ()` while `blaunch` uses `UV_TCP`.

With `UV_TCP`, the code [tries to load the Sockets module](https://github.com/JuliaLang/julia/blame/v1.0.0/base/stream.jl#L236), but the `LOAD_PATH` hasn’t been set yet.

I think this is a bug, so I’ll post on the issue tracker.

have you seen [https://github.com/JuliaParallel/ClusterManagers.jl/pull/74](https://github.com/JuliaParallel/ClusterManagers.jl/pull/74) ? i just started on trying to get it to work under 0.7…
