HTCondor requires that we launch the ipengine/ipcontroller scripts rather

HTCondor destroys sys.executable when launching remote processes - a launched

python process depends on sys.executable to effectively evaluate its

module search paths. Without it, regardless of which python interpreter you launch

you will get the to built in module search paths.

We use the ip{cluster, engine, controller} scripts as our executable to circumvent

this - the mechanism of shebanged scripts means that the python binary will be

|
|
launched with argv[0] set to the *location of the ip{cluster, engine, controller}
|

|
scripts on the remote node*. This means you need to take care that:

a. Your remote nodes have their paths configured correctly, with the ipengine and ipcontroller
|

|
of the python environment you wish to execute code in having top precedence.

b. This functionality is untested on Windows.
