Re: [Fab-user] Fabric Parallelization... Very Confused

[Stephen Rosen]

As a point of curiosity following up on this, will Fabric 2.0 also use multiprocessing? I know the plan is to use env to pass data between processes, but that suggests to me that all access to env will be protected by a Big Fat lock. Multithreading as an option would let users rely on lighter weight synchronization.

Also, is there a place where the roadmap for Fabric 2.0 is laid out? I'm just wondering what Mr. Forcier's Master Plan involves.

Hi Eric;

I am sorry, I do not understand your reply.  Is there an optiion other than -P that I should use for parallel/multi-thread execution?

The multiprocessing module provides an interface similar to the threading module, but using subprocesses rather than threads to create workers.  So, no, fabric does not support multi-threaded parallelization, it supports multi-process parallelization.

Hello Everyone;

I just found this in the 1.6 documentation and I am very confused.  Dose this mean that Fabric does NOT support multi-threaded parallelization, despite the presence of the -P option?

I believe it uses the multiprocessing module for parallel execution.
