Re: [ptp-user] Problem with MPICH2 proxy and PTP2.0

[Greg Watson <g.watson@xxxxxxxxxxxx>]

When did you check out this version? The MPICH2 proxy has only been  
updated to work with PTP 2.0 in the last couple of days. If your  
version is any older than Friday, please update your whole workspace  
(including ptp core plugins) and try again.

A few caveats:

- I've only tested it on 1.0.6p1.
- Make sure you have started your mpd(s) before starting the resource  
manager.
- There are also a few issues with the error reporting that I'm still  
working on.

I'm very interested to see if we can get it working for you.
