Nick,
That's terrific! Let me know if I can help you find your way around what's there now.
OpenMP could certainly use some attention to add some new features.

Hi

(Cross-posting on ptp-dev and ptp-user since developers and users of PTP might be interested in this)

First let me introduce myself. I'm Nick, a PhD student working with Ralph Johnson in the Software Engineering group at the University of Illinois at Urbana-Champaign. I'm looking at using PTP to implement a set of transformations/refactorings that might be useful for OpenMP developers. Right now, I'm concentrating on implementing transformations (through the LTK refactoring framework) that will reduce/eliminate false sharing. This includes transformations such as splitting scalar[1], expand record[1] and selection of runtime scheduling parameters[2].

What are some other refactorings/transformations that you would like to see implemented? I'm not an OpenMP expert so I would greatly appreciate any suggestions from expert developers on features that could help make their lives easier while working with OpenMP.

I also welcome any other suggestions on other features that you would like to see in PTP for OpenMP. I noticed that the PLDT plug-ins for OpenMP were contributed in 2006 and have been undergoing constant API evolutions to keep up with CDT and the Eclipse platform over the years; however, nothing new has been added. So if you have any other features that you would like, please let me know and I might be able to implement them as well.

Thanks in advance!
