It sounds ok to try out. A clear distinction between what the MPI standard means when it refers to faults, errors, and erroneous programs might be a useful clarification (since even with the RTS proposal an application can still be erroneous if they do not heed the semantic requirements of MPI). I'm a little concerned about adding something that significant to the RTS proposal this close to the deadline. In particular, I think we might need to discuss the changes that you propose before committing to them. So I would suggest that you fork the ft-wg RTS proposal in the SVN repository and make the changes there (I think you have permissions to do that, if not let me know and we'll sort it out). Then once it is ready we can review the changes and decide if we want to merge them in now, later, or push to the future. Merging them back in shouldn't be too difficult if we like what we see, but pulling them out if we cannot agree before the deadline might be more difficult. The absolute final day for the RTS proposal is July 4. Since that is a US holiday, I intend on sending out the RTS proposal next Thursday (June 30). So my hope is that Wed. June 29 on the teleconf we are making the final edits before it goes out the door. -- Josh On Thu, Jun 23, 2011 at 7:40 PM, Bronevetsky, Greg <[email protected]> wrote:
I don't know if we need to. It sounds like this is too much detail for the type of change that Darius is proposing. It sounds good to me.

How will you distinguish between an error that is the result of a bad parameter and a "detected fault" ?

I feel it would be easier to explain/understand FT related things if we distinguished between errors and faults, i.e., an error is a detected fault. �I'd like to take a stab at running through the whole standard to make these changes. �But before I spend time on this I'd like to make sure people are OK with it.
I believe I'd have to be done with this by Wednesday. �(right Josh?)
Does anyone have objections?
