Dear all, I won't make the call today and will have to cancel. Nevertheless, I want to give a short summary of the WG topics at the face-to-face meeting: - Ticket #6: MPIR line numbers has passed its the vote, thus we will soon have to prepare and release MPIR 1.1. - Ticket #77: Integer-based access to MPI_Wtime This sparked an interesting discussion that we should pick up in the next call. While a straw vote showed that the majority likes the fact that the new calls use MPI_Wtime, looking at Jim's measurements on the ticket discussion, I wondered whether an API that enabled the use of the low-overhead counter for our event timestamps would be more beneficial for the interface. - Ticket #67: Consistent reference of MPI process We found a couple more places where we should adapt the text. I will fix this, and this will go up for (a) a no-no vote and (b) potentially a first vote (or another reading) at the next meeting. - Ticket #79: MPI_T events I presented the current proposal and there were no big objections, yet the role of sources was discussed briefly, where I will update the text a bit to enable an easier and more consistent interface to sources in general. I couldn't attend the QMPI discussion, but in the wrap-up, I think Martin concluded that we are also at a point, where we should produce a prototype to see if the API is what we need and want.
