Dear all,
sorry for the late notice.
I am in the midst of a proposal deadline and we don't have anything to
discuss urgently, I would cancel for today.
Enjoy the extra hour.
Cheers,

Dear all,
this is a gentle reminder for our call today.
Thursday March 15, 2018 (today)
11:00 am | Eastern Standard Time
Webex Info:
https://apps.fz-juelich.de/scalasca/mpiwg-tools-webex/index.php
Primary goal for this call is to discuss any questions on my short
summary of the face-to-face meeting in my last mail, and to briefly
discuss my idea to promote event sources to 'first-class citizens' to
ease their handling. Thus, it may be a shorter call in general.
Agenda:
-------
- Source handling in MPI_T events
Cheers,
Marc-Andre

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.
Cheers,
Marc-Andre
