Re: [Mpi-22] Fwd: [MPI Forum] #171: change MPI_C_BOOL external32size to 1 byte

8 Sep 2009

      We've used a fairly open model, as long as it is clear what the change  
is.  Typically, this is

The section, page number(s) and line(s) in the MPI 2.2 standard that  
are affected

The text being changed

The replacement text.

See the MPI 2.0 errata for another example.

On MPI 3.0, it is too early to begin this process.  We don't even know  
what chapters are in MPI 3.0; it is not clear that MPI 3.0 should be  
written as an epsilon delta from 2.2; I'd like to see MPI 3.0 written  
as coherent chapters, as we did in MPI 2.0.

A few followups...
1. How is it delineated on the ticket exactly what the errata text is
to be?  I see that you indicated what it precisely is for *this*
ticket, but is there a standard form for indicating *exactly* what the
errata text is for other tickets?
2. Does a separate ticket need to be filed for MPI 3.0, or is it
assumed that the errata change will *also* be applied to the MPI-3.0
latex?  (you may have answered this implicitly via "We *never* change
the document LaTex with an errata vote", but I wanted to be absolutely
100% crystal clear on this point)
Thanks!

We *never* change the document LaTex with an errata vote.  Errata
items are collected into a separate document, which is updated as
items are approved.  The standard consists of the document plus
approved errata items.  This is the same process that was used with
MPI 2.0.  Errata items normally should reference the page/line number
in the relevant document (in this case, the 2.2 document); in this
particular case, the errata was created before the final line and  
page
numbers were available, and the Forum agreed that it was better to  
fix
this through the errata process rather than delay the MPI 2.2
document.  In this particular case, the precise errata item is
In MPI 2.2, on page 433, line 22, change
MPI_C_BOOL 4
to
MPI_C_BOOL 1
I've updated the description to reflect this, as we discussed before
the vote.
Once an item has been voted on twice, I will prepare a PDF containing
these items and add that to the MPI Forum web site as official errata
(again, this is what we did for MPI 2.0).
The process of creating a new version of the document is not part of
the errata process.  Should another version be desired, the errata
should be folded into it.  That is what we did with MPI 2.1.

Comment(by jsquyres):
After a little reflection, I'm a bit unclear on '''exactly''' what
we
voted on for this ticket.
Specifically, is this ticket a request to change the MPI-2.2 latex?
If
so, it is not in the proper form -- it should have the proper
sections for
all tickets.
Or is this a ticket to add a bullet to the not-yet-created MPI-2.2
errata
document?  If so, I don't see clearly delineated what text
'''exactly'''
is going into the new errata document.
To be more clear: I believe that the entire MPI-2.2 errata process
needs
to be laid out.  It seems clear to me that we need ''both'' changes
to the
MPI-2.2 latex (for the 2.3 or 3.0 or whatever the next MPI version
document is) ''and'' a bullet for the MPI-2.2 errata document.  Are
there
supposed to be two tickets; one for each item?  Or should errata
tickets
have text for both documents (line-by-line changes compared to
MPI-2.2
''and'' a bullet item for the MPI-2.2 errata document)?
I understand the urgency of this ticket, but I repeat something that
Bill
said many times in Helsinki: above all else, the process must be
preserved
(in this case: defined!).  Pending clarification to the the MPI-2.2
errata
process, we might need to reset the clock on this ticket.
