Re: [OMPI users] revisiting topic: prebuilt on windows7 not xp

Hi,

in http://www.open-mpi.org/community/lists/users/2011/07/16854.php, 
Shiqing says it is impossible to use the prebuilt binaries with 
Windows xp, however I manage to use them in Release mode  with vc2010, 
but not in debug mode.


Can this be some indication that there is a tweak to have both the 
release and debug version of the libs when built on windows 7 work 
also for xp?




Yes, this will be definitely available for the next 1.5 release.

I would definitely rather use prebuilt openmpi libs as it's easier to 
change versions,


thanks,

MM

Re: [OMPI users] Memory mapped memory

[James Dinan]

Sure, this is possible and generally works, although it is not defined
by the MPI standard.  Regular shared memory rules apply: you may have to
add additional memory consistency and/or synchronization calls depending
on your platform to ensure that MPI sees intended data updates.

Best,
 ~Jim.

Re: [OMPI users] Memory mapped memory

[Durga Choudhury]

If the mmap() pages are created with MAP_SHARED, then they should be
sharable with other processes in the same node, isn't it? MPI
processes are just like any other process, aren't they? Will one of
the MPI Gurus please comment?

Durga

Re: [OMPI users] Memory mapped memory

[Gabriele Fatigati]

More in detail,

is it possible use mmap() function from MPI process and sharing these memory
between others processes?

Re: [OMPI users] [OMPI docs] Open MPI compilation Error

[Ralph Castain]

Indeed. However, let me provide this advice. Add --disable-vt to your configure 
line, and drop all the rest of those flags. You don't need what you gave as 
we'll automatically figure those out. VampirTrace isn't happy on Mac, so 
disable it and you should be fine.
