Re: [OMPI users] error on dlopen

2016-11-03 Thread Gilles Gouaillardet


Mahmood,


did you build Open MPI as a static only library ?


i guess the -ldl position is wrong. your link command line should be

mpifort -O3 -o xCbtest blacstest.o btprim.o tools.o Cbt.o 
../../libscalapack.a -ldl



you can manually

mpifort -O3 -o xCbtest --showme blacstest.o btprim.o tools.o Cbt.o 
../../libscalapack.a -ldl



it should show -ldl is added *after* -lopen-pal


Cheers,

Gilles

Re: [OMPI users] Slurm binding not propagated to MPI jobs

Getting that support into 2.1 would be terrific -- and might save
  us from having to write some Slurm prolog scripts to effect that.

Thanks Ralph!

  Ah crumby!! We already solved this on master, but it cannot be
  backported to the 1.10 series without considerable pain. For some

  reinstated there (probably not until 2.1).
  
  
  Can you manage until then? I think the v2 RMâ€™s are
thinking Dec/Jan for 2.1.

All right, letâ€™s suppose we look for

* if it includes the word â€œnoneâ€,
  then we know the user specified that they donâ€™t
  want us to bind
  
  
 
  
  
* if it includes the word mask_cpu, then
  we have to check the value of that option.
  
  
 
  
  

  * If it is all Fâ€™s, then they
didnâ€™t specify a binding and we should do our
thing.


   


  * If it is anything else, then we
assume they _did_ specify a binding, and we
leave it alone

  
  
 
  
  
Would that make sense? Is there anything

In https://www.mail-archive.com/users@lists.open-mpi.org/msg30229.html, I 
referred to the --enable-mca-no-build configure option.  From "./configure 
--help":

  --enable-mca-no-build=LIST
  Comma-separated list of - pairs
  that will not be built. Example:
  "--enable-mca-no-build=maffinity,btl-portals" will
