Subject: Re: [OMPI devel] SHMEM symmetric objects in shared libraries
From: Joshua Ladd (jladd.mlnx_at_[hidden])

Are you claiming that in the following test, the static variable "val" will
not be seen as a symmetric object?

#include "shmem.h"

int main( int argc, char **argv){
    long my_pe, npes, master;

    start_pes(0);
    my_pe = shmem_my_pe();
    npes = shmem_n_pes();

    master = npes - 1;

   /* only used on master */
   static long val = 0;

   if(my_pe != master ){
       shmem_long_fadd(&val,1,master);
   }

   shmem_barrier_all();

  return 0;
}
