 MPH_global_proc_id()= 8
  sum of local ranks in cpl is  0
  sum of global ranks in cpl is  8
  sum of global ranks in world is  36
 I am cpl 0 (g=8), recv from ccm 1 (g=7)
 I am cpl 0, expect a2c(1)=100
 cpl 0 gets a2c(1)= 100
 I am cpl 0 (g=8), send to pop 5 (g=5)
 cpl 0 sent to pop 5 successfully
 myProc_joined= 0
  sum of joined ranks in cpl_pop is  21
 I am proc  8  of global,                   proc  0  of coupler
