Dear all,

I have a question, can I directly run parallel file on my editor Notepad++ instead of using mpiexec command on my CMD terminal. Since I can directly run sequential file on Notepad++. But for parallel file, it will report an error like the following:

Error line number 1047, in file macro: buildOverlapEdgePeriodicRecursive in C:\Program Files (x86)\FreeFem++\idp\macro\_ddm.idp, before token mpiWtime

current line = 1047  
Compile error :  
line number :1047, mpiWtime  
error Compile error :  
line number :1047, mpiWtime  
code = 1 mpirank: 0  
WARNING! There are options you set that were not used!  
WARNING! could be spelling mistake, etc!  
There is one unused database option. It is:  
Option left: name:-wait (no value) source: command line  
try getConsole C:\Program Files (x86)\FreeFem++\examples\hpddm\advection-TS-2d-PETSc.edp  
save log in : ‘C:\Program Files (x86)\FreeFem++\examples\hpddm\advection-TS-2d-PETSc.log’  
wait enter ?

Looking forward to your reply.

Best wishes,  
Xuan

You need to invoke `FreeFem++-mpi` or `ff-mpirun`, not `FreeFem++`.
