joysanyal21	Hi Christophe, Have you found any possible reason of the error I am getting for running TELEMAC2D in multiple PCs! Any suggestion will be of great help. Thanks, Joy

Could you try from the same place as the network test? (Drive T?) My idea is to be sure that this is not a windows problem. So please make the test successively from the same location with just a change of launcher (local or network). Good luck

joysanyal21	Hi, Thanks for your reply. I tried to lauch the process from the network drive /T in localonly mode using MPI and it worked. I launched the process from different PCs in localonly multiple core mode and it worked. However it still doesn't work on multiple PCs. What should be my next course of action? Joy

Hi Joy

In my opinion, the only things you could try is to add a fortran file to your configuration with the p_init.f subroutine in it (you could find p_init.f in parallel).
In the fortran file, add some writing line to check the configuration of your network. I noticed that the error message with PARAL file allways exist. So you could add some test to try to understand where is the problem. Your listing indicate that the commend INQUIRE(FILE='./PARAL',EXIST=YAPARA)give the value false to YAPARA.
Maybe you could try with only PARAL without "./". the / is Unix like and on windows it's replace by \.

When you run the simulation, a compilation step should occur and if your modification are OK, the simulation should run as previous.
Keep in mind to use -t option to keep the possibility to access to the temp directory.
Check the result of your tests in the slave output file (PExxx.log) and in the master output (on screen)

Good luck

Christophe
