Running ED2 as a MPI ensemble #9

Closed Viskari closed 10 years ago

Viskari commented 10 years ago

Hello,

This is actually something that was solved in the earlier version of ED2, but this version has an issue with. So if I run ED2 in DART as an MPI ensemble, where the program is executed by different ensemble members, the ensemble crashes because ED2 automatically tries to run as a MPI program inside another MPI program.

This was solved in the previous version by doing some adjustments to it and then running it with -s after the executable and I was wondering can the same modification be done for the Github version.

This is something I did for when we want to run many ED using mpi to launch those jobs. Will create a pull request for this.

This is there in the master: https://github.com/EDmodel/ED2/blob/master/ED/src/driver/edmain.f90#L97 You should be able to start ED with -s to go in non MPI mode.

Just out of curiosity Ton, when you say DART, is that the programming language dart or something to do with dart radiative transfer?

Thanks for the patch Rob.

The Data Assimilation Testbed (or whatever) not the French RTM!
