Hello dear starcd-colleagues!
As the subject states, how do I manually merge a pst-file from a parallel run? The automatic merge of the pstt and pst-files failed due to the pstt-file being to large (2 GB on each node... my bad...) In version 3150A there existed a command to do this but I can't seem to find a similair command in v3240, which is what I'm using. Hope anyone of you can help me. Kind regards DrA |

The following command: $STAR/bin/mergepst will do the trick (make sure that you have sourced your STAR intallation before).

Yes, that's right. In the new starcd version v3.2x mergepst and mergepstt are no longer in the environment path, but still there (start a search: find /usr/starcd -name "mergepst*")
mergepstt will fail again when you ty it manually, because of the 2GB limitation on 32bit machines. I do it this way: - use the "Backup Frequency" in NavCenter for every wanted timestep intervall (e.g. every 5 timesteps). Star writes out a <case>.pst_xxxx (xxxx=timestep) file in each cpu-domain. - use the mergepst binary to merge this domain-<case>.pst_xxxx-file together timestep for timestep. (Be sure to use the new mergepst, and NOT that one of v3150A !!!) Possibly you become a little mad for this job. You can write a small c-shell script, containing a loop (over all wanted timesteps) doing that for you (use "if" and "goto" commands). With this method you can run millions of cells and many many thousends timestep without getting a problem with 2GB. |
