I am trying to run cosmomc with MPI. When I run it on for example n nodes, I should get n chains let's say test_1.txt to test_n.txt but all the data is written into only one file : test_1.txt.

Any body can help ?

Thanks

I seem to have a similar issue (http://cosmocoffee.info/viewtopic.php?t=1273), running over multiple cpu's, but only getting one test_1.txt file. Anyone know what's wrong?
