[gpaw-users] Can anyone get mpi broadcast working?

[Alex Eftimiades]

I thought it was working about a month ago. Now it does not. I have  
tried testing it with a simple broadcast, and the processes do not  
sync. There is no error, they just do not sync. I am beginning to  
suspect that there is something wrong in the source code since I  
updated between then and now. If not, please show me a working example  
(start to finish) that successfully broadcasts an ndarray with more  
than one element (it does seem to work for one element.)
At the very least, the example provided in the documentation is  
incomplete. I tried copying and pasting it into a .py file and testing  
it. N and mydata need to be initialized with some values. So I  
initialized them with some values. Then I got the same problem as my  
tests--no errors, no syncing.

For now, I may just have to write stuff to a file with one rank and  
load it with the others. However if this is a bug in the source code,  
I would imagine this could cause problems with parallel calculations.

Thanks,
Alex
