Thank you very much, that indeed solved the problem... 

By the way, that didn't improve the performance of fftw. Dunno what to
think. Maybe I'll examine the source to see if there's some
bottleneck. I noticed that it makes lots of comms between the nodes, but
really a few between the nodes and the server. I think I'll continue to
investigate on the problem in my spare time... If anyone have any idea,
I'd be gratefull.


Again, thank you very much, 

Franz
