I don't think you are going to have a decent speed-up by just copying to /dev/shm because your 30 GB file probably was probably completely in your OS filesystem cache already, which is memory too. Having said this, in case you get some noticeable speed-up please tell us: I like to hear how wrong I am ;-) -- Francesc Alted _______________________________________________ Hdf-forum is for HDF software users discussion.
