Hi Folks, I've got, at this point, a rather ill-defined requirement that I thought I'd run by you. I thought about posting on the off-topic list, but this is a real world task that I hope SuSE is up to. The problem takes a volume of water that can be represented as a three-axis array. The X and Y directions have a modulus of 500, the Z 20. We then need to access this volume by specifying any two X,Y,Z points to extract data that represents acoustic transmission loss between the specified points. The data returned would be a vector of sound amplitudes and time delays. An array of frequency vs transmission loss might also be required for each point. The number of elements for a fully populated array is huge (2.5e+13). There are ways to reduce the number of elements, maybe by the sources being in a smaller patch than the receivers. It might also be possible to use a polar grid about each source coordinate with perhaps 50 radials. It's thought that the total array size could be pared to 10-TB or less. Do any of you have any thoughts about how we could set this up? A database? A file structure using HDF5 or NetCDF? The programming language of choice is FORTRAN, but anything that makes sense could be used. Do you think this kind of problem could be hosted on anything affordable by a small company (~$30,000)? I know it's rather an ill-defined problem at this point, but I'd guess that HDF5 would make the most sense.
