I have recently been contracting at the Centre for High Performance Computing. This is just an update on how to map the particular problem I have onto the computing cluster. First steps It is an explanation of how to get to the much easier job of splitting the main task up into bite-sized pieces that can be fed independently via a job submission system called MOAB. Task description Each day satellites MODIS(NASA) and MERIS (ESA) do afew passes of a polar orbit over our region of interest, African coastal andinland waters.
