One such application is the processing of 3D seismic data. Seismic data sets, consisting of recorded pressure waves, can be very large, sometimes more than a terabyte in size. Even if the computations can be performed in-core, the time required to read the initial seismic data and velocity model and write images is substantial. This paper will discuss our approach in handling the massive I/O requirements of seismic processing and show the performance of our imaging code (Salvo) on the Intel Paragon.} }
