چکیده
In the context of preparing an existing Fortran program for parallelization, it is in our experience advantageous to migrate to Fortran90 in order to be able to make use of its dynamic memory management features. However, transforming a well vectorized Fortran77 CFD code into a more flexible Fortran90 program using a hybrid parallelization model still is an adventure. Here we report on our experiences with PANTA, a 3D Navier-Stokes solver that is extensively used in the modeling of turbomachinery. During this ongoing process various software tools are employed: Hewlett Packard's, Silicon Garphics' and Portland Group's autoparallelizing Fortran90 compilers, various serial runtime performance analyzers, Simulog's Foresys Fortran Engineering System in combination with AWK-scripts, Etnus' TotalView parallel debugger, Kuck & Associates' KAP/Pro Toolset for OpenMP and Pallas' Vampir performance analysis tools for MPI programs.

Complete Analysis of Erbium-Doped Fiber Amplifiers Technical Paper
Optical amplifiers make the communication system transparent from the beginning to the end, in contrast to conventional repeater-type systems. This poses new challenges for the performance of all system components, including the optical amplifier. As a consequence, optical amplifiers need to be most thoroughly tested before their deployment. This paper discusses methods and instruments for meas...
