Inside the project, Macintosh, Silicon Graphics and SUN computers have been routinely used for guisdap development. We will continue to use this equipment inside the project, and we will make all the effort to keep the package machine-independent in the future also. In original plans, parallelization of the system was based on the idea of using the T9000 transputers as a development platform. Now that the time to consider buying development platforms for the development of parallel algorithms has come, it seems that the status of T9000 with production difficulties is pretty much the same it was at the time the original project plans were made. This architecture is capable of parallel processing and an 18-CPU parallel computer is actually available for Finnish scientists right now at the Center of Scientific Computing in Finland.
Error estimates at high signal levels.
The most critical point here is to arrive at a development strategy that could be proceed by evolution from the existing software even though we aim at a rather through-going rewrite of the package. These developments may lead to automatic optimization of calculations in cases where the transmitted pulse forms are only through actually sampling them by hardware, for example. It is however possible to gain significant speed improvement by using mex-files in the most critical parts. Both m-file and mex versions work well. The main difference comes from file naming convetions.
