| Abstract: |
The operation of novel phased array based radio telescopes requires vast amount of computational power for the processing of observed data. In the LOFAR telescope, the central on-line and off-line systems will use HPC resources provided by a 1000+ nodes cluster computer. In order to profit from the enormous computational power of this machine an application development framework is built. This framework support the transformation of the current single-node data reduction applications to parallel equivalents that can execute on large clusters. In the online systems, real-time signal processing pipelines can be executed. Furthermore, the complexity of controlling many concurrently running observations and analyses on an inhomogeneous hardware set is tackled. |
