✦ Synopsis

We describe a concurrent implementation of the Palermo-Harvard hydrodynainic code on cost-effective and modularly expandable transputer arrays. We have tested the effectiveness of our approach by simulating an already well-studied compact solar-flare model on different transputer configurations and compared their performances with those of other machines. We have found that the speed of the concurrent program on a 16-T800 transputers array is -1/9 of that of the equivalent code optimized for a CRAY X-MP/48. l'his work clearly shows that transputer-based arrays provide locally available high computing-power tools to extend the investigation of compact solar flares and similar astrophysical problems.
