It is meant to run without much administration costs and complicated cluster safety policies. All nodes where average Desktop computers. It was optimized and tested with Telemac projects divided in up to 40 parallel partitions on 8 computers with 40 cores. The guideline for the development of this disc was: “It shall be a system for quick implementation and faster work flow on small and medium office networks with standard hardware, for demonstration and training purposes”. Tests with 40 cores on 8 Desktop computers showed similar performance as big clusters running on the same number and type of CPU cores:Ī speed up of more then x20 for the MPI parallel computation against serial computation of the official Telemac validation case “221_donau”Ī combined batch processing speedup of x35 for a 1000 job Telemac2d parameter study, compared to single coreįig 1: Parallel performance scaling ability of 150€ gaming CPUs with 1GB-LAN vs. A basic 1-GBit switch is enough for at least 8 computers. Plugging the disks in via USB3.0 or SATA provides good performance.
