ESI Group announces new industrial parallel version of its Finite Element Foundry Simulation Software

ESI Group : 05 April, 2005  (New Product)
ESI Group, leading provider of digital simulation software for prototyping and manufacturing processes, today announced the release of ProCAST 2005, a comprehensive finite element software package for foundry simulation. ProCAST 2005 offers an efficient and accurate solution for a wide range of processes and alloys, from high and low-pressure die casting to sand casting and investment casting. The new DMP (Distributed Memory Parallel) version enables customers to achieve unmatched performance as simulation tasks are distributed amongst several processors running in parallel, at a very competitive cost. The release provides an industrial and highly scalable version on Linux clusters and UNIX multiprocessor platforms.
ESI Group, leading provider of digital simulation software for prototyping and manufacturing processes, today announced the release of ProCAST 2005, a comprehensive finite element software package for foundry simulation. ProCAST 2005 offers an efficient and accurate solution for a wide range of processes and alloys, from high and low-pressure die casting to sand casting and investment casting. The new DMP (Distributed Memory Parallel) version enables customers to achieve unmatched performance as simulation tasks are distributed amongst several processors running in parallel, at a very competitive cost. The release provides an industrial and highly scalable version on Linux clusters and UNIX multiprocessor platforms.

'With parallel processing, even the most complex processes can be simulated overnight allowing foundries to do more mold design iterations in less time', says Dominique Lefebvre, Casting Solutions Product Manager, ESI Group. 'This new DMP version was specifically tuned for small to medium size parallel hardware configurations to deliver high performance at a very competitive cost. Furthermore, the hardware configuration, number of CPU and interconnect switch, can be adapted to meet the end-user requirements in terms of turn around times.'

For optimal scalability, the parallelization of ProCAST 2005 relies on the dynamic domain decomposition technology. Automatically activated in ProCAST 2005, this feature is used to distribute a task on multiple processors. The finite element mesh of the CAD model is partitioned in as many sub-domains as there are processors. To be efficient, the decomposition needs to provide a balanced repartition of the workload and a minimal interface between the different partitions in order to reduce the data exchange between processors. As the casting is gradually filled during the simulation, the load balancing continuously evolves. To maintain optimal scalability, ProCAST 2005 automatically updates the domain decomposition at regular intervals.

The performance of the parallel solver depends on the size of the model, the type of application and system components such as interconnects related to interprocessor communication. Results obtained on a Linux cluster with Gigabit Ethernet interconnect show an acceleration of the speed of analysis up to 6 times for both filling and solidification on 8 processors. Higher scalability can be obtained with more powerful interconnect for up to 32 processors.

The ProCAST 2005 parallel version is available on Linux hardware vendors supported clusters as well as UNIX multiprocessor platforms from IBM and SGI.
