Here is the list of sense switches and its response for LS-DYNA: sw1 - A restart file is written and LS-DYNA terminates (cluster will shutdown) sw2 - LS-DYNA responds with time and cycle numbers (output in ls-dyna. HPC Clusters Impact of Interconnect on LS-DYNA Cluster Performance. LS-OPT includes capabilities for reliability-based analysis and optimization as well as special features for material calibration (mainly curve matching). I will post examples, show new techniques and some shortcuts for LS-DYNA. Because Dörrer + Broßmann can deliver more precise designs using LS-DYNA than it could. Complementing your Chevrolet Performance crate engine with a factory-engineered new or remanufactured performance transmission is a cinch with our comprehensive lineup of automatic transmissions, torque converters and installation kits. LS-DYNA ® from Livermore Software Technology Corp. Using d3VIEW, you can visualize, mine and analyze the data quickly to enable faster and better decisions. Summary IBM Continues to work with LSTC on improving the performance of LS-DYNA IBM pSeries still provides top performance and the advantages of the AIX user environment IBM xSeries platforms offer a very cost effective Linux Cluster solutions for LS-DYNA customers Users today can customize their system in order to pick the features which serve. To reduce MPP LS-DYNA’s requirement on low latency and high bandwidth on interconnect, LSTC about a year ago began to implement the hybrid method that combines both the shared memory (as in SMP LS-DYNA) and the message passing (as in MPP LS-DYNA) parallelisms.
