Parallel Computing Cluster

Thanks to generous donations of surplus computers from the UNC Charlotte College of Engineering Mosaic Computing Group  we have established a local parallel computing cluster to enable efficient global optimization algorithms for finite element model updating/calibration.  The cluster allows us to run up to 12 simultaneous finite element analyses (through custom developed Matlab code and the SAP2000 OpenAPI Interface library) for parallel optimization techniques, such as genetic algorithm.  Currently, our laboratory computing resources consist of:

1 – Dell Optiplex 990 Workstation – Intel Quad-Core processor with 16.0 GB RAM

4 – Dell Optiplex 780 Workstations – Intel Quad-Core processors with 16.0 GB RAM

1 – Dell Optiplex 745 Workstation – Intel Dual-Core 2.66GHz processors with 5.0 GB RAM

5 – Dell GX620 Workstations – Intel 3.4 GHz Intel Pentium 4 processors with 3.0GB RAM

10 – Dell GX280 Workstations – 3.0GHz Intel Pentium 4 processors with 3.0GB RAM
