These are modal frequency response runs where many modes are needed. Observations on GPU performance: Using GPU computing can help reduce run time for certain problems.
The settings are also designed to keep users from asking for too much resource which leads to performance issues.
In case you had not noticed there were some pretty significant changes there to help users take better advantage of machines with more memory. I have also been happy with new config file (.rcf) settings that started with NX Nastran 10.0. In the general information category, it appears NX Nastran 10.2 is about 10% faster than version 10.0 for standard modal dynamics solutions. My graphics card is an AMD Firepro W9100 with 16GB. It has a 1TB hybrid drive, a 512GB SSD drive and we just added a new 256GB PCIe SSD drive. My desktop is a Dell T3600 with dual quad core Xenon processors and 64 GB of RAM. I was particularly interested in new technolgies like GPU processing and also a new style disk drive (PCIe SSD) which we added to my desktop machine. I have been doing a little performance testing in the latest release of NX Nastran (10.2) which is included in the newest Femap release just announced (version 11.2.1) and I thought I would share a few things that I have learned in the process.
