We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Mike, 

We reduced the model to the following: 

28707 nodes and 24,022 elements (of which 23680 are 8-node solid elements with 3 DOF at each node, and the rest are 2-node spring-damper elements). There are also almost 86,000 DOFs and the model is analyzed for 15 sub-steps in time domain. Doing a breakdown of 16/8/4 Core with either No GPU or 1 GPU (A100). The results were the following:

NUM_CPUNUM_GPUElaspsed Time (s)CPU Time (s)
4070236.255
4166222.73
8094609.604
8156368.356
16083761.411
16163631.41

 

Let me know if I’m missing anything else. 

Matt
