"Dual Core" vs "Hyperthread" CPU technology in CAE analysis?
(OP)
Hi !
I want to buy new machine for CAE analysis. Although I studied a lot about the "Dual Core" and "Hyperthread" CPU technology, I'm still not sure which is better for the solving perpormance.
Please, let me know your advice about the problem.
Thanks in advance.

Anyone interested in the technical side of the processor issue should go to the CPU part of Tom's Hardware. They have some interesting benchmarks also.

that ABAQUS is expected to perform on multiple-core processors, similarly to on multiple single-core processors.
Anyway ,in order to take advantage of dual-core CPU you need additional license to enable parallel processing capabilities. From licesing point of view, ABAQUS sees each core as a separate processor.
From my personal experience, we have machines with single hyper-threading enable processor, with single dual-core and 2 single-core processors. The machines have comparable hardware characteristics (~3.2 GHz, 2 Gb RAM). The licensing does not enable parallel processing and the performance obtained among the machines is comparable if you run a single analysis. If you run 2 independent analyses, the machines with dual-core and 2 single-core processors perform much better.
You sould check I-DEAS support site for similar informations.

to take the full advantage of current S/W capabilities.
Thanks, mrMikee and xerf for kind answers.
