And the price pro core does not really increase with core number if you correct for the influence of clock frequency. Dell called it 'saturation' in their benchmarks. In the...

So chances are, while he got interFoam running (which can be daunting at first), he may lack some knowledge of simulation. As...

(As a consumer I would rather just get a very nice used car instead of a Xeon Platinum.) Right now even a lot of server vendors still...

Both run at the same clock rate, both have the same memory configuration. Even under the assumption that the memory bandwidth...

For now they only sell Intel, so the lack of benchmarks might turn out to not be the main issue. They are quoting me various configurations based on Xeon Gold...

Our computationally most intensive cases would be multi-phase simulations using sliding meshes. Since most, if not all, benchmark case come down to single phase flow with an in- and an outlet...

Last friday I asked our hardware vendor to give us quotes for 2x16 systems based on AMD and Intel to get an idea of the difference in price. I assume you would argue that the greater memory...

Unfortunately the extra cost of buying 2 servers, 4 cpus and infiband cards, instead of a single server with one 32-core-CPU is easily quantifiable, while the actual performance benefit is depending...

That brings me back to my original question: Is there a rule to determine the bottleneck? For example four 8-core-CPUs installed in a 4-socket-system will be...
