best practice for performance #27
Comments

I am using Taichi v1.7.1 and removed dynamic_index parameter in ti.init() |

I think the performance depends on geometry (will affect data continuity in
memory), configuration of your computer (software and hardware), your
library versions etc. I think as these configurations are not the same, so
we got different results.

Hi, I am trying to verify the performance on an A100 PCIe version.
However, I can't get the expected performance reported in your paper.
Currently I am getting 467 MLUPs for cavity example with 400^3 cubic and
86 MLUPs for non-sparse case for 2phase with 256^3.
Besides, in your paper, it is reported that *"The performance of the
NVIDIA A100 GPU reached over 900 MLUPS for single-phase flow and 500 for
two-phase flow with surface tension."* in conclusion section. However in
table 1, the max MLUPs for 2-phase is 310. Is this typo or other reasons?

so what's your suggested best practice to achieve good performance?

Sorry I'm not the best person to answer this question I'm afraid. I'm not a
computing export, but a researcher working on CFD algorithm subjects, more
on the numerical methods side...
