not sure that in this forum , but the caption of the forum - the optimization of performance.
Hyperthreading significantly reduces performance on calculate-intensive applications (for example linpak ) . Hyperthreading can be disabled in the BIOS, but it's not always convenient.
Hyperthreading can be disabled into offline hyperthreading cores (in cpufreq or in the options of the Linux kernel).
Based on the logic of hyperthreading whether hyperthreading disconnected from Linux have an impact on the HPC applications (like linpack or something else)
I am sorry for possible offtopic
