Description Alexey Shabalin 2022-05-05 23:25:49 MSK
Если это не сильно накладно для использования, прошу обеспечить поддержку до 768 CPU.

  "Find out in this chart of the supported and theoretical limits of the platform. Supported limits reflect the current state of system testing by Red Hat and its partners for mainstream hardware. Supported limits are subject to change as ongoing testing completes."

То есть число "768" это supported limit, за которым надо обращаться в отдел совместимости.

Theoretical limit там указан "[8192]". Это можно включить в ядрах и это не накладно.
