Main Inventor

Valerio BIOGLIO

Brief explanation

- The patent application is about data encoding and decoding using automorphism-based polar codes.

- Polar codes are designed with frozen bits that support automorphisms described by a binary upper triangular matrix. - Codewords generated using these polar codes can be efficiently decoded using automorphism-based polar decoding. - This decoding method has lower latency compared to conventional decoding algorithms. - The efficiency of automorphism-based polar decoding can be further increased by using automorphisms based on matrix elements arranged above the diagonal in a specific area of the binary upper triangular matrix.

Abstract

The present disclosure relates generally to the field of data encoding and decoding, and particularly to automorphism-based polar encoding and decoding apparatuses and methods, as well as computer program products embodying the method steps in the form of computer codes. More specifically, polar codes are designed such that their frozen bits support automorphisms described by a binary upper triangular matrix having a diagonal including at least one of zeros and units.

- The fan box has multiple communication interfaces, allowing it to be connected to multiple server boards. - The fan box's controller can adjust the fan's rotation speed based on multiple fan box speed adjustment instructions. - This allows the fan box to be controlled by multiple master control nodes. - The fan box is suitable for multi-node server systems without a central management unit and any server system requiring multi-node master control.

Abstract

This application discloses a fan box, a server system, and a method for adjusting a rotation speed of a fan box, and belongs to the field of server heat dissipation technologies. The fan box provided in embodiments of this application has a plurality of communication interfaces, and each communication interface can be electrically connected to one server board. Therefore, the fan box provided in embodiments of this application can be electrically connected to a plurality of server boards. In addition, a controller in the fan box can adjust a rotation speed of a fan based on a plurality of fan box speed adjustment instructions. Therefore, the fan box provided in embodiments of this application can be controlled by a plurality of master control nodes, and is applicable to a multi-node server system with a central management unit-free architecture, and any server system that requires multi-node master control.
