Embodiment Construction

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without making creative efforts.

[0035] QAT (QuickAssist Technology) focuses on data security and compression acceleration to help improve data center performance. It is a hardware and software architecture technology that allows seamless integration within the IA architecture and the use of third-party coprocessors. From the hardware level, the QuickAssist architecture allows third-party processors to be installed on Intel's processor sockets. By being manufactured in the form of FPGA Accelerator Hardware modules (AHMs), third-party coprocessors can be ...

Abstract

The invention provides an OpenSSL-based QAT performance comparison method and system. The method comprises the steps of installing a QAT driver, OpenSSL and qat-engine; loading USDM; running lsmod; checking whether the USDM component is successfully loaded or not; creating a qat-engine environment of the OpenSSL; and comparing algorithm speeds of the qat-engine and the OpenSSL to obtain performance comparison data. QAT and SW are loaded for verifying the speed of the same encryption algorithm; the operation is simple; the test manpower is reduced; a test result is simple and clear; an obtainedconclusion can serve as data support of QAT technology promotion and reference for measuring the technical development quality by test personnel; and the test systems and dimensions of the QAT are enriched.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an OpenSSL-based QAT performance comparison method and system. Background technique [0002] In cloud computing, the importance of security is increasing day by day, and the security level is constantly improving. It is necessary to invest a large amount of computing resources to handle complex calculations of encryption and decryption. Using general-purpose chips to handle encryption and decryption calculations will increase the cost of cloud computing centers. QAT, which adopts special encryption and decryption technology, solves this bottleneck for users. [0003] Since data compression is a computationally intensive task, enabling compression usually significantly increases CPU overhead. Using QAT can transparently compress / decompress data without increasing CPU overhead, so as to achieve the goal of saving disk space and disk read and write bandwidth, and increasing disk re...
