Kunpeng devkit & boostkit

a devkit

1 Business: Start, test, deploy, migrate, monitor projects in different environments

2 Requirements: x86 server, x86 processor, complex instruction set migrated to Kunpeng server, Kunpeng processor, concise instruction set

3 Solutions:

(1) Feature "set":

1. Development
   1. Code Migration Tool
   2. Kunpeng Development Framework
   3. Efficient migration, minimal development

2. Compile and debug

   1. Compile and debug plugin

   2. Kunpeng has higher affinity performance

3. Compile and debug

   1. Compile and debug plugin

   2. Kunpeng has higher affinity performance

4. Tuning & Diagnostics

   1. Performance Analysis Tools

   2. Comprehensive analysis, accurate diagnosis

(2) "God" refrigerator: Kunpeng one-stop full-process development kit devkit

4 Complete the study

(1) System organization, principle, process

(2) Heavy: Migration

1. Analyze Scan
   1. Know the workload (time) of the migration job
   2. How many files need to be modified
   3. Which dependencies are required
2. Source code migration
   1. Quick scan for frequently used languages
   2. For a language, scan the differences between two different instruction set architectures
   3. Comparison:
      1. devkit: Provides modification and optimization suggestions, and even one-click replacement
      2. From work: I can't find all the differences, and I don't know how to change them
   4. The rest is to compile the code, and the project can be turned into software suitable for the Kunpeng server.
3. Package refactoring: for package mode
   1. Scan x86 dependent packages (such as rpm packages, jar packages)
   2. One-click reconstruction, you can modify the package under x86 into a package suitable for Kunpeng
   3. Get the modified package, you can install it on the Kunpeng server and run the project.
4. Special software migration: for some special projects (big data, web, cross-performance computing software and other types of projects)
   1. Community download package
   2. One-keyboard compilation and migration based on the Kunpeng mode to get a package suitable for the Kunpeng server

(3) Heavy: Acceleration Library

1. After switching to the Kunpeng server (ARM, simple instruction set), there is a means to quickly improve the performance of the software immediately.
2. Kunpeng acceleration library, free acceleration for some commonly used packages, libraries and software.
3. How to use: After using the Kunpeng acceleration library, etc., you can immediately and quickly improve the performance of the software.

(4) Heavy: Compile

1. 3 compilers to ensure good performance on Kunpeng
2. Lifetime Compiler: LLVM
3. Biyi JDK: based on open jdk
4. Kunpeng GCC: GCC Development

(5) Heavy: Tuning (Performance Analysis)

1. Like the above "acceleration library, compiler", it will be effective immediately after adding the corresponding tool (library).
2. Tune is a tool to dynamically analyze and improve the performance of hardware and software.
3. System performance optimization: Collect processor and hardware performance indicators.Graphical.Optimization suggestions.3 modules with 8 functions.
4. JAVA performance optimization: java virtual machine tuning (GC, heap, thread lock).

(6) Outline: ExaGear: Complete the rapid migration of x86 source-free applications at low cost.

1. No source code
2. The source code of the old version of the software cannot be found.

Two boostkit

Three other

1. Get linux OS details:

   1. cat /etc/os-release

   2. cat /etc/redhat-release

2. View CPU architecture: arch

Cluster and Architecture: (1) Logic (2) Physics (3) 11
Self-understanding:
Close: [Association, Comparison]
Doubt: [Doubt, such as preview, workQuestions]
Heavy: [thoughts, ideas, implementation techniques, tools]
Difficulty: [feelings, experiences, comprehension] [summary, induction, rules]
Avenue to simplicity: outline (systematization, breadth, at least the video title) chart short
