Enforcement Responsibilities 40 | 41 | Community leaders are responsible for clarifying and enforcing our standards of 42 | acceptable behavior and will take appropriate and fair corrective action in 43 | response to any behavior that they deem inappropriate, threatening, offensive, 44 | or harmful. 45 | 46 | Community leaders have the right and responsibility to remove, edit, or reject 47 | comments, commits, code, wiki edits, issues, and other contributions that are 48 | not aligned to this Code of Conduct, and will communicate reasons for moderation 49 | decisions when appropriate. 50 | 51 | ## Scope 52 | 53 | This Code of Conduct applies within all community spaces, and also applies when 54 | an individual is officially representing the community in public spaces. 55 | Examples of representing our community include using an official e-mail address, 56 | posting via an official social media account, or acting as an appointed 57 | representative at an online or offline event. 58 | 59 | ## Enforcement 60 | 61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 62 | reported to the community leaders responsible for enforcement at 63 | https://github.com/walidbosso. 64 | All complaints will be reviewed and investigated promptly and fairly. 65 | 66 | All community leaders are obligated to respect the privacy and security of the 67 | reporter of any incident. 68 | 69 | ## Enforcement Guidelines 70 | 71 | Community leaders will follow these Community Impact Guidelines in determining 72 | the consequences for any action they deem in violation of this Code of Conduct: 73 | 74 | ### 1. Correction 75 | 76 | **Community Impact**: Use of inappropriate language or other behavior deemed 77 | unprofessional or unwelcome in the community. 78 | 79 | **Consequence**: A private, written warning from community leaders, providing 80 | clarity around the nature of the violation and an explanation of why the 81 | behavior was inappropriate. A public apology may be requested. 82 | 83 | ### 2. Warning 84 | 85 | **Community Impact**: A violation through a single incident or series 86 | of actions. 87 | 88 | **Consequence**: A warning with consequences for continued behavior. No 89 | interaction with the people involved, including unsolicited interaction with 90 | those enforcing the Code of Conduct, for a specified period of time. This 91 | includes avoiding interactions in community spaces as well as external channels 92 | like social media. Violating these terms may lead to a temporary or 93 | permanent ban. 94 | 95 | ### 3. Temporary Ban 96 | 97 | **Community Impact**: A serious violation of community standards, including 98 | sustained inappropriate behavior. 99 | 100 | **Consequence**: A temporary ban from any sort of interaction or public 101 | communication with the community for a specified period of time. No public or 102 | private interaction with the people involved, including unsolicited interaction 103 | with those enforcing the Code of Conduct, is allowed during this period. 104 | Violating these terms may lead to a permanent ban. 105 | 106 | ### 4. Permanent Ban 107 | 108 | **Community Impact**: Demonstrating a pattern of violation of community 109 | standards, including sustained inappropriate behavior, harassment of an 110 | individual, or aggression toward or disparagement of classes of individuals. 111 | 112 | **Consequence**: A permanent ban from any sort of public interaction within 113 | the community. 114 | 115 | ## Attribution 116 | 117 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], 118 | version 2.0, available at 119 | https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. 120 | 121 | Community Impact Guidelines were inspired by [Mozilla's code of conduct 122 | enforcement ladder](https://github.com/mozilla/diversity). 123 | 124 | [homepage]: https://www.contributor-covenant.org 125 | 126 | For answers to common questions about this code of conduct, see the FAQ at 127 | https://www.contributor-covenant.org/faq.

24 | 25 | # Java Task Scheduling System 26 | 27 |
28 | 29 | 30 | 31 | 32 | ##
Presentation: 33 | - This project introduces a Java-based Distributed Task Scheduling System for parallel data(Image & Matrix) processing using `Threads`. 34 | - Efficient task scheduling optimizes resource allocation and timeframes. 35 |
36 | 37 | ##
What does my project do exactly: 38 | - Clients can easily submit various tasks like *Filter, Convolution, and Matrix*, executed via `RMI` on the server. All will be executed in parallel. 39 | - Server and its workers further breaks down tasks to pieces and send them through `TCP` to slaves, then compiles outcomes when they are ready again, and then sends the result back to the client. 40 | - Slaves play a pivotal role by executing assigned sub-tasks. 41 | 42 |
43 | 44 | ##
Instructions: 45 | - Fork & Clone the repository. 46 | 47 | - Install JDK if its not installed yet, when done, go to your system environement variables, Edit Path, and add "C:\Path\To\Your\JDK\bin" at the end of it. 48 | 49 | - Put all 5 config.txt files+ image+ kernel.txt in Desktop 50 | 51 | **Inside folder "src" open 8 of Git-Bash in each 1 of type these lines:** 52 |
53 | 54 | ```bash 55 | # Compile Java files 56 | javac Classes/*.java 57 | 58 | # Starts the slaves listening TCP 59 | java Classes.SlaveTask config0.txt 60 | java Classes.SlaveTask config1.txt 61 | java Classes.SlaveTask config2.txt 62 | java Classes.SlaveTask config3.txt 63 | 64 | # Open the RMI port 65 | rmiregistry 13190 66 | 67 | # Start the server, creates multiple workers which works in parallel 68 | java Classes.TaskSchedulerServer config.txt 69 | 70 | # Open the GUI 71 | java Classes.Tasks 72 | ``` 73 |
74 | 75 | ## Extra 76 | ### A port open error: 77 | ```bash 78 | jps #To see all javaprocess along with PID 79 | ``` 80 | ```bash 81 | taskkill /PID 5032 /F #To terminate in case it was needed, 5032 is just an example. 82 | ``` 83 |
84 | 85 | ### More ressources: 86 | 87 | - In case you didn't want to do this manually and felt lazy, check the folder called `Xtra`, I included C codes where it can automatize this work, just fix the Path to each C file in each C code, compile each one of them. When you finish, run **TaskManagement_Process.exe**, this will run all the 8 commands I mentioned above automatically. 88 | - Now whenever you feel like trying the project again just run **TaskManagement_Process.exe**, no need to run 8 commands every single time, consider creating a link to the .exe file instead and add an icon. 89 | - Contact me in [LinkedIn](https://www.linkedin.com/in/walidbosso) for questions. 90 | 91 |
