RT-BOINC stands for a Real-Time BOINC It was designed for managing highly-interactive, short-term, and massively-parallel real-time applications. We designed and implemented RT-BOINC on top of BOINC server source codes. Contact information: Sangho Yi and Derrick Kondo |

Why did we need to modify PHP codes?
|
The original BOINC uses both PHP and C codes to retrieve the main MySQL database,
because the main interface between BOINC server and hosts is CGI-web.
When a user wants to create account, it goes to create_account.php, and the PHP codes
retrieve if the account is already existing in MySQL database (select * from user where ... SQL).
Then, the PHP codes make a new account on the database. However, in RT-BOINC, we don't use the MySQL database, but use the shared memory segment IPC. For this reason, we modified several PHP codes which are essential for workunit distribution and reporting. |

Using exec() and system() style 'command execution' function in PHP codes: We modified PHP codes to execute the native programs written in C language. - in html/user/create_account.php, and html/user/lookup_account.php - in some other PHP code files also Implementing native programs for retrieving the 'shared memory segment': We implemented new native program codes in C language for each PHP action. By doing this, RT-BOINC can support 'on-the-web' queries without problems. - in sched/php_create_account.cpp, sched/php_lookup_account.cpp Notes for developers: We still have to modify the non-essential PHP codes. It's not a big deal, but a time-consuming work. |
