Performance profiling

languages:

  • C
  • C++
  • Python
  • Ruby
  • JavaScript (browser and node.js runtimes)

Algorithms

  • Nilakantha method of determining PI to a specified precision

Running instructions:

  1. Compile C and C++ programs however you want. Sample methods listed below. If you want to profile Python or Ruby, make sure you have them installed.
  2. Open run.bat
  3. Traverse the menus

Input file:

Instead of typing in the same parameters, you can select a file to input the data for you. The contents of the file should be 2 lines:

precision
number of iterations

EX:

12
10

You select the file in the settings menu of run.bat

Output file:

Each time you run a program, it will output the results to a out.part file. In the settings, you can generate a master out.txt file which stitches all the .part files together. If you want to test something specific and don't want all your previous trial history included in the master out file, select the Reset output files option before testing.

Sample compilation:

  • Linux

    • C: gcc nilakantha.c -o nilakantha -lm
    • C++: g++ nilakantha.cpp -o nilakantha

  • Windows

    1. Open in Visual Studio or other GUI and compile
    2. Open Developer Command Prompt for VS
      • cd into the correct directory
      • cl -EHsc nilakantha.c (same with C++)
