| Ramine <ramine@1.1>: Mar 26 10:18AM -0700 Hello.. Hope you have read my previous post about my USL for Delphi and FreePascal. Please take a look at the source code in the zip file: When you compile the usl.pas , please type this in the command prompt: usl data.csv Here is the output of my program: Peak number is: 449.188 Predicted scalability peak is: 18.434 Coefficient of determination R-squared is: 0.995 The peak number is the peak number of cores (look inside the csv file) that will give the Predicted scalability peak that is: 18.434X I have used a polynomial regression and i have done other approximations to find the predicted scalability peak when the derivative must equal an approximation of 0 and this when the USL coefficient beta equal 0. This is all about mathematics. You can download my USL program from: https://sites.google.com/site/aminer68/universal-scalability-law-for-delphi-and-freepascal Thank you, Amine Moulay Ramdane. |

Why you again post non-topical irrelevancies about your Delphi and FreePascal code that process some csv file? Typically such processing is done in Javascript for to immediately see the resulting graph in browser. If I remeber correctly you promised not to post that again here in comp.lang.c++. We can read the other groups when we are interested. |
1. Design an algorithm to print integers divisible by 3, from 1 to N. N should be input by the user.

Write pseudo code of your solution first. >b. Write the c code for your solution. An algorithm takes two iterators as its first two arguments, so I have to encode N into two iterators in main, and then call my custom algorithm with these two iterators. #include <initializer_list> #include <iostream> #include <ostream> #include <vector> #include <iterator> #include <algorithm> template< class InputIterator > void algorithm( InputIterator first, InputIterator last ) { InputIterator const f{ first }; InputIterator const l{ last }; iota( first, last, 1 ); copy_if ( f, l, ::std::ostream_iterator< int >( ::std::cout, " " ), []( int const i ){ return i % 3 == 0; }); } int main() { int N; ::std::cin >> N; ::std::vector< int >v( N ); algorithm( v.begin(), v.end() ); } |

| Ramine <ramine@1.1>: Mar 26 09:53AM -0700 Hello...... I have just implemented a very powerful tool called USL using mathematics, please read about it here: http://www.perfdynamics.com/Manifesto/USLscalability.html Here it is: Universal Scalability Law (USL) for Delphi and FreePascal version 1.0 Author: Amine Moulay Ramdane. Email: aminer@videotron.ca Description: This program analyzes system performance data with the Universal Scalability Law (USL), and it compiles with Delphi XE versions and FreePascal. You have to supply the performance data as a csv file format, please take a look at the supplied csv file called "data.csv", the first line of the names of the colomuns of the csv file must be commented by "#" character. Just compile the usl.pas program and run it by executing it on the command prompt like this: usl data.csv The Universal Scalability Law (USL) was developed by Dr. Neil J. Gunther. It can be used to analyze system performance data in order to learn more about the scalability limitations of the system. Details are presented in the book *Guerrilla Capacity Planning*. Authors of Universal Scalability Law website: http://www.perfdynamics.com/ You can download it from: https://sites.google.com/site/aminer68/universal-scalability-law-for-delphi-and-freepascal - Platform: Win32 ,Win64,Linux,OSX Thank you, Amine Moulay Ramdane. |
