[OH noo, please not that again!](https://www.youtube.com/watch?v=DvShTJKuy2w) Yeah, primes sigh. But they play a minor role here as a perfect victim to explain some other things. Would not advise to use the algorithm here to calculate them in real life. There are languages like Python, F#, Haskell etc. who have list …

A php code sent a query to the database say credentials from login page for verifying and something was returned say TRUE OR FALSE as status. Now my question is, if I do not know the code of the developer who wrote the login form, does there exist any way …

i'm having a problem with my project where i should read the inputs from the status port of a DB-25... Input = Inp(&H379S).... whenever i trigger one of the sensor the value of INPUT will be 135 regardless of which sensor i trigger or even if i simultaneously trigger multiple …

Hello everyone, I'm having problems grasping some concepts of parallel programming; to be more precise, given some pieces of code, I have to determine which of them can be parallel and which cannot(this was in a test in a parallel programming class): a) a=2; b=3; //yes-variables are independently initialised b) …

Hi programmers, I am a c# programmer but I have a very big project in C++ (Which I am not familiar with) and I am facing a big problem. As part of the project, I need to convert the image (any image of any type bmp,jpeg,png...etc) to grayscale using openMP. …

I need help... I want to parallelize the MD5 algorithm using OpenMP in C++.

Hello, I am currently having an issue with a project I am working on. The rest of my project is fine, I am just having an issue with one logical portion of it, and I was hoping someone could help me. I also have to use 1D arrays to solve …

Hello, I am having trouble passing a file into parallel arrays. Based on the code below, I get a bunch of jumbled numbers on my cout screen that don't even show up in the input file. I have attached a PNG of the console output. I am at a loss …

Hi everyone, I'm trying to parallelise a Gram-Schmidt algorithm. Here's the serial code: for( k = 0; k < m; k++ ) { for( i = 0; i < k; i++ ) { s = 0.0; for( j = 0; j < n; j++ ) { s += q[ i …

I am trying to parallelize the [Guibas Stolfi delaunay triangulation](http://goanna.cs.rmit.edu.au/~gl/research/comp_geom/delaunay/delaunay.html) using openmp. There are two things to parallelize here- the mergesort(),which i did and the divide() where I am stuck. I have tried all possible approaches but in vain. The approach followed(divide n conquer) in divide() is same as that …

Hey guys, I am playing with the .NET 4.0's new class Parallel. I tried to open files in a directory and calculate the total bytes of them. However when I run the code, I get a different result every time. Can you explain me the problem I have? [CODE]using System; …

Hello. I have written my code and I am almost done, but I keep getting LNK2019 errors. I'm not sure what I'm doing wrong. Any suggestions? [CODE]#include <iostream> #include <cmath> #include <iomanip> using namespace std; int getStudentCount(void); double getExamScores (int noStudents); double getLabScores(int noStudents); double calculatePointGrades(double, double); char calculateLetterGrades(double); void …

Hi, At the moment I am trying to open a log file with notepad.exe while the original process continues. As I am developing for Windows, fork() is not available for me. I googled alot and found a good reference to opening processes ([url]http://www.yolinux.com/TUTORIALS/ForkExecProcesses.html[/url]), however they all put the original process …

Hi guys. I know this is a long shot, but does anyone know if parallel computing (multiple simultaneous programmers/developers working on the same file) is possible for SQL databases? What I'm wondering if is possible is working on a local database that updates the mdf file in two computers, which …

Hey everybody. All my Google searches for help led me here so I thought I'd post my actual problem directly. I'm in a 101 programming course and this is only our second Python assignment. What I need to do is use one-dimensional parallel arrays to allow input of four different …

Sort of at a dead end, I need to find a way to align an element from Array1 with a specified element from Array 2. I.e. A has the index of 1 and I want it to be aligned with e, How would I go about doing this? I have …

i need a very simple coding of vb6 to control 8 leds connected with parallel port of my on-board parallel port. i need a little description with the coding to understand

Hi there, I have an old Olivetti PR2 Dot printer. This printer was (and nowadays new revisions of this model are) used in bank environment to print on passport books and a4 format sheet. This model in particular has a Parallel port and a serial (25pin) one as well. My …

I don't fully understand what is wrong with my code, it will read the first lines of any text file but then overloads and keeps displaying "0.00" and then crashes the program. I'm trying to get it to read student's last names and read their GPA scores, and the sentinel …

Hi all, I was just wondering if it is possible to use python to send pulses of 5 v (default) through the parallel port. I have made up a circuit board to interpret the pulses, yet this isn't helpful since there are no pulses to receive. Here's some specs( maybe …

Hi everyone! Just wanted to ask before i begin messing around. Is it possible for two processes to access the parallel port simultaneously? So that if i short circuit Input pins to output pins of the parallel port one process will provide input to another one? I am using Windows …

* This program inputs ten integers and * displays the mode using parallel arrays. * Use a method to calculate the mode. This is my specs. I cannot figure out a solution as to how to find the mode using only two arrays. Help would be gratefully appreciated

[ATTACH=left]17191[/ATTACH]Today at Intel's IDF 2010 was the official launch of the 2011 version of Intel Parallel Studio. Parallel Studio is a set of tools that enhance Visual Studio to support full parallel programming. This is more than just a simple plug-in for Visual Studio. It's an entire set of tools …

[ATTACH=RIGHT]17350[/ATTACH]Since the release of the second edition of Parallel Studio this month, I've spent a good amount of time with it, trying out the new features. First, what's Parallel Studio? It's an add-in for Microsoft Visual Studio that gives you a large set of features for writing parallel code that …

Could someone please advise me on how to implement fork() in a parallel processing (multiplying) of a 2d array....I have been at this for far too long.. here is my code [code] for (int i = 0; i < rowCol[0]; i++ ) result[i] = (float*)malloc ( rowCol[1] * sizeof(float) ); …

Thought you were bleeding edge with your quad-core PC? Think again. A company called Tilera today announced that it's working on a chip containing 100 processor cores, which it says could be seen by 2011. It's part of its new TILE-Gx line of 64-bit multi-core processors, the first of which--a …

The meaning of parallel is not that of parallel processing. I simply mean that if algorithms A and B are represented by the two sequence of operations (a_1, a_2, ...) and (b_1, b_2, ...), then the executed sequence of operations is (a_1, b_1, a_2, b_2, ...). It is not compulsory …
