The number of processors used totally change my code profiling

28 May 2018 by Daniel Pfeffer

A function is typically executed in the context of a single thread. Having additional processors won't improve its speed. Additional processors are useful when your program can be divided into multiple threads. In this case, the more processors, the more threads may be executed simultaneously...

Why explicit parameters for static and dynamic linking

24 Dec 2012 by CPallini

You usually don't pass the whole name of the library (that is complete with its extension), for instance when you link with librt you don't pass directly librt.so or librt.a, but use instead the -lrt switch on command line (please note you do the same thing on Windows, for both dynamic or static...

SEQ Unix / Windows command Sequential Numbers

11 Jul 2015 by Frankie-C

seq is very powerful if used in a *nix environment, you can write on a single console line commands for repetitive actions where an incremental, or sequential, numbering is required.I.e. you can create n files named from 'file0001' on, or ping addresses in a subnet, etc. (Try...

Gnucobol read number with decimal point with

3 Jun 2017 by RAMASWAMY EKAMBARAM

Declaring your variable type as PIC 9(5).99 seems perfectly legal - why should the compiler flag an error! But if you had myvar pic 9(5)V99 the 'V' is only an implied decimal point - variable myvar can hold only digits. Coding: move 147.25 to myvar - this will set myvar to 0014725 and if you...

Why explicit parameters for static and dynamic linking

Hi,I have mostly worked in Windows, and recently I started working in Linux. I have a doubt. I have used Visual Studio as IDE in Windows and used Makefile in Linux.There are two types of libraries in Windows (VC++), static library (.lib) and DLL. It is quite obvious (isn't it?) if I link...

Help with Sudoku code

You need to start gathering information: at present all you have given us is "the program does not proceed" and "apparently the execution halts at solve() function".This isn't a lot - it's like saying "my car won't start" - it isn't enough to solve the problem, which could be anything from a...

The number of processors used totally change my code profiling

Hello everyone! I have one simple question: why the number of processors used when I compile my code with a profiling tool doesn't decrease the time spent in each function? For example, if I compile the first time with 1 processors, and then with four, I expect to see the same flat profile (like...

This is just a matter of counting, as you can see from your example picture. The final line is five stars, the previous line is one space and four stars, etc. So from the pattern it should be easy to calculate how many of each character you need...
