Knowing the use of CPU / memory

[ISAIAH]

Hello
My question is simple enough regulars Linux, a bit less for a novice like me. I am running a C program to capture video (stream), and I know from the CPU and RAM by the program during its execution. Does any one know what is the command for doing the same. I am in a Mandriva Free 2007, Gnome 2.16. any help will be highly appreciated. Thanks in advance.

Hello,
In the Command line, you can use:

top

You can also configure to see the data you need. Makes a man top for more information Otherwise, by default, I think Mandriva should include a program monitoring system, looking through menus, it should exist ... But personally, top suits me perfectly.

Hello,
I also want to know the command used for the same, by cons I have a question, the resources required by a program they are exported from one system to another? Let me explain ... I'll have to implement this program on an embedded card, the resources listed on my PC they are used (for information) to scale the CPU and RAM necessary any map? Any help or explanation on this. Thanks in advance and waiting for the reply.

Hi,
No unfortunately I do not think the CPU or memory usage are representative of those that you have on your card onboard. They are indeed dependent on your system, management RAM / Cache kernel and processor of your machine. It is still a good indication. Know that depending on the program, it can use more or less memory on different environments, many things can come into account. Your application is what kind? Have you a way to emulate your card embedded on your pc? If yes, use it to evaluate your application directly to an emulated environment, it will be more meaningful.

Hey,
Well, actually the crux of the problem is here, this is a project within a school, with an club, I developed a solution for the video with the help of streaming, and now it is to find the platform receiving and convincing to be allowed to buy components and the question is simple, knowing that I have a VERY limited budget what is the best solution for this. So, I have being trying a different types of variations.

Hello,
A large number of process runs continuously on your machine. Some are more important than others and some consumers are more resources (RAM, CPU ...). As you all know, all this information is available via the top command.

$ Top

But if you still use the top command, you has been. There are now proposing a similar color, and most importantly, the ability to scroll easily (with arrows) in the process list.

# Install the package htop if necessary
$ Htop

Apart from this practical side, htop provides substantially the same information as top.
