Hi

For a project to run, one should be calculating the system requirements. I want to know, is there any formula to calculate the System Requirement of any software project. like the processer, RAM etc

That's a excelent question, I usualy try it on a few system, and give out the approximate time for a particular operation on each system, then I calculate which one is apceptable, which one barelly work, and which is the best optimized. And I end up give all three in the documentation that goes with the software.

Well... depending on what all the program does...

In like NT (or the others if you can get the memory used by the program...)
You can run the program, open everything up that it can do, if you have calculations that take a while, run that. then check to see how much memory it takes, then add like 10-20% to it (rounding to the nearest MB, like 16, 24, 32, 48, 64, 92, 128)

Likewise for speed stuff... if it doesn't really do anything complex, just accessing a database and doing simple queries (SELECT * FROM tablename) and not joins, unions, etc... a simple Pentium-150 (non-mmx, not PII or greater, just a P-150) can do that type of stuff in a few seconds to about 20... although most things anymore it'd be probably safe & easy to list a PII400 as the min processor - since most people would already have that, and just put a notation that others may be able to work also, just not have the speed they desire.

hi

thanx for the reply. actually i have attended an interview. this was the same question that was put before me. now i am making it somewhat clear. the interviewer asked me, is there any software engineering formula to calculate the overall system requirement, even if the system load for that particular software is up to a maximum (even the system uses most of the resources).

I do not know if they are a actual formula, even though I pretty sure someone must have come up with one.

When I used to do animation in Assembler, we used to calculate in CPU clik, Trying to find out how mush CPU usage a particular sub may have.

So I guess that starting with this process, you may be able to compare with a CPU power, and the derire process time, that might give you the result for the CPU speed.

In the requirement, If your using procedure from DirectX ver X, you might want to specified with Graphic card are compatible with the Version of Direct X.
