Two CPU's Richard Hudson4-Oct-05 4:12 Richard Hudson 4-Oct-05 4:12  Please could someone help with the following: I have a PC with 2 processors. I am writing two application in VC++. I want one application to use CPU 1 and the other to use CPU 2. How can I do this in code? Please could someone post some sample code or point me in the right direction. Really appreciate it. Regards Rich Re: Two CPU's David Crow4-Oct-05 4:21 David Crow 4-Oct-05 4:21  I have no idea how to do this, but can only imagine that it would not be a good idea.

Thanks Rich Re: Two CPU's Bob Stanneveld4-Oct-05 7:44 Bob Stanneveld 4-Oct-05 7:44  Hello, I don't think that there is a way to say that your code should execute on a certain processor. The OS will arrange that (and I'm glad that it does ) On VS2005 you can hint the compiler that certain parts of your code can execute on different CPU's simultaiously.

Member 17264404-Oct-05 1:16 Member 1726440 4-Oct-05 1:16  Can anyone tell me how to create a huge 2d array without affecting the processing time too much? I used double pointer to create an array 2d array[27000][27000] as following: BYTE **array; array = (BYTE**)calloc(sizeof(BYTE*), 27000); for (unsigned int index = 0; index < 27000; index) array[index] = (BYTE*)calloc(sizeof(BYTE), 27000); Right now, I need to increase the array size to 54000X54000 or even more. However, the compiler seems to have little problem to compile along with other codes. Even it compiles, the processing time is so slow. Does anyone have a better way to profrom this task? Thanks!

The tigress is here Re: How to create a HUGE 2d array? John M. Drescher4-Oct-05 2:49 John M. Drescher 4-Oct-05 2:49  How much memory does your pc have? Your first array takes over 730MB so if you have less than 1GB of ram it will have to do some swapping which is 10 times slower than memory. Also the second array (54,000 X 54,000) is impossible on a 32 bit windows system as it is almost 3 GB. Also Note: There is a limit (because of the way dlls load) in a 32 bit windows program that is somewhere near 1.2GB. You may extend that if you create compile your program with the largeaddressaware switch turned on (google for details) and boot a capable operating system with the /3GB switch in your boot.ini file.

Prakash Nadar4-Oct-05 5:43 Prakash Nadar 4-Oct-05 5:43  You probably dont need that big an array, depends on the kind of data that you will be working on. May be you need to redesign your implementation so that it works on a small section of the array at a time and rest of the data goes in the array or maybe you need a database. -prakash Re: How to create a HUGE 2d array? Rage_bla4-Oct-05 6:59 Rage_bla 4-Oct-05 6:59  Look into CreateFileMapping/MapViewOfFile - it might allow you create big "arrays". 1 pixel == 1 mil Member 17264404-Oct-05 15:53 Member 1726440 4-Oct-05 15:53  Thanks for all your inputs. The reason for such huge array is storing image information. In other words, 1 array cell equals to 1 pixel and also equals to 1 mil size (may go down to 0.5 mil per pixel). For a size of 54"X54" image, it requires 54000X54000 size of array. With your expertises, there may be another way to work this out. In MFC, there is a CDC class in which have nice functions to draw on a bitmap. Creating such huge bitmap; however, is not possible. Is there a way to make this work? All I need is drawing some figures on a roster, and then retrieving cell by cell whether being occupied with a color or not. I may ask too much but please help if you have some possible solutions.

Of course, I can go through and copy all the required DLLs over manually as the application tells me they are missing, but there must be a better way! Is there a method of finding out what resourses have been used by an application?

It will show you all the dll that your application uses. Re: A required .dll was not found Mike Winter4-Oct-05 0:43 Mike Winter 4-Oct-05 0:43  Thanks for this. I have just fired up dependency walker and it looks like it does exactly what I want! Thanks again Mike
