Hi! I am looking for an AI that can produce publishable illustrations from drawings/sketches. I am working in scientific research, and I have to produce images illustrating various things for my papers. Doing this to high quality is very time-consuming. I would rather just do a simple sketch...

Thanks for the input. My thought was also that it would be a memory leak. After some reading, and thinking, I realized what the problem is: diagVertex is an inherited class of type diagElement. In some instances, the pointer to v is of type diagElement. When calling the destructor, the call is...

Hi I have encountered a strange behavior of my c++ code when calling a destructor. Basically, I do the following: I have a pointer to an object v of type diagVertex. Then I delete it: delete v; v=NULL; This should call the destructor of diagVertex: diagVertex::~diagVertex() {...

Actually, I did not test that approach. MPI is very well designed and incredibly stable (though I know nothing about how it actually works), and I would not be surprised if it did work. However, it strikes me as a bad idea to implement it this way. Whats not to say that it would work for 4k...

Hi all Sorry for being a prick. Somehow I managed to forget about this post that I made, and I did not see the replies until now. I have had a bit to much work to do lately. Shame on me. So, long story short: I managed to solve this problem by changing the structure of the communication...

Hi I am writing an application that will use MPI and a large number of processes-- up to 4096 or so. At a certain stage all processes except rank=0 should send some result to process zero. Is there an issue with stability if thousands of processes try to send messages more or less at the same...

Thanks everyone. Ill ask the bank, and if not possible I will have it sent over seas and use the app. Thanks for pointing that out to me. I will be gone for a long time and I need the money...

Hi I am expecting a check from my employer, but I will be traveling. Can I have a coworker cash that check into my bank account? Im using bank of america. Thanks // Johan

Hi, thanks for the replies... So I only need to write to the array, not read from it. It appears to me that WM_copy is a microsoft/windows thing? I will be using a linux cluster for this... And no I don't want to store multiple instances of the data. Memory may be cheap but for this...

Hi all, I am developing a simulation tool for a physics problem that I am working on (using c++). Essentially, the computation consists of manipulation of pointer structures that correspond to different physical processes. The output is “events” in time and space, and needs to be stored on a...

Great! Thanks!

Hi I am implementing a data structure that consists of a large network of nodes with pointers between them. I am memory bound, so I like to reduce the memory footprint. These nodes are all of the same class. Now, the nodes have some data fields that cost memory. I consider replacing the...

Oh thats a typo. IR=2 and nothing else. Sorry

Hi Im passing some multidimensional al arrays over MPI. However, Im struggling with some hangups. Essentially I do static cont int NK=16 static cont int NT=400 static cont int NK=S=4 static cont int NK=IR=2 double SIGMA [NK][NK][NT][S][IR]; ... cout<< MPI_RANK<< " begin...

Thank you all for your input. I think a good starting point is to read the referred guide. Perhaps I can do some small scale experiments on some select problem to see what happens. Thanks a lot // Carlis
