    AI for editing illustrations

    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...

    Question C++ weird destructor behavior.

    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...

    Question C++ weird destructor behavior.

    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() {...

    MPI-- many calls to same process and stability

    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...

    MPI-- many calls to same process and stability

    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...

    MPI-- many calls to same process and stability

    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...

    Share memory parallelisation with independent processes but shared output data in c++

    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...

    Share memory parallelisation with independent processes but shared output data in c++

    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...

    Mmemory usage of function in object in c++

    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...

    Does antimatter weigh more than matter?

    Antimatter has the same mass as matter. The same set of particles with the same energy ect. Thus, you can construct the same stuff from antimatter as from matter. But all electric charges are opposite.

    MPI vs MPI and open MP

    I am wondering about the performance of MPI ans open mp. If I use MPI and run a program on shared memory, will the performance be much worse than if I would use omp? And if I use MPI to run it on multiple server nodes, is there any gain in parallelizing using omp within the server node...

    AMD Bulldozer as server and HPC

    Explosion in central Oslo, Norwegian Primeminister's Office was hit.

    The government now says there was only one detonation. Yes I would expect Denmark to be a more likely target, having participated in the Iraq war of 2003 and being located closer to the continent. Also, I was not very surprised about the bombings in Stockholm.
