Hi, In an effort to make a Qt gui using MPI, I have the following:
1. Gui started in master node. 2. In Gui, through a pushbutton, a global variable x is assigned some value; let say, x=1000; 3. I want this value to be know to all nodes. So I used broadcast in the function assigning it on the master node and all other nodes. 4. I printed values of x, which prints all 1000 in all nodes. 5. Now control has reached to MPI_Finalize in all nodes except master. Now If I want to reassign value of x using pushbutton in master node and again broadcast to and print in all nodes, can it be done?? I mean, can I have an MPI function which through GUI is called many times and assigns and prints WHILE program is running. OR simply can I have a print function which is printing noderank value in all nodes whenever pushbutton is pressed while program is running. command i used is "mpirun -np 3 ./a.out". Any help will be appreciated. Thanks you very much. -- eye51
