Hi, I have a problem where I want to grow the size of a Vec (or Mat) many times during program execution. I think for efficiency purposes I would just want to allocate a maximum size, and then only use the portion that I need. In the vector case, it is rather simple, just use the beginning of the vector, and add values to the end.
This leads to me to the problem of processor ownership ranges. From a previous email I noticed one could use the PetscLayout object and keep adjusting it as the useful part of the vector grows. Does this sound like a good approach? I noticed the PetscLayout is not available in Fortran bindings. Any workarounds for this? I suppose I can just manually calculate the processor ranges? Thanks for the help, Wes -------------- next part -------------- An HTML attachment was scrubbed...
