Re: [Libmesh-users] API for job memory requirements

2017-03-24 Thread Cody Permann
We've looked at this several times and it's very difficult to estimate memory growth for complex C++ software. Each data structure that's spread throughout the code uses their own memory allocator to store information as needed. Even if you know things like the sizes of individual nodes in a node b

[Libmesh-users] API for job memory requirements

2017-03-23 Thread Fabio Canesin
Dear experts, Is there a api for computing the memory requirements of a FEMSystem or EquationSystem ? In running a navier-stokes 1MM mesh I constantly hit memory errors, even with ParallelMesh. My intent is to compute how much memory I need in each node for each number of mpi tasks before submitt
