Source for scalability challenge for number of finite element nodes per process
Context
In distributed simulation of a finite element mesh with $N$ nodes and $P$ processes, a professor stated to me that "achieving good scaling for more than 25,000 finite element nodes per ...

Non-dimensionalizing the Ideal MHD System
Non-dimensionalization is a really frustrating topic for me, and I imagine many others, because in school it was glossed over while being really important to implementing a simulation.
I'm writing a ...

What is the name of the theory that combines 3d discretized surfaces and distributed numerical algebra
I've looked into distributed numerical computation work before, but I've realized that 3D applications are all about 3d surfaces and meshes.So I'd like to look into related work on mesh and parallel ...

row and column based distributed LU factorization
The LU parallel computation theories I've seen are based on $M\times N$ mesh computations, is there a theory for one dimensional device mesh LU parallel decomposition?
For example, $A$ is a matrix. we ...
