Hello..


About Extreme Scaling in CAE Applications..

I have just read the following about Ansys company:

https://en.wikipedia.org/wiki/Ansys


Notice that Ansys develops and markets finite element analysis software 
used to simulate engineering problems.

I think that i have thought about this, and i have "invented"
a Scalable Parallel C++ Conjugate Gradient Linear System Solver Library,
in fact it scales "very" well, my library contains a Scalable Parallel 
implementation of Conjugate Gradient Dense Linear System Solver library 
that is NUMA-aware and cache-aware, and it contains also a Scalable
Parallel implementation of Conjugate Gradient Sparse Linear
System Solver library that is cache-aware.

Sparse linear system solvers are ubiquitous in high performance 
computing (HPC) and often are the most computational intensive parts in 
scientific computing codes. A few of the many applications relying on 
sparse linear solvers include fusion energy simulation, space weather 
simulation, climate modeling, and environmental modeling, and finite 
element method, and large-scale reservoir simulations to enhance oil 
recovery by the oil and gas industry.

Conjugate Gradient is known to converge to the exact solution in n steps 
for a matrix of size n, and was historically first seen as a direct 
method because of this. However, after a while people figured out that 
it works really well if you just stop the iteration much earlier - often 
you will get a very good approximation after much fewer than n steps. In 
fact, we can analyze how fast Conjugate gradient converges. The end 
result is that Conjugate gradient is used as an iterative method for 
large linear systems today.

System Solver Library from here:

Read the following about Extreme Scaling in CAE Applications, this is 
why i have invented my Scalable Parallel C++ Conjugate Gradient Linear 
System Solver Library that scales very well:
