#4278 — More precision about my Scalable Parallel C++ Conjugate Gradient Linear System Solver Library

Hello,

More precision about my Scalable Parallel C++ Conjugate Gradient Linear 
System Solver Library:

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. .

My Scalable Parallel C++ Conjugate Gradient Linear System Solver
Library for Windows and Linux was updated to version 1.70,
it was more optimized, and this version is much more stable
and scalable and very fast:

Author: Amine Moulay Ramdane

Description:

This 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.

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.
