Hello,

Read this:


My Parallel C++ Conjugate Gradient Linear System Solver Library that
scales very well was updated to version 1.74

Here is what i have enhanced:

The Solve() method is now thread-safe, so you can call it from multiple
threads, everything else is thread-safe except for the constructor , you
have to call the constructor one time from a process and use the object
from multiple threads.

I think that my library is much more stable and fast and it works
on both Windows and Linux.

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.
