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. You can read about it and download it from my website here: https://sites.google.com/site/scalable68/scalable-parallel-c-conjugate-gradient-linear-system-solver-library Thank you, Amine Moulay Ramdane.
