Distributed multigrid linear solver library on GPU
I wanted to know whether it is possible to run several solves in parallel, if they will all fit in GPU memory. The use case is as follows - there...
Good day. I am trying to apply the distributed matrix loading approach from the example AMGX / examples / amgx_mpi_capi_cla.c in my code. The peculiarity of my code is that...
Hi, Can you help explain how to use the profile build type? I do see some tic toc functions in the code. But did not find where those data output...
Hello, I am not sure about the underlying multi GPU concept of amgX. The application I have in mind has the following features: - distributed memory CFD domain decomposition using...
Hi, Please let me know if anyone has successfully integrated AmgX library with OpenFOAM. Regards, Irfan
Now I am trying to work with your library and I have a problem. I solve the diffusion equation by the implicit Galerkin method. I want to get a solution...
When I use amgx_capi to solve some sparse linear system, it comes out that most of the default configs cannot be loaded into the API. Some default config will be...
Is CC 3.0 really not compatible? We have tested and everything seems to be fine on 660ti. Nonetheless, there are many occurrences of hardcoded requirement of CC>=3.5. Is it safe...
If `monitor_residual` is not set or set to 0 in the config, then `AMGX_solver_get_status()` silently returns 0 (success) regardless of convergence. Perhaps this should be made explicit in the reference...
There are two errors in the 5 point 2D discretization of Poisson's equation. The A matrix is generated in the example code that comes along with AmgX library as follows:...
