I am trying to compile h2opus for CPUs.
Unfortunately, the thrust
library is not available at the provided link https://github.com/thrust/thrust. Instead, it is now distributed by nvidia at https://github.com/NVIDIA/thrust.
Could you please pinpoint us to the release of thrust that is compatible with h2opus
?
Thank you,
Umberto
Hello,
Currently I would like to use H2Opus to accelerate my home made 3D electrostatic BEM solver (Boundary Element Method) which runs on the GPU. The N cells data used to build an NxN non symmetric dense matrix are stored in the GPU memory and the matrix elements are thus computed on the GPU. I would like to know if H2Opus has a method to construct a non symmetric HMatrix directly on the GPU.
Thanks a lot for any answer/clue and for this very promising library.
Hi,
Up to now I managed to compile H2Opus on a laptop running Ubuntu 22.04 LTS with Cuda 11.5 and with a Quadro RTX 5000 (16 GB). However, when trying to compile the examples, there are some missing functions or other bugs.
For eig:

Where could I get the missing functions which are not included in the repository files ?
Thanks a lot for any help,
