MPI rebuild example

Open neoshihchaokao opened this issue 2 years ago • 5 comments

I am trying to use the MPI rebuild technique which is provided in ver 1.4.3, but I did not find the suitable example I can refer. Does someone can provide a suitable example I can refer? Thanks a lot

Dear Denis, Thanks for your reply. However, I still encounter the runtime issue and need your help. Since I need to solve the linear system with a lot of RHS vectors and the shared_ptr given below is used to perform the setup phase once in AMGCL 789 123

According to the example you provide, I modify my code as follows: 456

However, the above MPI rebuild function always fails. Is there any idea to fix it ?
