amgX error


I m running amgx with fgmres to solve a problem , but when i try to run the code i get the following error

Caught amgx exception: Unsupported block size for strong connections
at: /home-2/marsaev/beta_test/release_1.2/amg/core/src/classical/strength/

for a different and small input the code runs just fine…but when i get a bigger input it stops at


Can anyone help me?

P.s. i am new to all this :)

Maybe you could paste the whole code implementation? Did you try the .c codes in the examples folders and use your system as input in .mtx format?

I found that my .json file was wrong and didn t run the algorithm with the proper input parameters
