[petsc-users] The "DMComplexDistribute" is time-consuming

[fdkong]

Hi developers,


I use DMComplex represent the unstructured mesh. Everything is OK, but the function "DMComplexDistribute" is always time-consuming. I guess that it results from using the PetscSF. I don't know why we use this communication model. Could you please make some tests on the function?  Or could we use other communication functions ?
