[petsc-users] Performance of Conda Binary vs Self Compiled Version

[Jorge Nin]

Hi,
I was playing around with a self compiled version and, and a the Conda binary of Petsc on the same problem, on my M1 Mac.
Interestingly I found that the Conda binary solves the problem 2-3 times slower vs the self compiled version. (For context I’m using the petsc4py python interface) 

I’ve attached two log views to show the comparison.

I was mostly curious about the possible cause for this.
 I was also curious how I could use my own compiled version of PETSc in my Conda install? 


Best,
Jorge
