GETRF: Integrate IPIV array in the interface and testings
-
Fix some issues in the actual getrf testing:
- seed incorrectly initialized
- Diagonal not dominant by default => Since LU NoPiv, diagonal dominant is the default for the generation.
- Integrate the swap locally on the home node 0 if needed.
-
Add the IPIV to all getrf interfaces
