Replaceability

KML_SCASOLVER supports multiple processes and threads on multiple nodes, which can replace the multi-node and multi-process function of PETSc.

Table 1 describes the mapping between replaceable interfaces and corresponding interfaces of the PETSc (only optimized interfaces are provided).

**Table 1** Replacement mapping of PETSc
PETSc Interface	KML_SCASOLVER Interface
KSPCreate	KmlScaissCgInitStripesDI
KSPSetTolerances	KmlScaissCgSetDII
KSPSolve	KmlScaissCgSolveDI
KSPGetIterationNumber/ KSPGetResidualNorm	KmlScaissCgGetDII/ KmlScaissCgGetDID
KSPDestroy	KmlScaissCgCleanDI

The preceding interfaces are C interfaces. For details, see the section about KML_SCASOLVER function syntax in Kunpeng Math Library Developer Guide.
