Migration from Netlib SCALAPACK to KML_SCALAPACK

Replaceability

The Fortran interfaces of SCALAPACK are the same as those of Netlib SCALAPACK.

Table 1 describes the mapping between replaceable SCALAPACK interfaces and Fortran interfaces in Netlib SCALAPACK. Only optimized interfaces are provided.

The preceding interfaces are Fortran interfaces. When using these interfaces in the C language, you need to add an underscore (_) after the interface name. The parameter type is a pointer. For details, see "Kunpeng Math Library Developer Guide" > "Applied Math Libraries" > "KML_SCALAPACK Library Functions" > "Function Syntax" in Kunpeng HPCKit 26.1.RC1 Developer Guide.

Migrating the C-based Library

The Fortran interfaces provided by KML_SCALAPACK are the same as those provided by Netlib SCALAPACK. When the C language is used, you can use #include "kscalapack.h" to obtain the interface declaration.

Other code does not need to be modified.

Migrating the Fortran-based Library

The Fortran interfaces are the same as those of Netlib SCALAPACK. The code does not need to be modified.
