Naming Conventions in Sparse BLAS Level 2 and Level 3

Each Sparse BLAS Level 2 and Level 3 routine has a six- or eight-character base name preceded by the prefix mkl_ or mkl_cspblas_ .

The routines with typical (conventional) interface have six-character base names in accordance with the template:

mkl_<character > <data> <operation>( )

The routines with simplified interfaces have eight-character base names in accordance with the templates:

mkl_<character > <data> <mtype> <operation>( )
for routines with one-based indexing; and
mkl_cspblas_<character> <data>  <mtype> <operation>( )
for routines with zero-based indexing.

The <character> field indicates the data type:

s

real, single precision

c

complex, single precision

d

real, double precision

z

complex, double precision

The <data> field indicates the sparse matrix storage format (see section Sparse Matrix Storage Formats):

coo

coordinate format

csr

compressed sparse row format and its variations

csc

compressed sparse column format and its variations

dia

diagonal format

sky

skyline storage format

bsr

block sparse row format and its variations

The <operation> field indicates the type of operation:

mv

matrix-vector product (Level 2)

mm

matrix-matrix product (Level 3)

sv

solving a single triangular system (Level 2)

sm

solving triangular systems with multiple right-hand sides (Level 3)

The field <mtype> indicates the matrix type:

ge

sparse representation of a general matrix

sy

sparse representation of the upper or lower triangle of a symmetric matrix

tr

sparse representation of a triangular matrix
