Detailed Description

Provides the ALP implementation of a subset of the de-facto SpBLAS standard for sparse linear algebra kernels.

On installation, the header file to include is </alp/install/dir/>include/transition/spblas.h.

The prefix of the SpBLAS primitives is configurable via the –spblas-prefix= option to the bootstrap.sh script. The default prefix is alp_cspblas_*.
