SBLAS (Legacy Interface)

Introduction

Remarks
This page is intended for users who will use API version 1 of SBLAS. Fortran interfaces has been changed between the API version 1 and 2.0. It is recommended to use the library with the API version 2.0 or later.

The SBLAS (Sparse BLAS) are an extension to the Level 1 BLAS subprograms, targeted at sparse vector operations.

They are from ACM Algorithm 692 [1].

How to use SBLAS

• The SBLAS Routine List contains one-line summaries for SBLAS subprograms.
• Compiling and Linking tells how to compile and link with the SBLAS library.

SBLAS Routine List

^† ? indicates prefix which must be filled with a combination of:
S = REAL(kind=4), D = REAL(kind=8), C = COMPLEX(kind=4), Z = COMPLEX(kind=8)

Name†	Prefixes	Description
?DOTI SDOTI DDOTI	S D	Dot product, real
?DOTUI CDOTUI ZDOTUI	C Z	Dot product, complex
?DOTCI CDOTCI ZDOTCI	C Z	Dot product, complex conjugate first vector
?AXPYI SAXPYI DAXPYI CAXPYI ZAXPYI	S D C Z	Vector scale and add
?ROTI SROTI DROTI	S D	Apply Givens rotation
?GTHR SGTHR DGTHR CGTHR ZGTHR	S D C Z	Gather vector y into vector x
?GTHRZ SGTHRZ DGTHRZ CGTHRZ ZGTHRZ	S D C Z	Gather vector y into vector x, and zero vector y
?SCTR SSCTR DSCTR CSCTR ZSCTR	S D C Z	Scatter vector x into vector y
