LU Decomposition and associated documentation in MAGMA?

Postby Puyan Lotfi » Tue May 24, 2011 4:19 pm

Hi

I am looking for the LU Decomposition code for MAGMA. I found a file dgemv_MLU.cu in the latest code base, but I can't seem to find any documentation on it in the documentation section of the website.
Anyone have any tips?

Hi,

the LU decomposition is in the file src/[zcds]getrf.c

zgemv_MLU.c, as said by its name, is a variant of the GEneral Matrix-Vector mutiplication routines. You can find description of names by searching "blas refcard" in google/bing/... for BLAS functions and by looking at the LAPACK user guide for LAPACK functions.

In MAGMA, magmablas directory contains only BLAS function or auxiliary routines, and src directory contains all the LAPACK functions.
