Where is the sparse blas ?

In 1.5.0-beta3, I found *ailu_chow_csr_*.cu in magma-1.5.0-beta3/sparse-iter/blas directory.
But i can't find it in 1.5.0 version.
Is the name changed?

And Where could I find some information to sparse solver in detail ?
Thanks a lot!

I think this particular routine is still in development and not yet released. (Being in beta 3 was an oversight.)

Documentation is available online.
http://icl.cs.utk.edu/projectsfiles/mag ... lvers.html

Examples are given in sparse-iter/testing. I expect more detailed information will come out as we continue to develop the MAGMA sparse functionality. If you have questions about how to use specific routines, please ask here on the forum.

Thank mark, first.
I also have a little problem in my a piece of code.
I met a segmentation fault in magma_d_vtransfer
after magma_d_vread
magma_int_t length=300;
char rhs_name[]="utm300_b.mtx";

I have no idea why it happened.
Do I use MAGMA in the wrong way?
Thank you again.

sean791121,

there is indeed a bug in the d_vread(). I found it, and in the next release (November) this issue should be resolved.
