installation issue about v3.0.0

[ZhouChao2018]

Hello acharara,
The following error occurred when I built the KBLAS.It seems to be a cast error.
batch_triangular/Xtrmm_batch.cu(83): error: argument of type "float **" is incompatible with parameter of type "magma_int_t"

batch_triangular/Xtrmm_batch.cu(84): error: argument of type "int" is incompatible with parameter of type "float **"
Do you have any ideas?

Hello ZhouChao,
Apparently, the signature if a routine in MAGMA API has been modified with latest MAGMA releases. You can avoid this error for now by switching MAGMA off in the make.inc file of KBLAS (comment out USE_MAGMA around line 30).
Otherwise, I will fix this and commit it soon.

Thanks for your report

Hello,

On Ubuntu 22.04 running CUDA 11.7, I am trying to install H2Opus which requires installation of KBLAS-GPU. I have successfully installed MAGMA (from bitbucket: https://bitbucket.org/icl/magma/get/3816143865f0.zip, version 2.7.0?).
However, when trying to compile KBLAS-GPU with the attached make.inc, I get lots of errors of the type :
batch_triangular/Xgemm_batch_core.cuh(437): error: argument of type "magma_int_t *" is incompatible with parameter of type "magma_int_t"
detected during instantiation of "int Xgemm_batch_nonuniform_core(kblasHandle_t, char, char, int *, int *, int *, T, const T **, int, int, int *, const T **, int, int, int *, T, T **, int, int, int *, int, int, int, int) [with T=float]"
......

batch_triangular/Xtrsm_batch_drivers.cuh(326): error: argument of type "int *" is incompatible with parameter of type "magma_int_t"
detected during instantiation of "int Xtrsm_batch_nonuniform_core(kblasHandle_t, char, char, char, char, int *, int *, T, T **, int *, T **, int *, int, int, int) [with T=double]"
batch_triangular/Xtrsm_batch.cu(130): here
make.txt

Could you please indicate which version of magma should be used ? Or better, could you upload a KLAS-GPU version compatible with the latest MAGMA version ?

Thanks a lot for any help,

Gilles

Hi Gilles,

I tried with magma 2.6.0 to build kblas-gpu and it works.
To get magma 2.6.0, use
wget http://icl.utk.edu/projectsfiles/magma/downloads/magma-2.6.0.tar.gz
magma 2.6.2 will fail.
We will look into adapting latest magma.

Best,
Yuxi

Hi Yuxi, Thanks a lot for your answer, I could compile KBLAS-GPU, using MAGMA version 2.6.0. However when trying to compile H2OPUS it indicates that the file kblas_potrf.h is missing and indeed, when checking on git hub or in my KBLAS-GPU folder, it is not present. Is there another repository to download KBALS-GPU from ? Best regards, Gilles

Hi Gilles,

1. H2OPUS expose a marco H2OPUS_USE_MAGMA_POTRF to switch potrf backend.
   in make.inc, add H2OPUS_USE_MAGMA_POTRF=1 then H2OPUS will use magma potrf.
   kblas potrf is still in dev, hope we will soon release and you can test perf of it.

2. Also, to compile H2OPUS shared library, you need to add

COPTS += -fPIC
NVOPTS += -Xcompiler -fPIC

to kblas make.inc.

So please first apply (2) and recompile kblas. Then apply (1) and compile h2opus.

Then you are good to go!

Best,
Yuxi
