clMagma

[_Mike_]

Hello all,

I'm new with MAGMA and I would like to test the OpenCL version due to its multiplatform nature. But I'm having some troubles during compilation, therefore I would like to answer if someone have been able to install clmagma-1.0.0 under similar conditions:
- Ubuntu 12.04
- Processor: Intel i7
- Graphic card: Nvidia 210
- BLAS, LAPACK, ATLAS from the ubuntu repositories.

Regarding the corresponding make.inc configuration file is detailed below:

Code: Select all

CC        = g++
NVCC      = nvcc
FORT      = gfortran

ARCH      = ar
ARCHFLAGS = cr
RANLIB    = ranlib

OPTS      = -O0 -DADD_ -g -Wall
FOPTS     = -O0 -DADD_ -g -Wall -x f95-cpp-input
NVOPTS    = -O3 -DADD_ --compiler-options -fno-strict-aliasing -DUNIX
LDOPTS    = -fPIC -Xlinker -zmuldefs

LIB       = /usr/lib/lapack/liblapack.a \
            -llapack_atlas -lcblas -latlas -lf77blas -lm -lf2c -latlas -lOpenCL -lgfortran -lstdc++ -fopenmp -ldl -lgsl

GPUBLAS   = /usr/local/cuda


LIBDIR    = -L/usr/lib/atlas-base \
            -L$(GPUBLAS)/lib64
INC       = -I$(GPUBLAS)/include


I'd appreciate any help, thanks.

Since your GPU is Nvidia, you will probably want to use the CUDA MAGMA version, which is significantly more developed than the clMAGMA version. But if you really want to use clMAGMA, you need to use AMD's clAmdBLAS library (for OpenCL), not Nvidia's CUBLAS library (for CUDA).

Yes, that's my case

you need to use AMD's clAmdBLAS library (for OpenCL), not Nvidia's CUBLAS library (for CUDA).

Ok, so that's what I'm doing wrong... thx you very much for your help :)

Here is my topic where i posted my make.inc and Makefile.internal files, which i use to compile the library on my environment. As you can see from the thread, my system is similar to yours and i have a complete and running clMAGMA setup on NVIDIA card, but having some troubles as stated in that post (probably, due to some compatibility issues between clAmdBlas and NVIDIA card).

If you need more help on compiling, post here or contact me in pm!
Cheers
