Does MAGMA1.0 & Above support Geforce 9series?

Does MAGMA 1.0 support Geforce 9 Series?

Thanks.

See http://developer.nvidia.com/cuda-gpus for a list of CUDA-enabled GPUs. MAGMA supports both CUDA 1.x and CUDA 2.x (Fermi) GPUs. Set the appropriate CUDA version in the make.inc file (GPU_TARGET=0 for CUDA 1.x, GPU_TARGET=1 for CUDA 2.x). However, only GPUs with CUDA 1.3 and above support double precision.

Thanks Mark!

I am trying to install MAGMA 1.0 under ubuntu 10.10.
When compilation, I encountered such problem,

Code: Select all

/home/ian/magma_1.0.0/control'
gfortran -O3 -DADD_ -x f95-cpp-input -Dmagma_devptr_t="integer(kind=../control/sizeptr.c: In function ‘main’: ../control/sizeptr.c:6:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘unsigned int’ 4)" -I/usr/local/cuda/include -I../include -I../quark/include -c magma_zfortran.f90 -o magma_zfortran.o

Here is my configuration (atlas installed through binary package):

I have been lurking around the forum all day trying to find a solution. I don't know too much about compiler setting, so I am also reading literature about what the meaning of the flags. But I still feel kinda lost.
Thanks in advance for any input!

Notice the Fortran compile command is gibberish:

gfortran -O3 -DADD_ -x f95-cpp-input -Dmagma_devptr_t="integer(kind=../control/sizeptr.c: In function ‘main’: ../control/sizeptr.c:6:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘unsigned int’ 4)" ...

It should look like:

gfortran -O3 -DADD_ -x f95-cpp-input -Dmagma_devptr_t="integer(kind=4)" ...

What's happening is that it is compiling & running sizeptr to get the size of a pointer in C, and using the output of that in the Fortran compile command. The output should be just "4" or "8", but in this case there is a warning when compiling sizeptr, which is erroneously getting stuck into the Fortran compile line. The fix is simple: Replace control/sizeptr.c with the attached version, which should compile without errors.

Thanks for interpretation of problem. I learn a lot from it. The patch you wrote is straightforward and effective. I encountered several similar errors mentioned in post below.

Now all have been fixed. It compiles.
Thank you, Mark.
