[petsc-users] pets-3.1-p6 with CUDA: Unknown vector type: cuda!

[Jakub Pola]

Hello, 

I was trying to use pets library with my GPU (GTX 460 ) and see how it
works. Unfortunatelly I cant run any example with -vec_type cuda. 

Thisis my log from executing ./ex2 -vec_type cuda

I configured my pets with following command:

petsc-3.1-p6$ ./config/configure.py --with-cc=gcc --with-fc=gfortran
--download-f-blas-lapack=1 --download-mpich=1 --with-cuda=1
--with-debug=no

Everything went ok. Then I compiled the library with 

make PETSC_DIR=/home/kuba/External/petsc-3.1-p6
PETSC_ARCH=linux-gnu-c-debug all

and after that tests

make PETSC_DIR=/home/kuba/External/petsc-3.1-p6
PETSC_ARCH=linux-gnu-c-debug test

Tests were performed successfully.

I have cuda configured in LD_LIBRARY_PATH:

ldconfig -p | grep cuda
	libicudata.so.42 (ELF) => /usr/lib/libicudata.so.42
	libcusparse.so.3 (libc6) => /usr/local/cuda/lib/libcusparse.so.3
	libcusparse.so (libc6) => /usr/local/cuda/lib/libcusparse.so
	libcurand.so.3 (libc6) => /usr/local/cuda/lib/libcurand.so.3
	libcurand.so (libc6) => /usr/local/cuda/lib/libcurand.so
	libcufft.so.3 (libc6) => /usr/local/cuda/lib/libcufft.so.3
	libcufft.so (libc6) => /usr/local/cuda/lib/libcufft.so

	libcuda.so.1 (libc6) => /usr/lib/nvidia-current/libcuda.so.1
	libcuda.so (libc6) => /usr/lib/nvidia-current/libcuda.so
	libcublas.so.3 (libc6) => /usr/local/cuda/lib/libcublas.so.3
	libcublas.so (libc6) => /usr/local/cuda/lib/libcublas.so

and I have cuda directories in PATH:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/kuba/bin:/usr/local/cuda/bin:/usr/local/cuda/include:/usr/local/cuda/lib:/usr/local/cuda/lib64"

Could you please help me with that.

My final destination is to run CG and BICGSTAB solvers and measure
performance using sparse matrices.

Thank you in advance for your help.

Best regards,
Jakub.
