Hello, <BR>
<BR>
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. <BR>
<BR>
Thisis my log from executing ./ex2 -vec_type cuda<BR>
<BR>

application called MPI_Abort(MPI_COMM_WORLD, 86) - process 0<BR>
<BR>
<BR>
I configured my pets with following command:<BR>
<BR>
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<BR>
<BR>
Everything went ok. Then I compiled the library with <BR>
<BR>
make PETSC_DIR=/home/kuba/External/petsc-3.1-p6 PETSC_ARCH=linux-gnu-c-debug all<BR>
<BR>
and after that tests<BR>
<BR>
make PETSC_DIR=/home/kuba/External/petsc-3.1-p6 PETSC_ARCH=linux-gnu-c-debug test<BR>
<BR>
Tests were performed successfully.<BR>
<BR>
I have cuda configured in LD_LIBRARY_PATH:<BR>
<BR>
ldconfig -p | grep cuda<BR>

and I have cuda directories in PATH:<BR>

<BR>
Could you please help me with that.<BR>
<BR>
My final destination is to run CG and BICGSTAB solvers and measure performance using sparse matrices.<BR>
<BR>
Thank you in advance for your help.<BR>
<BR>
Best regards,<BR>
