Re: [petsc-users] Tweaking my code for CUDA

Ok so, i went back and erased the old libpetsc.so.3 i think it was the one causing problems, i had --with-shared-libraries=0 and the installation complained of not having that file, then reinstalled with --with-shared-libraries=1 and it is finally recognizing my system installation with only CUDA,

Re: [petsc-users] Tweaking my code for CUDA

Ok well, it turns out the $PETSC_DIR points to the testpetsc directory, and it makes, install and tests without problems (only a problem on ex5f) but trying to reconfigure on valera/petsc directory asks me to change the $PETSC_DIR variable, Meanwhile the system installation still points to the

Re: [petsc-users] Tweaking my code for CUDA

Yes, this is the system installation that is being correctly linked (the linear solver and model are not linking the correct installation idk why yet) i configured with only CUDA this time because of the message Karl Rupp posted on my installation thread, where he says only one type of library

Ok lets try that, if i go to /home/valera/testpetsc/arch-linux2-c-opt/tests/src/snes/examples/tutorials there is runex19.sh and a lot of other ex19 variantes, but if i run that i get: [valera@node50 tutorials]$ ./runex19.sh not ok snes_tutorials-ex19_1 #

Ok thanks Matt, i made a smaller case with only the linear solver and a 25x25 matrix, the error i have in this case is: [valera@node50 alone]$ mpirun -n 1 ./linsolve -vec_type cusp -mat_type aijcusparse laplacian.petsc ! TrivSoln loaded, size: 125 / 125 RHS loaded, size:

[petsc-users] Tweaking my code for CUDA

Hello all, I am working on porting a linear solver into GPUs for timing purposes, so far i've been able to compile and run the CUSP libraries and compile PETSc to be used with CUSP and ViennaCL, after the initial runs i noticed some errors, they are different for different flags and i would
