Could you try checking out the latest version from hg and seeing if you can
reproduce?
Instructions here:
http://code.google.com/p/opencurrent/source/checkout
Also, are you on a 32-bit or 64-bit OS?

Dear Jonathan,
I downloaded your latest versions per your instructions and I got the
attached output from the unit tests. My system is 32-bit and has a
GeForce 8800 GTX which only has floats, no doubles. I use NetCdf 4.0.
Running utest MultigridTest in a debugger now revealed that the
segmentation fault was caused by 'this' in the code below having the
value 0xad0 which is obviously not a valid address of an object in
Linux.
Grid2DDevice<T>::~Grid2DDevice()
{
cudaFree(this->_buffer);
}
This destructor was called from delete _diag_grid[l]; (line 335
sol_mgpressure3ddev.cu).
Hope this helps!

Dear Jonathan,
Last week I got a new graphics card. I now have a GTX-285. This made things
even worse.
I recompiled for sm_13 and got the attached output for make test. This is the
version
I downloaded on March 19. I also tried the official version 1.0.0 again and
here too
things got worse. I attach both make test outputs.
I hope you can figure out what is wrong.
Sincerely, Anneke

hmm, it looks like this has nothing to do with the graphics card, and maybe
nothing
to do with cuda. Might be an issue with how netcdf was built?
My guess is a libc incompatibility or something like that.
Could you run 'ldd -v tests/utest' and attach the results?

Here are the results. btw, if I compile for netcdf 3, which is included in
Ubuntu
8.04, so not built by me, the problems are only slightly different, see the
other
attachment which was made with the recent opencurrent snapshot, not with 1.0.0.

are you able to compile and run the cuda sdk samples? or any cuda progam?

Yes I am able to compile and run all CUDA example programs plus Iterative CUDA
and
OpenNL with CUDA support.
I hope this message gets through now at last, I tried it over a few weeks
repeatedly. There seems to be some problem with me contacting this bulletin
board
system.
