Research direction
Start with sol_mgpressure3ddev.cu around line 388 and run MultigridTest through make test, using the attached unittest.txt and memcheck.txt as references. Trace why _num_level is overwritten and verify the unit tests pass without the reported memory errors under valgrind.
Written by the indexing model from the issue text.
Description
What steps will reproduce the problem?
1. build for sm_10 (using netcdf4 and a GeForce 8800 GTX)
2. make test
What is the expected output?
All tests should be ok.
What do you see instead?
see attached unittest.txt
What version of the product are you using? On what operating system?
1.0.0 on Ubuntu 8.04 LTS
Please provide any additional information below.
I ran utest MultigridTest under a debugger and found that at line 388 of
sol_mgpressure3ddev.cu the value of _num_level is not 6 as it should be
but a very large value. Something is obviously overwritten. I also ran
utest MultigridTest under valgrind and the output is in the attached file
memcheck.txt.
