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

auto-migrated Priority-Medium Type-Defect
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.
