Bug #221
gmxtest.pl not reporting errors in check_force, check_virial, and check_xvg
Description
Line 200 in gmxtest.pl assigns the output of a shell command to $nerr_pot. This value has a newline appended to it, and even if the result is zero errors, perl will treat a "0\n" as a true value, and it will ignore $nerr_force, $nerr_vir, and $nerr_xvg when determining $nerror.
Adding a chomp($nerr_pot) fixes the problem, and also happens to reveal 7 failures in the single precision complex tests, all in check_virial. This is on 3.3.3 running on Linux x86_64.
History
#1 Updated by David van der Spoel over 11 years ago
I've added the chomp to the cvs version. However I do not get more errors than without it. Could it be that you use the gcc 4.1.x compiler?
#2 Updated by Allan Tong over 11 years ago
I've tried gcc 3.3, 3.4, 4.2, and 4.3. In all cases I get the failures running the tests with SSE. Compiling with "-O0" and running the C-loops, however, the tests all pass. So it seems that the failures I'm seeing are only with x86_64 SSE.

And what is the nature of the failures? Are the results very different?

gmxcheck output
This is checkvir.out from the field test. Overall the values don't seem to be that far off to me.
#5 Updated by David van der Spoel about 11 years ago
Indeed the values are quite similar. Since I added the chomp I'm closing this bugreport now.
