mailing-list etiquette. I'm new to the mailing list and to QE.<br>
I've been running through the examples in PW and XSpectra. In the<br>
PW/examples folder, the following examples result in sets of warnings<br>
like these:<br>
Note: The following floating-point exceptions are signalling:<br>
IEEE_UNDERFLOW_FLAG IEEE_DENORMAL<br>
Note: The following floating-point exceptions are signalling:<br>
IEEE_UNDERFLOW_FLAG IEEE_DENORMAL<br>
Note: The following floating-point exceptions are signalling:<br>
IEEE_UNDERFLOW_FLAG IEEE_DENORMAL<br>
Note: The following floating-point exceptions are signalling:<br>
IEEE_UNDERFLOW_FLAG IEEE_DENORMAL<br>
<br>
All of the tests in run_tests executed with success.<br>
<br>
I don't know how to compare the outputs with those in the reference<br>
directories, but they all seem to be populated with numbers instead of<br>
NaN. The examples in PW displaying this behavior are<br>
example01, example04, example06, example07, example09,<br>
example11,example12, ESM_example, EXX_example, gatefield and<br>
vdwDF_example. The others ran to completion with no complaint.<br>
<br>
In XSpectra, of the four examples, the two that die this way are<br>
run_example_Cu_L23 and run_example_SiO2_USPP. The latter produces<br>
.dat files which look like those in the reference folder except for a<br>
4eV shift, even though they displayed the underflow warning. The<br>
former example dies at the point indicated in the attached shell file.<br>
While it produces an output XANES spectrum (xanes.dat), that spectrum<br>
doesn't look like any of the .dat files in the reference folder.<br>
The Cu.wfc file looks like a concatenation of wavefunctions for<br>
1s,2s,2p, 3s and 3p, as I think it should.<br>
