[Pw_forum] testing the PW execution

[Stephen Chan]

Hello,

I am trying to install QE on my local PC. As I'm new to this area, I tried
the simplest way to compile:
./configure
make pw

Apparently the compilation went fine, but when I tried:
cd PW/tests
./check-pw.x.j

For each test, I got this warning:
Note: The following floating-point exceptions are signalling: IEEE_DENORMAL

Discrepancies from the reference figures were also reported:
discrepancy in total energy detected
Reference:   -44.618060, You got:   -44.618132
discrepancy in force detected
Reference:   0.0030, You got:   0.0033
discrepancy in pressure detected
Reference: 189.41, You got: 189.56

Please let me know if you need further info from my side. I'd be happy if
you could give me some directions in resolving the problem.

Kind regards,
Stephen
