PBP values in test sample-out require OLD_GAUSSRAN #47

Open jxy opened 2 years ago

The PBP values in

grep PBP ks_spectrum/test/ks_spectrum_hisq.spectrum2.2.sample-out 
PBP: mass 3.000000e-02     2.449311e-02  3.028505e-02  -5.751583e-03  -5.751606e-03 ( 1 of 1 )
PBP: mass 5.000000e-02     3.837426e-02  5.139182e-02  -4.210568e-03  -4.210593e-03 ( 1 of 1 )

require -DOLD_GAUSSRAN to reproduce. The new default RNG results should be

grep PBP ks_spectrum_hisq.spectrum2.2.out 
PBP: mass 3.000000e-02     2.745315e-02  2.581980e-02  3.717043e-03  3.717122e-03 ( 1 of 1 )
PBP: mass 5.000000e-02     3.578432e-02  5.238890e-02  -9.484699e-04  -9.484301e-04 ( 1 of 1 )

I didn't go through all the tests.

Hi Xiao-Yong,

Thank you for pointing out this obsolescence.   I hope it didn't cause you a lot of trouble.  I will fix it in the next update of the develop version.

Best,

Carleton
