[Pw_forum] discrepancy in tests

[yuanqing.wang at riken.jp]

Dear all, 

  I have checked the difference (please see below). In fact, the 
difference is  obvious. Now, I do not know where this problem comes 
from and how should I do to fix it. Can you give  me some advice?

Thanks in advance.

Best, 

Yuanqing Wang
