Dear RegCM community,

        I'm a postergraduate student named Wenchao Wang in Nanjing university of Information Science & Technology (NUIST) while my major is Meteorology.

        When I use the latest version RegCM-5.0.0（Released），I find that the results are always biased everytime. However, I used the same driver data.

        Fig1 shows the state at the beginning of the run and fig2 shows the state of integration after a period of time.（The left image is the state of the first run, and the right image is the state of the second run.）

The only difference between the two is the number of CPU cores on the high-performance computer I used.Fig 3 is the root-mean-square error of my previous 5 calculations.

        Do different numbers of cores affect the results?
