Thank you.
I tried to increase the numpar from 7500 to 30000. And the differences are much smaller:

The sequential version:
The MPI version:
So, I think that this differences now acceptable right?

Thank you.

Thank you！ I Checked the source code and saw how it is using MPI to parallelize the particle loop. And I used -DMPI flag to compile the "hycm_std" to run the same example as "hycs_std". However I found the result PostScript produced by "hycm_std" was not the same as the one produced by "hycs_std". I...

Hi, everyone. I'm looking through the code of concentration program. I notice that there are two ways to generate the random number for particle dispersion: 1. If Krand=1, will use the pre-calculated random number array. 2. If Krand=2, will use the "parvar" subroutine inside the dispersion subroutin...

Thanks a lot for help.
One more question, are all the HYSPLT application in ./trunk folder? I'm not very familiar with SVN project structure, so just to make sure this.

Also,here is the 012 result.

By the way, because I'm new to SVN revision control, is the whole hysplit program in the ./trunk folder?
Thank you.

Follow up.
But a few results, for example 510, are very different and even not appear on the sample result pdf.

Thanks for replying.
Here are the 010 result from two versions of ./xrun.scr. (the whole results are too big to upload as attachment).
One is using Intel FORTRAN compiler 17.0, the other one is using pgfortran 16.10c.
Most result are like this one, with very little different.

Hi, I downloaded the code from SVN server, and compiled it using intel fortran compiler (change the FC in makefile to ifort). The version I use is 896. When compiling, everything seems to be okay and there was no error. After running compile.sh, I run ./testing/xrun.scr and produced results.ps in /t...
