Re: Multiprocessor run for linux hysplit dispersion

Hi, I found that it was not faster when using 15 MPI compared with single one processor. But there is no error message either.
Would it be possible for you that providing a detailed compiling instruction for multiprocessor use please?
Thanks so much for help!

Re: Multiprocessor run for linux hysplit dispersion

I manually add hycm_std in the exec/Makefile and recompile it. It generated hycm_std this time. It seems to be working well when I rerun the MPI using: $./../exec/run_mpi.sh 15 hycm_std But it is still very slow (need about 3 hours to run a 120 hours dispersion). However, I use a EMITIMES file inclu...

Multiprocessor run for linux hysplit dispersion

Hi there, I am trying to use multiprocessor to run the hysplit dispersion model on linux. I am not sure if I am using it in a right way. When I execute the hycs_std, I use the command of: $./../exec/run_mpi.sh 15 hycs_std (trying to use 15 mpi) But the calculation speed turns out the same with using...

Any limit on maximum records in EMITIMES file?

Hi everyone, I am using the dispersion model for a gas. 522 emission sources were included in my EMITIMES file. I am wondering if there is any limit on the max number of emission sources and the emission duration time as well? Here is the beginning of my EMITIMES file: YYYY MM DD HH DURATION(hhhh) #...
