Hi Simon / all,

I am back to work. I made the necessary corrections as suggested in the two previous mails. I changed the unit number to 205 in param.F and ICBC.f. Also in regcm.x I linked the icbc file to fort.205. regcm.x runs and stops after a while showing something linking problem with fort.103 whereas I can't find it where it has been linked. I am attaching the regcm.out file. Can you/someone find out the solution for this.

Regards

Shekhar

Dear Mark,Simon and others,

I changed the Main/Makefile file according to Mark, that is,

---------------------------------------------------------
FFLAGS = -64 -O3 -static -TENV:check_div=3:X=0 \
-TARG:exec_min=UOZV:exec_max=UOZV -OPT:fast_nint=OFF:Olimit=4657 -IPA \
-LANG:short_circuit_conditionals=ON:recursive=ON
-----------------------------------------------------------

and the RegCM3 running now~!
Although it still had some warning message, like:
----------------------------------------------------------
Warning: Option 'exec_min' not in group 'TARG' (TARG:exec_min=UOZV)
Warning: Option 'exec_max' not in group 'TARG' (TARG:exec_max=UOZV)
-----------------------------------------------------------
I think this might be caused by the version of my SGI (IRIX64 icce6899 6.5 6.5.16m 04101931 IP35) is earlier thant Mark's.
But finally, it worked!
Thanks a lot~! ^__^



Additionally, as Mark concluded,
here I'd like to share what I changed duiring my running RegCM3 on SGI platform.:)

1) change "ibyte=4" in PreProc/Terrain/domain.param
Actually, when I used f77 in running previous versions of RegCM3, the ibyte is 1.

This also confused me why f90 need ibyte=4 while f77 is ibyte=1.

2) I changed the iutbc in param.F to 201, so my ICBC file is fort.201,fort.202, and so on.

3) Adjust the right path of 'cpp' in Main/MAKECODE file.

4) Finally, I've just adjusted the Main/Makefile as Mark has mentioned. Thanks again!

And Other Makefiles I'm using is including in the latest RegCM3 (June 13th).




Best Regards,

Jing
