Re: [gembud] > 2GB files

Adding -xarch=generic64 in Makeinc.x86 should work. I will try that in the AM.

Well duh it just occurred to me. Solaris will support 32 bit and 64 bit apps, 
unlike Windows and I think Linux..so maybe the answer lies there..

So on 64-bit Linux you just do a make all/make install and it reads files > 
2GB?  Wow that's an ancient SPARC machine if it was 32-bit since Solaris became 
64-bit in 2000. I have been building GEMPAK on 64-bit Solaris x86/x64 platforms 
for many years and none have read files bigger than 2GB even though it will 
decode the files. That's using Oracle/Sun compilers. Maybe it is a Solaris 
Studio versus gcc/f77 thing...

?Hi Robert,


Good question ... there definitely doesn't seem to be an issue loading a > 2GB 
grid on a 64-bit Linux system.  32-bit linux does not work.  I tried on a 64 
bit Sparc as well and that did not work, but I suspect the version of GEMPAK 
was built on a 32-bit platform.  I'll try building a 64-bit executable on the 
Sparc box as time permits.

Kevin,

Solaris has been 64-bit for years and I can't read GFS 0.5 filed that are 
larger than 2GB. Is there something in the config prior to compile process that 
allows GEMPAK to read 2GB+ files?

Thanks,

Hmm, I'll rig up a similar pqact and see what I see on my end.

I don't think GEMPAK should have any problem reading a 2GB grid, as long as you 
are using a 64-bit version of the software on a 64-bit OS.  We can read from 
HRRR GEMPAK files that are typically of size 2.2-2.5 GB without any problem ...

The "can not decode" errors are just from GRIB2 fields that don't have a match 
in the grib tables in $GEMTBL/grid ... with a little research those ought to be 
able to be resolved.

I am not sure if I am supposed to reply to all, but it appears to be a decoding 
problem, although I am not sure what is causing it.

The file is piped through the LDM via this action, which should work.
NGRID|CONDUIT   (^[LM].B... KWBE|prod/nam.*awip12)
        PIPE    /opt/gempak/GEMPAK7/os/linux64/bin/dcgrib2 -d 
/atmo/data/gempak/logs/dcgrib2_NAM218.log
                -e GEMTBL=/opt/gempak/GEMPAK7/gempak/tables

We're also starting to store data in grib2 format data as well.  I figured I 
could just write another action.
CONDUIT prod/nam\.(........)/nam\.t(..)z\.awip12(..)
        FILE    -log /atmo/data/gempak/model/nam12km/grib2/\1\2_fh_\3.grib2

which appears to be working.


Here is small part of my log for the decoding into gem format.

Hi Charles,

My guess is that the GEMPAK grid did not get created properly.  Its header 
might be correct, which is why gdinfo shows it, but it may not have any 
meaningful information in it so none of the plotting programs work.

What version of GEMPAK are you running? Did you create the GEMPAK grid file 
yourself (i.e. using dcgrib2 or nagrib2 from the GRIB2 file) or is it 
automatically received in your department?

If you have IDV, try pointing it to that grid file and see if it can display 
anything.

Subject: [gembud] gdlist gdplot2 problems

Hello,

I am trying to plot some basic grids with gdplot2, although I have run into 
some trouble.

I first used gdinfo to see if the grid existed and I believe it does in my 
attached terminal output.
However,  when I run gdlist on the same exact arguments,  I receive this error

 [DG -7]  Input grid TMPK ^140430/1800F084 @500 %PRES cannot be found.

which doesn't make any sense because GDINFO shows the grid in this file.
Does anyone have any idea what I am doing wrong?

I receive the same error in gdplot2.

Thanks,
Charles
