Compiling ncep.noaa.gov grib2 code

Accelerated Computing HPC Compilers Legacy PGI Compilers

I am trying to compile these programs with pgroup compilers:

http://www.nco.ncep.noaa.gov/pmb/codes/GRIB2/

First of all, the pgf90 4.0-2 I have licensed does not understand all constructs used in g2lib code, so I tried 5.2 compilers with the evaluation license. This compiles but segfaults when I try to run it.

This looks like some bug in passing arguments to a subroutine.

I cannot be sure that there are no bugs in NCEP code there, but it seems to work for other people with other compilers. As I am currently using pgroup compilers, I thought to first try these.

Hi Jaakko,


Often times when a seg fault occurs at a call it’s caused by a stack overflow. Try setting your stack to unlimited, in csh the command is ‘unlimit’, and re-running.

I was able to build the libraries and the cnvgrib tool, but without data was unable to recreate the issue. If setting the stack size to unlimited doesn’t work, let me know and I’ll contact you via email about getting a sample data set.

Thanks,
Mat

Mat,

Thanks for the reply, great support. Unlimited stack did not help with pgf90 5.2. Tried on 64bit Opteron and 32bit Athlon. Here is a test case, this is a short GRIB2 file, public data from NCEP so I can post it here:

http://www.iki.fi/hyvatti/ncep.grib2

And this is the command line you may want to try:

./cnvgrib -g21 ncep.grib2 output.file

I have now succesfully compiled the utility with pgf90 4.0. I had to modify a lot of fortran constructs that did not compile with that vetsion. I also tested that 5.2 version compiler does not produce working code with these modifications that make 4.0 version accept the code.

4

After some debugging and a lot of discussion, we determined that the problem here is that the program has a subtle error that’s causing the seg fault. The gdt2gds subroutine’s actual argument gfld%list_opt is a nullified pointer. The intent being that it contains an empty option list. In the F95 standard however, in the case where the actual argument is a pointer and the dummy argument is not, then the dummy argument gets associated with the actual argument’s target. The pointer must have an associated target. (Reference Fortran 90/95 section 5.7.1) But when the program tries to copy in gfld%list_opt’s target, it seg faults since there is no associated target.

The simple fix is to either allocate gfld%list_opt, or use “-Minline” since the call to gdt2gds is eliminated.

Can the compiler help detect this error? While the compiler cannot detect this at compile time, compiling with the flag “-Mchkptr” will detect the error at runtime.

Can the compiler work around this error? Our compiler engineers determined that, while more complex than it might seem, we should be able to do this for a future release.

Thanks a lot!

Hello,

I’m trying to use cnvgrib too and I’ve got too a segmentation fault during the conversion…

I use Fedora Core 5 on a Dual Core AMD Opteron™ Processor 285 machine.

No error during the compilation…

I tried to edit the makefile and to add :

FC =            pgf90 -Mbounds

or

FC =            pgf90 -Minline

or

FC =            pgf90 -Mchkptr

Same error, and no explanation…

Hi benj63,

Which version of cnvgrib are you using? In looking at the latest version (1.1.2) it appears that they have fixed the Jaakko’s problem by allocating gfld%list_opt before passing it to gdt2gds (See line 87 of cnv21.f).

If you are using the latest version, where does the seg fault occur?

  • Mat

Yes, I’m using the version 1.1.2 of cnvgrib.

How can I see where the segmentation fault appears ? Do I have to add special flags in the makefile ?

Thank you

cnvgrib-1.1.2/cnvgrib -g21 gfs.t00z.pgrb2f00 gfs.1
Segmentation fault

Compile the program using “-g” and then run using the PGI debugger, i.e. ‘pgdbg -text cnvgrib’. (Note -text puts the debugger into text mode instead of the GUI.) Next, type ‘run’ followed by the command line arguments for cnvgrib. Once the program seg faults, type ‘where’ or ‘stacktrace’.

Note that you can follow what Jaakko did in the original post.

Thanks,
Mat

Apologies for dredging up an old thread but I’m having problems getting cnvgrib to work on a 64-bit machine and would welcome any help.

As with the previous posters, I am able to successfully compile cnvgrib but when I try to convert a GRIB2 file to GRIB1 I get a segmentation fault. I can, however, convert a GRIB1 file to GRIB2 and then convert this back to GRIB1.

I am using version 1.1.4 of cnvgrib with the 6.0 compiler on an x86-64 machine running RHEL4. I have the stack size set to unlimited.

Here is the output from the debugger;

I have successfully compiled the code on a 32-bit machine but would prefer not to rely on having to use that as a build-machine for our other 64-bit machines.

Any help would be much appreciated.

Hi Graham,

We just tried 7.1-1 with version 1.1.4 and run converting grib1 to glib2 and vice versa with example med.grib[1,2] data from http://www.opc.ncep.noaa.gov/grids/data/latest and it seems to run OK.

Can you provide us the data input you use? Did you try out 7.1-1 release? There could be some bug in 6.0 that we fix in the latest release. What optimization flags did you use, perhaps lower optimization might help.

I am running into a very similar problem seen here, using RHEL4 x86-64 using the 7.1-1 release. I am using -g flags and removed the optimization flags trying to get it to work. I can convert “grib1 to grib2” but not “grib2 to grib1”(which is what I really need) I am using the grib2 gfs model datasets from the NCEP server. An address for a specific file is: ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.2007102312/gfs.t12z.pgrb2f00
When I run the program in the pgdbg, I get the error:
*** glibc detected *** double free or corruption (out): 0x0000002a95c90010 ***
Signalled SIGABRT at 0x3B8CF2E21D, function __GI_raise, file interp.c

Any ideas?? Any help would be greatly appreciated…

Hi Aaron,

I suspect that cnvgrib or libraries/include files(jasper,w3lib,g2lib) are 32-bit applications and has not yet fully ported to 64-bit. I have compiled on 32-bit platform, RHEL3 ,and it runs with your input just fine. I will let you know if I have more information.


Hongyon

13

Thanks for the quick feedback. I did recompile everything in “32 bit mode” and the program does work now. I guess there are still some unresolved 64bit porting issues. Thank you very much!

Aaron

14

Hi, I have the same problem with cnvgrib : -g12 is OK but error for -g21 with a 64 bits linux computer.
Can you tell what programs you compile in 32 bits (only cnvgrib or all the lib needed) and how to compile in 32 bits on my 64 bits machine.
Thanks
Bernard

15

Hi Bernard,

Yes infact you need to compile in 32-bit mode the application need jasper library and jasper is 32-bit library.

To compile with 32-bit compiler on 64-bit machine, there are 2 ways:
Assuming you install a compiler in /opt/pgi.

  1. In csh, setenv PATH /opt/pgi/linux86/7.1-4/bin:$PATH
    in bash, export PATH=/opt/pgi/linux86/7.1-4/bin:$PATH

  2. Set path as you normally set and add -tp k8-32 to a compiler flags.

Hope this helps,
Hongyon

16

If you compile your own jasper, you will need to use -m32 if you use gcc/gfortran to compile.

Hongyon

Thank you for your help. My prog is running fine now

Hi,

Your makefile is not quite right.

should be

$(FC) $(LDFLAGS) -o $(@) $(OBJS) $(LIBS)
