Issue Building CDO 1.6.4 with PGI 14.7
Added by Matt Thompson over 10 years ago
All,
Today I tried to build CDO 1.6.4 with PGI 14.7 and it threw this error:

Now, first, I'm using mpicc only because netCDF and HDF5 were built with that so I have to build and link with mpicc. That isn't the issue, but I thought I'd head that off at the pass. The version:
$ mpicc -V pgcc 14.7-0 64-bit target on x86-64 Linux -tp nehalem The Portland Group - PGI Compilers and Tools Copyright (c) 2014, NVIDIA CORPORATION. All rights reserved.
Looking at the code:
475 if ( sum > 0 ) {
476 sum = sqrt(sum);
477 #if defined(_OPENMP)
478 #pragma omp parallel for private(i) default(none) \
479 shared(sum,npack,eigenvec,pack)
480 #endif
481 for( i = 0; i < npack; i++ )
482 eigenvec[pack[i]] /= sum;
483 }
484 else
485 #if defined(_OPENMP)
486 #pragma omp parallel for private(i) default(none) \
487 shared(eigenvec,pack,missval,npack)
488 #endif
489 for( i = 0; i < npack; i++ )
490 eigenvec[pack[i]] = missval;
491 } /* for ( eofID = 0; eofID < n_eig; eofID++ ) */
There is nothing really wrong here that I see. I was able to "fix" the code and allow PGI to compile by doing this:
475 if ( sum > 0 ) {
476 sum = sqrt(sum);
477 #if defined(_OPENMP)
478 #pragma omp parallel for private(i) default(none) \
479 shared(sum,npack,eigenvec,pack)
480 #endif
481 for( i = 0; i < npack; i++ )
482 eigenvec[pack[i]] /= sum;
483 }
484 else
485 {
486 #if defined(_OPENMP)
487 #pragma omp parallel for private(i) default(none) \
488 shared(eigenvec,pack,missval,npack)
489 #endif
490 for( i = 0; i < npack; i++ )
491 eigenvec[pack[i]] = missval;
492 }
493 } /* for ( eofID = 0; eofID < n_eig; eofID++ ) */
where I inserted a brace around the "else" structure. Now, I'm mainly a Fortran programmer, but I don't see why that was necessary since the else bit only had one statement. (Note my braces at 485 and 492 are all out of indent because my Vim uses spaces not tabs.) Perhaps PGI reads the standard a bit differently that I think? Not sure what to do with this, but I wanted you (okay, Uwe) to be aware of this.
After that the compile continued and threw another error:

553 nbr_mask[n] = FALSE;

Again, I'm a Fortran coder and in this case, I have no freaking idea what's going on here. Possible compiler bug?
Thanks,

RE: Issue Building CDO 1.6.4 with PGI 14.7 - Added by Matt Thompson over 10 years ago
Okay, some additional testing showed that PGI 13.10 threw the same errors as PGI 14.7. For my next attempt I decided to build with --disable-openmp and, yup, everything compiled just fine.
So, what does this mean? Well, I suppose for the first error (Eof3d.c) that is a case where PGI doesn't see the scope of the parallel for correctly, I guess?
The second one, I'm still a bit befuddled by. Since removing -mp worked, that means somehow one of the OMP pragmas is interfering. I'm also then not too sure if those line numbers (540 and 553) are actually what I think they are. It's possible that, perhaps, there's an interaction with the preprocessor and the number lines are shifted a bit from what's being reported? I'm really confused by that 553 if it's right. "nbr_mask[n] = FALSE;" isn't exactly exciting code...and nbr_mask seems to be dimensioned num_neighbors pretty well.
Finally, I suppose I'll just build with --disable-openmp for the moment. In truth we don't use many of the compute-bound operators in practice and I can always steer someone to one built with gcc or Intel compilers until this is resolved.
Still, any ideas?
Matt

More to add here. I just tried building CDO 1.6.4 with gcc 4.9.1 (OpenMPI 1.8.1) and it does this:

just to report ...
remap_distwgt_scrip.c:303:14: error: expected ‘;’ before ‘,’ token
for ( j = 0, i = 0; i < ndist; ++i )
I also had exactly the same problem compiling CDO v1.6.4 and v1.6.5rc2 with gcc version 4.9.1 (Debian 4.9.1-4), [no Openmpi]; however both CDO versions worked perfectly with gcc version 4.8.3 (Debian 4.8.3-7)
RE: Issue Building CDO 1.6.4 with PGI 14.7 - Added by Uwe Schulzweida over 10 years ago
Thanks for this report! I fixed all CDO problems with the PGI compiler now. A prereleased CDO version is available in the download area.
