<div>Dear PNETCDF developers:</div>
<div><br>
</div>
<div>I'm attempting to install PNETCDF1.6.1 on a Linux cluster running SLES 11.3. I'm using Intel 15 Fortran and C compilers (no C++), and I'm trying to install for two separate MPI implementations (SGI MPT 2.12 and Intel MPI 5.1.2).</div>
<div><br>
</div>
<div>I'm encountering two problems when I run 'make ptest'.</div>
<div><br>
</div>
<div>1) For both MPI implementations, the large file tests fail with an integer overflow. The error message is:</div>
<div><br>
</div>
<div>
<div>*** Testing large files, slowly.</div>
<div>line 116 of large_files.c: Overflow when type cast to 4-byte integer.</div>
<div>*** Creating large file ./testfile.nc...srun.slurm: error: borgo018: task 0: Exited with exit code 1</div>
</div>
<div><br>
</div>
<div>I reviewed the README.large_files for guidance, and I can confirm that both 'MPI_Offset' and 'off_t' are 8 bytes. </div>
<div><br>
</div>
<div>2) For SGI MPT only, if I disable support for large file tests, 'make ptest' hangs when testing FLASH-IO:</div>
<div><br>
</div>
<div>
<div>make -w -C FLASH-IO ptest</div>
<div>make[2]: Entering directory `/gpfsm/dnb32/emkemp/NUWRFLIB/svn/trunk/builds/parallel-netcdf-1.6.1/benchmarks/FLASH-IO'</div>
<div>mpiexec_mpt -n 4 ./flash_benchmark_io ./flash_io_test_</div>
<div>srun.slurm: cluster configuration lacks support for cpu binding</div>
</div>
<div><br>
</div>
<div>The earlier tests with both single and multiple processes work for SGI MPT. And all tests (again, excluding large file tests) work for Intel MPI.</div>
<div><br>
</div>
<div>I can provide more information (e.g., output from the configure script) upon request.</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
</div>
<div>-Eric</div>
