| Summary: High-performance parallel I/O with the NetCDF scientific data format | |
NetCDF is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. Parallel netCDF (PnetCDF) is a library providing high-performance I/O while still maintaining file-format compatibility with NetCDF by Unidata. This package contains the mpich version of utility functions for working with NetCDF files.

https://github.com/Parallel-NetCDF/PnetCDF/blob/checkpoint.1.12.3/RELEASE_NOTES
* New optimization
+ Improve the performance when nonblocking requests contain
more than one record.
* Update configure options
+ Retire configure options `--enable-netcdf4` and
`--enable-adios`, as there are already options
`--with-netcdf4` and `--with-adios`.
* Updated utility program
+ Replace the definition of "difference ratio" used in utility
programs `cdfdiff` and `ncmpidiff`.
+ Utility programs `cdfdiff` and `ncmpidiff` now report only
the first variable element that are different or fail to meet
the tolerances.
+ Use the same user-provided tolerant difference and tolerant
difference ratio (through command-line option '-t') to check
all variables.
* Other updates:
+ Add all PnetCDF I/O hints to the inquired MPI info object
returned by API `ncmpi_inq_file_info()`.
* Bug fixes
+ Fix a bug in utility program `ncvalidator` for the case when
there is no record written, but both fixed-size and record
variables are defined.
+ Fix configure bug of setting environment variable `SEQ_CC`
to the sequential `CC` extracted from `MPICC`.
+ Fix a bug when C function `truncate` is not available.
Argument `fh` of `MPI_File_close` is a pointer.
+ When using an MPI compiler whose Fortran feature was
disabled, the MPI Fortran constants and datatypes may not
be defined in the header file `mpi.h`.
* Issues with NetCDF library
+ Test program `test/nc4/tst_rec_vars.c` fails to run when
using NetCDF 4.8.0 and 4.8.1.
* Clarifications
+ Nonblocking APIs have yet to support subfiling feature.

* Fri Feb 26 2021 Christian Goll <cgoll@suse.com>
- Update to version 1.12.2:
* Updated utility program
* ncvalidator now reports the name of variable that violates the NetCDF
limitation on large variables for CDF-2 files
* add corrupted file bad_large_fixed_var.nc2 that contains one large
fixed-size variables that is not defined last
* add corrupted file bad_large_rec_2_vars.nc2 that contains 2 large record
variables
* add corrupted file bad_large_rec_var.nc2 that contains 1 large record
variable that is not defined last
* add URLs of NetCDF limitations on large variables for CDF-1 and 2 file
formats
* Other updates:
* When calling ncmpi_create() with NC_CLOBBER flag, PnetCDF now calls
access() to check whether file exists first. If the file does not exist,
successive calls to truncate() or unlink() can be skipped.
* Improve detection of HDF5 signature. The HDF5 signature is located at the
beginning of the HDF5 superblock, but the location of HDF5 superblock may
not be at the beginning of the file. It is located at byte offset 0, byte
offset 512, and at successive locations in the file, each a multiple of two
of the previous location; in other words, at these byte offsets: 0, 512,
1024, 2048, and so on.
* Bug fixes
* Fix NC_CLOBBER mode for ncmpi_create() when files are existing symbolic
links. Prior to this release, symbolic links, like other regular files, was
first deleted and then created. This can result in an unexpected outcome,
i.e. the deletion of symbolic link. NetCDF-4 library implements this
differently, by adding O_TRUNC flag when calling open() to truncate the
file to length 0. Historically, PnetCDF did not adopt the same approach
because MPI does not define a similar flag to O_TRUNC and the only way to
achieve the file clobber effect is to through MPI_File_set_size(), which
can be expensive as the function takes an MPI file handler argument, which
requires to open the file first with a call to MPI_File_open().
* Fix a bug of calling Fortran getarg() with the first argument k with a
value > 0 when there is no command-line argument is used. NAG Fortran may
crash the program.

* Mon Nov 09 2020 Egbert Eich <eich@suse.com>
- Enable openmpi4 builds for SLE >= 15-SP2.
* Sat Jul 18 2020 Egbert Eich <eich@suse.com>
- Update to version 1.12.1:
v.1.12.1
- Option '-t' added to 'cdfdiff' to compare variable differences within
a tolerance.
- Make PnetCDF build with OpenMPI 4.
- Fix aliasing bug with -O3.
- String length of I/O hint 'nc_burst_buf_dirname' must be less than
MPI_MAX_INFO_VAL.
v.1.12.0
- Add 'cdfdiff' utility - serial version of 'ncmpidiff' supports classic
NetCDF formats only i.e. CDF-1, CDF-2, and CDF-5.
- 'ncmpidiff' now checks file format versions of two files, and reports
difference if not the same.
- Option '-t' added to 'ncpmidiff' to compare variable differences within
a tolerance.
- MPI info object now includes all PnetCDF hints once obtained form call
to ncmpi_inq_file_info().
- Fix segfault when calling nonblocking API with zero-lenght request and
request ID NULL.
- Per-file thread-safe capability is not supported when using OpenMPI with
ROMIO backend.
v.1.11.2
- Utility program `ncoffsets` updated to skip printing dimension names
if the number of dimensions of a variable is larger than 64.
- Utility program `ncvalidator` updated to be able to repair the file header
to fill in null-byte paddings in the space between the header size and
header extent.
v.1.11.1
- Optimization: When inserting nonblocking requests into the PnetCDF internal pending
queues, queues are now kept sorted (using an insert sort) into an increasing
order of variable starting file offsets.
- Fix ncmpidiff when comparing dimension names of 2 variables between files
whose dimension define orders are different.
- Padding -- NetCDF classic file format specifies null (\x00) byte header padding,
but does not enforce it.
v.1.11.0
- New features
* NetCDF-4 driver -- Accessing HDF5-based NetCDF-4 files is now supported.
- New optimization
* Burst buffer driver is updated to run varn APIs more efficiently.
- New Limitations
* For creating new files, the NetCDF-4 driver in PnetCDF supports only the
classic model I/O operations.
- New APIs
* C++ API `NcmpiFile::set_fill()` is added for setting and inquiring the
fill mode of an opened NetCDF file.
- New PnetCDF hint
* `nc_ibuf_size`: set the size of temporal buffer to be allocated by
PnetCDF internally to pack noncontiguous user write buffers supplied
to the nonblocking requests into a contiguous space.
- Other updates:
* The automatic file layout alignment for fixed-size variables is disabled.
* The internal data buffering mechanism used in the burst buffer driver is
removed.
- Bug fixes
* Fix bug of checking interleaved requests for scalar variables.
* For put and get APIs when buftype is MPI_DATATYPE_NULL, bufcount is
ignored. This is not implemented correctly in blocking put and get APIs.
* ncmpidiff -- when comparing two files that contain record variables but
no record has been written.
* ncmpidiff -- when comparing two scalar variables, error NC_EBADDIM may
mistakenly reported.
* Fix crash when the MPI communicator used in ncmpi_create or ncmpi_open
is freed by the user after the call and before file is closed.
* Discrepancy from NetCDF library
* No read/write variables in define mode when file format is NetCDF-4.
* Diffrent to nc_set_fill() defined in NetCDF-4, ncmpi_set_fill()
changes fill mode of all variables newly defined in current scope
of define mode.
* Error codes return precedence can be different between NetCDF and
PnetCDF.
- Discrepancy from NetCDF library
* NetCDF-4 allows to read/write variables in define mode when file format
is NetCDF-4, while PnetCDF requires data mode.
* In contrast to nc_set_fill() in NetCDF-4, ncmpi_set_fill() changes fill
mode of all variables newly defined in current scope of define mode.
* Error code precedence may differ between NetCDF and PnetCDF.
- Clarifications
PnetCDF currently does not support Fortran default integer type set to 8
bytes (option -fdefault-integer-8 with gnu compiler).
v.1.10.0
- New Features:
* A new I/O layer that makes use of burst buffers is added.
- New Optimizations:
* Internal memory management for nonblocking APIs has been improved to
reduce memory footprint.
* Blocking and nonblocking varn APIs have been improved for better
performance and less memory footprint.
* on noncontiguous layout in user buffer use the user buffer directly
in MPI-IO calls when neither byte-swap nor type-conversion is required
to reduce memory footprint.
- New APIs:
* ncmpi_flush() flushes data buffered by PnetCDF to the destination
file system.
- API semantics:
* ncmpi_put_vard and ncmpi_get_vard APIs
+ Allow to write/read two or more variables in a single call.
+ When argument filetype is MPI_DATATYPE_NULL, request is
considered zero-length.
+ Limitation of vard APIs: element data type of filetype must
conform with variable external NC data type.
+ element data types of all variables accessed in filetype
must be the same.
+ buftype must contain only one same element data type if
it is used to read or write multiple variables from file.
- New error codes:
* NC_EFLUSHED when request got flushed before when calling ncmpi_cancel().
* NC_EBADLOG when burst buffer log files are found corrupted.
- New hints:
* nc_in_place_swap; enable/disable in-place byte swap on Little
Endian architectures.
* nc_burst_buf -- to use the burst buffering feature.
* nc_burst_buf_dirname -- directory where internal log files
for burst buffer will be stored.
* nc_burst_buf_del_on_close -- whether log files should be
deleted when closing NetCDF file.
* nc_burst_buf_flush_buffer_size -- Amount of memory allowed by
users to allocate when flushing the burst buffer log files.
- Rutime environment variable
* PNETCDF_RELAX_COORD_BOUND set to 0 to disable or 1 to enable
more relaxed boundary check for argument start.
- Utility programs:
* ncvalidator adds a new option -t to turn on tracing mode.
- Other updates:
* Add a check for NC_EUNLIMIT in API ncmpi_open to detect whether two or
more unlimited dimensions are defined to detect a corrupted file.
- Bug fixes:
* Fix type_create_subarray64() for case when some dimensions of the global
array is larger than 4G and oldtype is not MPI_BYTE.
* Fix the bug that writing scalar attributes of type NF_INT64 was
mistakenly casted to NF_INT.
* Fix calculation of new record number in put_vard API.
* Fix calculation of growing size of nonblocking request queues to
include the number of records of a record variable, as such request is
split into multiple additional requests, one for each record.
* Remove freeing name object because NC_ENULLPAD is not a fatal error.
* Add a check against NULL before freeing Member "value" of NC_dimarray,
NC_attrarray, and NC_vararray when reading from file where respective
tags are corrupt.
- Conformity with NetCDF library
* Attribute _FillValue of any NC data type may be put to global variable
NC_GLOBAL for all classic files.
v.1.9.0
- New optimizations:
* use hash functions for faster attribute name lookup.

* max number of files to be opened simultaniously is now 1024.
* maximum number of variable dimensions (NC_MAX_VAR_DIMS) is now
2147483647.

2147483647.
* maximum number of variables per file (NC_MAX_VARS) is now
2147483647.
* maximum size of of single put/get request or aggregate size
if non-blocking request per MPI process is INT_MAX.
- New constants:
* NC_FORMAT_UNKNOWN, NF_FORMAT_UNKNOWN, NF90_FORMAT_UNKNOWN will be
returned on ncmpi_inq_file_format if file is unrecognizable.
* NC_MAX_NFILES, NF_MAX_NFILES, NF90_MAX_NFILE define max number
of files that can be kept open my an MPI process.
- API Syntax change:
* Argument fill_value of ncmpi_def_var_fill is 'const' now.
- Semantic updates:
* Calling ncmpi_end_indep_data() in collective data mode no longer
considered illegal.
* For CDF-5 files, the maximum size of a variable or a variable's record
is NC_MAX_INT64-3.
* on inconsistent create/open among processes, the modes on all processes
will be replaced by rank 0's mode. NC_EMULTIDEFINE_CMODE or
NC_EMULTIDEFINE_OMODE will returned on processes disagreeing with
rank 0's mode.
* ncmpi_inq_nreqs() allows argument nreqs to be NULL.
* ncmpi_inq_buffer_usage() & ncmpi_inq_buffer_size() allows argument
usage to be NULL.
* New error codes: + NC_EMAX_REQ, NF_EMAX_REQ and NF90_EMAX_REQ
+ NC_ENULLPAD, NF_ENULPAD and NF90_ENULPAD
- Utility programs:
* ncmpivalid renamed to ncvalidator
- Update:
* Update UTF8 encoding utility to use utf8proc library version 2.1.0.
* Add quiet mode command-line option "-q" to utility program ncvalidator.
* Add an internal check for whether the file starting offsets of all
variables are in an increasing order as the variables defines.
- Bug Fixes:
* Fix a bug in nonblocking APIs when two separate nonblocking requests that
can be coalesced into a contiguous MPI fileview or buffer type but the
coalesced length becomes too big.
* Fix a bug in nonblocking APIs when one request's access region covers
more than one other non-interleaved requests.
* Fix a bug in string parsing the environment variable PNETCDF_HINTS and
print warning messages when hint strings are ill-formed.
* Fix a bug in F90 APIs for reading and writing scalar variables, i.e.
number of dimensions is zero.
* Fix a bug that fails to do byte-swap when retrieving user-defined fill
values.
- Conformity to NetCDF:
* API ncmpi_open now checks the number of large variables that is legal
for CDF-1 and CDF-2 files.
* Add checking for error code NC_ELATEFILL.
* No longer disallow _FillValue for global variable NC_GLOBAL.
* Don't turn fill mode on/off automatically when putting/deleting _FillValue
attribute. This restores consistency with NetCDF.
* PnetCDF can no longer be built on 32-bit machines if using OpenMPI
versions 2.0.2 and 1.10.6 and earlier versions.
- Clarifications:
* External numerical data types can no longer be type casted to NC_CHAR
type upon reading/writing. Only legal APIs the read/write a NC_CHAR
variable are the '_text' APIs.
New translations of internal data types to MPI data types - check release
notes for a table.
v.1.8.1
- Fortran parameters NF_MAX_DIMS, NF_MAX_ATTRS, NF_MAX_VARS, and NF_MAX_NAME
have been fixed to conform with their corresponding C constants.
v.1.8.0
- Copy fill values to data elements that cause out-of-bound error (i.e.
NC_ERANGE.)
New macros added to pnetcdf.h, to indicate the configurable options that
were enabled/disabled. These macros are: PNETCDF_ERANGE_FILL,
PNETCDF_SUBFILING, PNETCDF_RELAX_COORD_BOUND, and PNETCDF_DEBUG_MODE.
- Detect HDF5 file format:
* ncmpi_inq_file_format reports NC_FORMAT_NETCDF4 on HDF5 signature.
* 'ncmpidump' checks for HDF5 format when -k option is specified.
* ncmpi_open checks for HDF5 signature and returns NC_ENOTNC3 error.
- New API:
* ncmpi_strerrno, nfmpi_strerrno, nf90mpi_strerrno return the string name
of a NC error code.
* ncmpi_inq_path, nfmpi_inq_path, nf90mpi_inq_path for inquiring file
pathname used when open/create the CDF file.
- Optimizations:
* Use of Bernstein hash for checking if variable or dimension name is used
already.
* Storage of nonblocking requests.
- Changed syntax:
* ncmpi_cancel can now be called in define mode.
- New error codes: NC_EPENDING, NC_EINVAL_OMODE, NC_EMULTIDEFINE_CMODE for
both C and FOTRAN functions.
- New error code precedences when multiple errors in API argument detected.
* Utility pnetcdf-config to display build configuration.
- Semantic changes:
* For collective APIs, the following errors are considered fatal:
NC_EBADID, NC_EPERM, NC_EINDEFINE, NC_EINDEP, and NC_ENOTINDEP. Once
detects these errors the calling APIs return immediately.
* Consistency check for header data (defining dimensions, variables, and
attributes) is moved to individual APIs and only enabled when safe mode
is enabled.
* For CDF-5 files, regular NC_ERANGE check is performed in PnetCDF for all
APIs that access NC_BYTE variables. For CDF-1 and 2 files, PnetCDF still
honors that exception.
* Error code NC_EPENDING will be returned when pending requests are
detected at the file close.
* API ncmpi_set_default_format is changed to an independent API.
