The default storage is compact storage unless the dataset does not meet the < 64KiB limit. Also, if the dataset can have partial IO, then it is contiguous storage. Also, removed 'tab' spacing. All changes should be transparent to the application code.

(PR-123) * Unified similar defines. (PR-124) * Fixed bad assert. (PR-125) * Corrected print format. (CGNS-152, PR-126) * (CGNS-158, PR #128) Fixed heap buffer overflow in cgi_read_ptset In cgi_read_ptset there is made a difference between point set of list and range type. The 'CellListDonor' type was missing in the list of list types and this led to a heap buffer overflow. Added 'CellListDonor' type to list of list types. * (CGNS-159, PR #127) Fixed global-buffer-overflow in ADFI_string_2_C_string. Added a search loop for an early NULL termination of the string passed to ADFI_string_2_C_string in order to prevent global-buffer-overflow when string literals are given as a parameter. * Fixed return stat after calling MPI_Finalize and switched to using a MPI_AllReduce to get the same exit code on all the processes. * Fixed typo, zc should be z3 * Fixed Problems linking Fortran code with 3.3.1 shared library (w/ CMake) (CGNS-118, PR-131) * Do not read elements when computing partial data size. (PR-137) * Disabled the use of H5Pset_file_space_strategy as it is not compatible with HDF5 v1.8 (CGNS-166) * Use correct MPI communicator (PR-140) The `MPI_Allreduce` call in `cgp_parent_data_write()` is using `MPI_COMM_WORLD`, but would be more correct to use the communicator stored in `cgp_mpi_comm` which is set by the client. If the client is not using `MPI_COMM_WORLD` and calls this function, it will hang since not all ranks will be participating in the call. Expanded open-close test to include mixed serial and parallel open and close * Fixed incorrect variable type (PR-143) Minor fix; only applicable if more than 2.1 billion intervals in a range, but does eliminate a compiler warning -- `npt` should be `cgsize_t` * Fixed compiler warnings about the possible loss of data (PR-144) A few variables defined as `int` should be `ssize_t` to avoid potential loss of data on large models. * Corrupted memory when reading int32 connectivity into an int64 dataspace, (CGNS-157) Fixed by changing the cgio_read* calls internal to the MLL to use the cgio_read*_type APIs instead. Created a new cgio_read_block_data_type API with an added data type parameter. * Removed non-standard unlink call * Make static mpi-related variables consistent (PR-139) Currently, it is possible for the `pcg_mpi_comm` to be inconsistent with `pcg_mpi_comm_rank` and `pcg_mpi_comm_size`. The latter two values are set during a call to `cgp_open,` and the first is set during a call to `cgp_mpi_comm.` If the user is using both parallel and serial file access during the same run, they may call `cgp_mpi_comm` multiple times, and the values of `pcg_mpi_comm_rank` and `pcg_mpi_comm_size` will only be consistent with the communicator in `pcg_mpi_comm` if the user calls `cgp_open.` With this fix, all three values (and the `ParallelMPICommunicator`) will always be consistent. Also, if the user does not call `cgp_mpi_comm()` before calling `cgp_open(),` this will be detected, and everything will be consistent. Initialize communicator to MPI_COMM_NULL * miscellaneous code quality improvements and warning fixes. Fortran: -------- * Added missing BUILD_PARALLEL_F. (ref. PR-124) * Fixed cgiof_f03.F90 test passing literal character instead of NULL character in CGIO_CREATE_LINK_F Configuration: ------------- * Fixed HDF5 CMake feature detection for parallel Collective_metadata and H5Pset_file_space_strategy. (PR-138) * Fixed HDF5 feature detection (PR-138) Tools: ------ * Fix cgnstools install (PR-129) Known Problems ============== * See https://cgnsorg.atlassian.net Supported Platforms =================== The following platforms are supported and have been tested for this release.

This well-designed code provision does not hold for cgnslib v3.4.0, which has the same major version number, but significantly different NGON data structures. Thus, the library cannot protect the API users anymore, and unexpected software behaviors might occur. So, if one upgrades to the new cgnslib 3.4.0, they will create CGNS files that will crash when read by other parties who are still using the previous v3.x libraries. This will lead to problems in the community whose aim is to maintain a general, portable and extensible standard that makes it easier to share files between sites and collaborators. ### RESOLUTION Patch 3.4.0 by removing CPEX 41 NGON modification. Reintroduce CPEX 41 in the 4.0.0 release. ### ACTION Removed CPEX 41 NGON modification proposal (CGNS-121); these commits were removed: * Revert "support new ngon layout" This reverts commit 83fc242833d66dd6bb3b6b0f03dc5d71ae59c162. * Revert "fix uninitialized memory for offset." This reverts commit 3fdc9d89ac1b452fc95abd6849f1b07535b500ba. * Revert "fix cgnscheck due to new memory layout with ngon_n and nface_n" This reverts commit 2c09bad0efc4b0042d1b69c3c59309a6f2ea74b9.

Links to the CGNS 3.3.0 source code can be found at: http://cgns.org/download.html User documentation for the current release can be found at: http://cgns.org/CGNS_docs_current/midlevel/index.html For more information, see the CGNS home page: http://cgns.org CONTENTS ============ - New Features - Support for new platforms and languages - Bug Fixes since CGNS 3.2.1 - Known Problems New Features ============== Configuration: ------------------ * Example build scripts for supercomputer systems can be found in src/SampleScripts of the CGNS source code. They include scripts for building zlib, hdf5 (assuming the user does not already have them installed system wide) and a script for building CGNS. All the scripts use autotools; cmake remains untested. * The Fortran compiler environment variable can now be set with "FC", this is the preferred method. * The Fortran compiler flags can now be set with "FCFLAGS", this is the preferred method. If both FFLAGS (which predates FCFLAGS) and FCFLAGS are set then FCFLAGS is ignored. (CGNS-23) Library: ------------ * Replaced the hid_t to double (and vice-versa) utilities to_HDF_ID and to_ADF_ID from a type cast to a function which uses memcpy for the conversion. This is needed for the upcomming release of HDF5 1.10 where hid_t was changed from a 32 bit integer to a 64 bit integer. Should be transparent to user. * Implemented CPEX0039 : To enable with CGNS_ENABLE_BASE_SCOPE * Implemented CPEX0038 : Quadratic Elements for High Order Parallel Library: --------------------- * The default parallel input/output mode was changed from CGP_INDEPENDENT to CGP_COLLECTIVE. * A new function was added for passing MPI info to the CGNS library: cgp_mpi_info (cgp_mpi_info_f) * A new parallel example benchmark program, benchmark_hdf5.c, was added to directory ptests. * The cgp_*_read/write_dataset APIs now excepts non-allocated arrays, or NULL, as valid parameters for the datasets. Additionally, the dimensional arrays, rmin and rmax, can also be NULL. If the data array is NULL and the dimensional arrays are not NULL, then the validity of the dimensional arrays, rmin and rmax, is not checked. For collective parallel IO, this is used as a mechanism to indicated that processes with NULL API parameters will not write any data to the file. * cgp_queue_set and cgp_queue_flush were depreciated in this release. Fortran Library: -------------------- * SUPPORT WAS DROPPED FOR NON-FORTRAN 2003 COMPLIANT COMPILERS. * Configure was changed to check if the Fortran compiler is Fortran 2003 compliant. * The predefined CGNS constant parameters data types were changed from INTEGER to ENUM, BIND(C) for better C interoperability. The users should use the predefined constants whenever possible and not the numerical value represented by the constants. A variable expecting an enum value returned from a Fortran API should be declared, INTEGER(cgenum_t). * INCLUDE "cgslib_h" was changed in favor of using a module, USE CGNS. - This allows defining a KIND type for integers instead of the current way of using the preprocessor dependent cgsize_t. * The user should be sure to declare the arguments declared int in the C APIs as INTEGER in Fortran. The ONLY Fortran arguments declared as type cgsize_t should be the arguments which are also declared cgsize_t in the C APIs. This is very important when building with option --enable-64bit. The test programs were updated in order to conform to this convention. * Assuming the rules in step [enu:int64] were followed, users should not need to use parameter CG_BUILD_64BIT since Fortran's cgsize_t is now guaranteed to match C's cgsize_t. * Fortran programs defining CGNS data types with a default INTEGER size of 8 bytes also then need to compile the CGNS library with the default INTEGER size of 8 bytes. This is independent of whether or not --enable-64bit is being used. For clarification, using --enable-64bit allows for data types (i.e. those declared as cgsize_t) to be able to store values which are too large to be stored as 4 byte integers (i.e. numbers greater than 2,147,483,647). It is not necessary, or advisable (since it waste memory), to have CGNS INTEGER types (types declared int in C) to be 8 bytes; the variables declared as cgsize_t will automatically handle data types that can not be stored as 4 byte integers when --enable-64bit is being used. If the CGNS library was not compiled with a default INTEGER of 8 bytes, but the calling program was, then all integers passed to CGNS with C type int should be declared INTEGER(C_INT). * A new Fortran API was added for determining the CGNS data type of a variable which is interoperable with the C data type. Function cg_get_type(var) type, INTENT(IN) :: var INTEGER(KIND(enumvar)) :: cg_get_type An example of using the new function to automatically specify the CGNS type corresponding to the Fortran data type is, INTEGER, DIMENSION(1:10) :: Array_i CALL cgp_array_write_f("ArrayI",cg_get_type(Array_i(1)),1,INT(nijk(1),cgsize_t),Ai, err) * Removed all parallel flush/queue functions (CGNS-9) * Removed support of "include cgns_f.h", all examples and tests were updated to reflect these changes (CGNS-34) Tools: ---------- - None Bug Fixes since CGNS 3.2.1 release ================================== Configuration: ------------------ * Fixed issue with autotools putting a blank "-l" in "MPILIBS =" when compiling the library using mpi. * Added a new PGI fortran compiler flag fix issue when passing to C varags (CGNS-40) * CMake find_package was added for HDF5, users should use -D CMAKE_PREFIX_PATH=$HDF_DIR to specify a specific version of HDF5. Library: ------------ * Generally improved the performance of cgp_open (cgp_open_f). * Fixed elemtest.c to compile for SunOS 5.12 (CGNS-29) * Fixed parallel issue when not all processors involved in reading/writing (CGNS-51) * Fixed argument being passed to H5Pget_driver in ADFH.c (CGNS-50) * Fixed issue with writing/reading 4D and higher arrays in parallel (CGNS-19) Fortran: ------------ * cgio_link_size_f -- file_len and name_len were changed from cgsize_t to integer to match the C API, CGNS-37. * cgio_is_link_f -- cgio_num was changed from type cgsize_t to an integer to match the C API, CGNS-36. * cgio_is_supported_f -- ier changed from cgsize_t to integer to match the C API, CGNS-35. * Added PGI flag to fix cg_goto_f failing with the PGI compilers on x86_64 platforms, CGNS-40. Tools: ---------- * None Known Problems ================ * Building CGNS with Fortran enabled is not working on Windows. * When building with PGI and gcc compilers it might be necassary to set the environment variables: FLIBS="-Wl,--no-as-needed -ldl" LIBS="-Wl,--no-as-needed -ldl" Supported Platforms ====================== The following platforms are supported and have been tested for this release.
