1934e1ad211SJed Brown 
1941393a3abSPatrick Sanan   To avoid prepending "PETSC_", say to add custom checks in user code, one can use e.g.
1951393a3abSPatrick Sanan

1984e1ad211SJed Brown   Developer Notes:
1994e1ad211SJed Brown   Getting something that works in C and CPP for an arg that may or may not be defined is tricky.  Here, if we have
2004e1ad211SJed Brown   "#define PETSC_HAVE_BOOGER 1" we match on the placeholder define, insert the "0," for arg1 and generate the triplet
2014e1ad211SJed Brown   (0, 1, 0).  Then the last step cherry picks the 2nd arg (a one).  When PETSC_HAVE_BOOGER is not defined, we generate
2024e1ad211SJed Brown   a (... 1, 0) pair, and when the last step cherry picks the 2nd arg, we get a zero.
2034e1ad211SJed Brown 
2044e1ad211SJed Brown   Our extra expansion via PetscDefined__take_second_expand() is needed with MSVC, which has a nonconforming
2054e1ad211SJed Brown   implementation of variadic macros.

1640659f7ba0SBarry Smith     Collective on comm
1641eca87e8dSBarry Smith 
1642d382aafbSBarry Smith     Input Parameters:
1643659f7ba0SBarry Smith +  comm - the MPI communicator over which the help message is printed
1644d382aafbSBarry Smith .  format - the usual printf() format string
1645659f7ba0SBarry Smith -  args - arguments to be printed

1649d382aafbSBarry Smith    Fortran Note:
1650d382aafbSBarry Smith      This routine is not supported in Fortran.
1651d382aafbSBarry Smith 
1652659f7ba0SBarry Smith    Note:
1653659f7ba0SBarry Smith      You can change how help messages are printed by replacing the function pointer with a function that does not simply write to stdout.
1654659f7ba0SBarry Smith 
1655659f7ba0SBarry Smith       To use, write your own function, for example,
1656659f7ba0SBarry Smith $PetscErrorCode mypetschelpprintf(MPI_Comm comm,const char format[],....)
1657659f7ba0SBarry Smith ${
1658659f7ba0SBarry Smith $ PetscFunctionReturn(0);
1659659f7ba0SBarry Smith $}
1660659f7ba0SBarry Smith then do the assigment
1661659f7ba0SBarry Smith $    PetscHelpPrintf = mypetschelpprintf;
1662659f7ba0SBarry Smith    You can do the assignment before PetscInitialize().
1663659f7ba0SBarry Smith 
1664659f7ba0SBarry Smith   The default routine used is called PetscHelpPrintfDefault().

203050d8bf02SJed Brown +  PETSC_PREFETCH_HINT_NTA - Non-temporal.  Prefetches directly to L1, evicts to memory (skips higher level cache unless it was already there when prefetched).
203163cf1ef0SJed Brown .  PETSC_PREFETCH_HINT_T0 - Fetch to all levels of cache and evict to the closest level.  Use this when the memory will be reused regularly despite necessary eviction from L1.
203263cf1ef0SJed Brown .  PETSC_PREFETCH_HINT_T1 - Fetch to level 2 and higher (not L1).
203363cf1ef0SJed Brown -  PETSC_PREFETCH_HINT_T2 - Fetch to high-level cache only.  (On many systems, T0 and T1 are equivalent.)

247666d79e26SBarry Smith     PETSC_VERSION - This manual page provides information about how PETSc documents and uses its version information. This information is available to both C/C++
247766d79e26SBarry Smith                     and Fortran compilers when petscsys.h is included.
247866d79e26SBarry Smith 
247966d79e26SBarry Smith     The current PETSc version and the API for accessing it are defined in petscversion.h
248066d79e26SBarry Smith 
248166d79e26SBarry Smith     The complete version number is given as the triple  PETSC_VERSION_MAJOR.PETSC_VERSION_MINOR.PETSC_VERSION_SUBMINOR (in short hand x.y.z)
248266d79e26SBarry Smith 
248366d79e26SBarry Smith     A change in the minor version number (y) indicates possible/likely changes in the PETSc API. Note this is different than with the semantic versioning convention
248466d79e26SBarry Smith     where only a change in the major version number (x) indicates a change in the API.
248566d79e26SBarry Smith 
248666d79e26SBarry Smith     A subminor greater than zero indicates a patch release. Version x.y.z maintains source and binary compatibility with version x.y.w for all z and w
248766d79e26SBarry Smith 
248866d79e26SBarry Smith     Use the macros PETSC_VERSION_EQ(x,y,z), PETSC_VERSION_LT(x,y,z), PETSC_VERSION_LE(x,y,z), PETSC_VERSION_GT(x,y,z),
248966d79e26SBarry Smith     PETSC_VERSION_GE(x,y,z) to determine if the current version is equal to, less than, less than or equal to, greater than or greater than or equal to a given
249066d79e26SBarry Smith     version number (x.y.z).
249166d79e26SBarry Smith 
249266d79e26SBarry Smith     PETSC_RELEASE_DATE is the date the x.y version was released (i.e. the version before any patch releases)
249366d79e26SBarry Smith 
249466d79e26SBarry Smith     PETSC_VERSION_DATE is the date the x.y.z version was released
249566d79e26SBarry Smith 
249666d79e26SBarry Smith     PETSC_VERSION_GIT is the last git commit to the repository given in the form vx.y.z-wwwww
249766d79e26SBarry Smith 
249866d79e26SBarry Smith     PETSC_VERSION_DATE_GIT is the date of the last git commit to the repository
