Detailed Description

A helper class of static methods.

Any PETSc operation that can be performed using the methods in this class, should be.

This ensures a consistent interface in Chaste even when PETSc arguments change between PETSc versions. For example VecDestroy takes different arguments in 3.2, and using PetscTools::Destroy(vec); takes care of this.

void PetscTools::BeginRoundRobin ( )

static

Call at the start of a block of code that should be executed by each process in turn.

Note that this is not reliable for printing output to stdout in an ordered fashion, since on some systems each process may have a separate stdout buffer, and there's no way to force a flush to the underlying output stream. See e.g. http://stackoverflow.com/questions/5182045/openmpi-mpi-barrier-problems for more info.

Where work can be split between isolated processes, it would be nice to be able to do so easily without worrying about collective calls made inside classes such as OutputFileHandler leading to deadlock. This method attempts to enable this behaviour. If the flag is set then AmMaster and AmTopMost always return true, Barrier becomes a no-op, and ReplicateBool doesn't replicate.

isolate

static

Read a previously dumped PETSc object from disk.

Parameters

rVec	a vector
rOutputFileFullPath	where to read the matrix from
rParallelLayout	If provided, rMat will have the same parallel layout. Its content is irrelevant.

void PetscTools::ReplicateException ( bool  flag )

static

Ensure exceptions are handled cleanly in parallel code, by causing all processes to throw if any one does.

Parameters

flag	is set to true if this process has thrown.

static void PetscTools::SetOption ( const char *  pOptionName, const char *  pOptionValue  )

inlinestatic

Set a PETSc option. This is a wrapper for PetscOptionsSetValue, which changed signature in PETSc 3.7.

Parameters

pOptionName	the option name
pOptionValue	the option value

static

Set up a matrix - set the size using the given parameters. The number of local rows and columns is by default PETSC_DECIDE. SetFromOptions is called.

Parameters

rMat	the matrix
numRows	the number of rows in the matrix
numColumns	the number of columns in the matrix
rowPreallocation	the max number of nonzero entries expected on a row A value of 0 is allowed: no preallocation is then done and the user must preallocate the memory for the matrix themselves.
numLocalRows	the number of local rows (defaults to PETSC_DECIDE)
numLocalColumns	the number of local columns (defaults to PETSC_DECIDE)
ignoreOffProcEntries	tells PETSc to drop off-processor entries
newAllocationError	tells PETSc whether to set the MAT_NEW_NONZERO_ALLOCATION_ERR. ** currently only used in PETSc 3.3 and later ** in PETSc 3.2 and earlier MAT_NEW_NONZERO_ALLOCATION_ERR defaults to false in PETSc 3.3 MAT_NEW_NONZERO_ALLOCATION_ERR defaults to true
