PetscThreadCommRunKernel6

PetscThreadCommRunKernel version for kernels with 6 input arguments

Synopsis

#include "petscthreadcomm.h" 
PetscErrorCode PetscThreadCommRunKernel6(MPI_Comm comm,PetscErrorCode (*func)(PetscInt,...),void *in1,void *in2,void *in3,void *in4,void *in5,void *in6)

Input Parameters

comm - the MPI communicator
func - the kernel (needs to be cast to PetscThreadKernel)
in1 - first input argument for the kernel
in2 - second input argument for the kernel
in3 - third input argument for the kernel
in4 - fourth input argument for the kernel
in5 - fifth input argument for the kernel
in6 - sixth input argument for the kernel

Notes

All input arguments to the kernel must be passed by reference, Petsc objects are inherrently passed by reference so you don't need to additionally & them.

Example usage - PetscThreadCommRunKernel1(comm,(PetscThreadKernel)kernel_func,x); with kernel_func declared as PetscErrorCode kernel_func(PetscInt thread_id,PetscInt* x)

The first input argument of kernel_func, thread_id, is the thread rank. This is passed implicitly by PETSc.
