PetscThreadCommRunKernel3

PetscThreadCommRunKernel version for kernels with 3 input argument

Synopsis

#include "petscthreadcomm.h" 
PetscErrorCode PetscThreadCommRunKernel3(MPI_Comm comm,PetscErrorCode (*func)(PetscInt,...),void *in1,void *in2,void *in3)

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

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.
