Functions

static void Nbnxm::validate_global_work_size (const KernelLaunchConfig &config, int work_dim, const DeviceInformation *dinfo)
 Validates the input global work size parameter.
 
static cl_kernel Nbnxm::selectPruneKernel (cl_kernel kernel_pruneonly[], bool firstPrunePass)
 Return a pointer to the prune kernel version to be executed at the current invocation. More...
 
static cl_kernel Nbnxm::select_nbnxn_kernel (NbnxmGpu *nb, enum ElecType elecType, enum VdwType vdwType, bool bDoEne, bool bDoPrune)
 Return a pointer to the kernel version to be executed at the current step. OpenCL kernel objects are cached in nb. If the requested kernel is not found in the cache, it will be created and the cache will be updated.
 
static int Nbnxm::calc_shmem_required_nonbonded (enum VdwType vdwType, bool bPrefetchLjParam)
 Calculates the amount of shared memory required by the nonbonded kernel in use.
 
static void Nbnxm::fillin_ocl_structures (NBParamGpu *nbp, cl_nbparam_params_t *nbparams_params)
 Initializes data structures that are going to be sent to the OpenCL device. More...
 
void Nbnxm::gpu_launch_kernel (NbnxmGpu *nb, const gmx::StepWorkload &stepWork, const Nbnxm::InteractionLocality iloc)
 Launch GPU kernel. More...
 
static int Nbnxm::calc_shmem_required_prune (const int num_threads_z)
 Calculates the amount of shared memory required by the prune kernel. More...
 
void Nbnxm::gpu_launch_kernel_pruneonly (NbnxmGpu *nb, const InteractionLocality iloc, const int numParts)
 Launch the pairlist prune only kernel for the given locality. numParts tells in how many parts, i.e. calls the list will be pruned.
