Detailed Description
Thread-local data.
Contains data local to each thread in an SPMD section.
Field Documentation
| struct mcbsp_util_stack mcbsp_thread_data::bsmp |
The BSMP incoming message queue.
| size_t mcbsp_thread_data::bsp_id |
Thread-local BSP id.
| struct mcbsp_util_stack mcbsp_thread_data::globalsToPush |
Caches the mapSearch results for use with bsp_push_reg requests.
| struct mcbsp_util_stack mcbsp_thread_data::hpdrma_queue |
The communication queue for hpget and hpput requests.
There is only a single queue per thread, since only the active threads knows when all requests to-be are made and thus when the communication can start. This is what makes hp-primitives unsafe; overlapping or neighbouring memory areas can cause data races and false sharing conditions. The main advantage of using the hp queue is that no payload data will be cached.
| struct mcbsp_util_stack* mcbsp_thread_data::hpsend_queues |
The communication queues used for bsp_hpsend requests.
Kept separately from bsp_hpget and bsp_hpput queues since they are handled quite differently.
| struct mcbsp_init_data* mcbsp_thread_data::init |
Initialisation data.
| struct mcbsp_util_address_map mcbsp_thread_data::local2global |
Local address to global variable map.
| size_t mcbsp_thread_data::localC |
Counts the maximum number of registered variables at any one time.
| struct mcbsp_util_stack mcbsp_thread_data::localsToPush |
The push request queue.
| struct mcbsp_util_stack mcbsp_thread_data::localsToRemove |
Keeps track which globals will be removed before the next superstep arrives.
| struct mcbsp_util_machine_partition mcbsp_thread_data::machine_partition |
Stores the machine part allocated to this thread.
Used for nested runs.
| size_t mcbsp_thread_data::newTagSize |
Stores the tag size to become active after the next synchronisation.
| struct mcbsp_util_stack mcbsp_thread_data::profile |
Where to store any profiling statistics.
| struct mcbsp_util_stack* mcbsp_thread_data::queues |
The communication queues used for all DRMA and BSMP communication.
| struct mcbsp_util_stack mcbsp_thread_data::removedGlobals |
Keeps track of which global variables are removed (as per bsp_pop_reg).
| struct mcbsp_util_stack* mcbsp_thread_data::request_queues |
The communication queues used for bsp_get requests.
| struct timespec mcbsp_thread_data::start |
Stores the start-time of this thread.
(Default POSIX timer.)
| double mcbsp_thread_data::superstep_start_time |
The value of bsp_time at the start of the current computation phase.
| struct mcbsp_superstep_stats mcbsp_thread_data::superstep_stats |
Stores statistics on the current superstep.
