示例1: remove_lru
/// Removes the least recently used element from the cache
void remove_lru() const{
cachelock.lock();
KeyType keytoerase = lruage.back().key;
// is the key I am invalidating in the cache?
typename cache_type::iterator i = cache.find(keytoerase);
if (i != cache.end()) {
// drop it from the lru list
delete i->second;
cache.erase(i);
}
cachelock.unlock();
}示例2: cusparse_handle
inline cusparseHandle_t cusparse_handle(const command_queue &q) {
typedef std::shared_ptr<std::remove_pointer<cusparseHandle_t>::type> smart_handle;
typedef vex::detail::object_cache<vex::detail::index_by_context, smart_handle> cache_type;
static cache_type cache;
auto h = cache.find(q);
if (h == cache.end()) {
select_context(q);
cusparseHandle_t handle;
cuda_check( cusparseCreate(&handle) );
cuda_check( cusparseSetStream(handle, q.raw()) );
h = cache.insert(q, smart_handle(handle, detail::deleter()));
}
return h->second.get();
}示例3: update_cache
/// Updates the cache with this new value
void update_cache(const KeyType &key, const ValueType &val) const{
cachelock.lock();
typename cache_type::iterator i = cache.find(key);
// create a new entry
if (i == cache.end()) {
cachelock.unlock();
// if we are out of room, remove the lru entry
if (cache.size() >= maxcache) remove_lru();
cachelock.lock();
// insert the element, remember the iterator so we can push it
// straight to the LRU list
std::pair<typename cache_type::iterator, bool> ret = cache.insert(std::make_pair(key, new lru_entry_type(key, val)));
if (ret.second) lruage.push_front(*(ret.first->second));
}
else {
// modify entry in place

// swap to front of list
//boost::swap_nodes(lru_list_type::s_iterator_to(i->second), lruage.begin());
