示例1: operator
bool operator()( T &v ) {
v = (T)my_count.fetch_and_increment();
if ( (int)v < N )
return true;
else
return false;
} 示例2: operator
void operator () (const tbb::blocked_range<int> &range) const {
int i;
PARTITIONER partitioner;
for (i=range.begin(); i<range.end(); i++) {
//printf("Outer Loop Body[%d<=%d<%d]=[0,%d]\n", range.begin(), i, range.end(), degrees[currentLevelSet[i]]);
#ifdef SEQUENTIAL_INNER
for(int j=0; j<degrees[currentLevelSet[i]]; j++) {
int oldGatek;
int freshNode,currentEdge;
currentEdge = vertices[currentLevelSet[i]]+j;
// let's handle one edge
#ifdef XBOFILE
freshNode = edges[currentEdge][1]; // 0 RTM, value was prefetched
#else
freshNode = edges[currentEdge]; // 0 RTM, value was prefetched
#endif
oldGatek = -1;
// test gatekeeper
oldGatek = gatekeeper[freshNode].fetch_and_increment();
if (oldGatek == 0) { // destination vertex unvisited!
// increment newLevelIndex atomically
int myIndex = newLevelIndex.fetch_and_increment();
// store fresh node in new level
newLevelSet[myIndex] = freshNode;
level[freshNode] = currentLevel + 1;
