I always think that shared should be use to make variable global
across threads (similar to __gshared) with some synchronize
protection. But this code doesn't work (app is stuck on _aaGetX
or _aaRehash ):
shared double[size_t] logsA;
void main() {
auto logs = new double[1_000_000];
foreach(i, ref elem; parallel(logs, 4)) {
elem = log(i + 1.0);
logsA[i]= elem;
}
}
But when I add synchronized block it is OK:
shared double[size_t] logsA;
void main() {
auto logs = new double[1_000_000];
foreach(i, ref elem; parallel(logs, 4)) {
elem = log(i + 1.0);
synchronized {
logsA[i]= elem;
}
}
}
