I have some programming difficulties on multi threaded search.
One problem is that allocating memory in search is a problem
search(alpha,beta,...)
{
SPLIT* p_split;
p_split = new SPLIT;
if(search in parallel)
searchInparallel(...)
else
search()
delete p_split; //here it crashes
}
The error message says "you can only delete memory from *local* heap".
Do threads have their own heap memory?
When i change in to using a split object than using a pointer it works fine.
but i am thinking this is slower than allocating memory when only i need to
split search. what do you suggest?
Another question is do i need to lock/unlock common data for threads
which is a read only type?
Do you block the main(parent) thread when search is split? i have read ('m not
sure though) this may cause a problem but it seems to work fine for me.
thanks in advance
