To understand the importance of strong updates when analyzing object- oriented programs written in memory managed languages we look to the litera- ture to better understand how these programs construct and modify structures on the heap. Results in [5, 7, 37] show that object-oriented programs ...
See offheap.go for all the interesting code. Modify val_t to hold you values, and key_t to contain your keys. Current sample code for three types of keys (int64, []byte, and strings) is provided (see bytekey.go). For the hashing function itself, the incredibly fastxxhash64is used ...
