For a "4 servers" case, the allocation result is

server 0, accumulated workload for this server is 50711832
server 1, accumulated workload for this server is 52251160
server 2, accumulated workload for this server is 51573260
server 3, accumulated workload for this server is 50041932

Using std::hash sometimes does not generate balanced allocation, so just add it as an option.
