The current hash_combine caused a ShardingID collision when I ran with 14 nodes on Perlmutter. It looks like the first version that was in Boost. Here's some info on Boost's recent implementation.
These machine views produced the same hash of 1804451222.
MachineView<0=[44:46:1]>
MachineView<0=[41:97:1]>
I updated my branch to use the 64bit version. It might be better to copy their whole implementation, which dispatches to 32 or 64 bits depending on size_t.
