> I am super interested in how you do the comparison. Can you post a patch for the code you have for that? The HashMappedTrie hasn't been really tuned for performance/memory usage, it would be interesting to use your tool to do some investigation (for example, the NumRootBits and NumSubtrieBits can be tuned for memory/performance).
@steven_wu I`ve updated D132548 <https://reviews.llvm.org/D132548> to have a possibility to measure HashMappedTrie. It depends on D125979 <https://reviews.llvm.org/D125979>, D132455 <https://reviews.llvm.org/D132455>, D133715 <https://reviews.llvm.org/D133715>.
In its current state patch does not set NumRootBits, NumSubtrieBits, though such options might be added.
If intel threading building block hashmap is not neccessary - the USE_ITBB should be unset.
if lib cuckoo hashmap is not neccessary - the USE_LIBCUCKOO should be unset.
Command line to run the tool:
/usr/bin/time -f " %E %M " ./check-hashtable --data-set random --num-threads 1 --table-kind hash-mapped-trie --aggregate-data
Any changes/suggestions are welcomed :-)
