Is it safe to disable CacheLocality technique by removing the "unable to load cache sharing info" exception at folly/concurrency/CacheLocality.cpp:L164 ? On our ppc64le machine, the cpu files maybe not as expected on other architectures like x86_64: The impl expects there is file named "shared_cpu...

When using a small_vector with two 4 byte values and a 2 byte size type, the small_vector is 12 instead of 10 bytes under the GNU toolchain. This wastes space and leads to platform inconsistencies. How to reproduce: #include <cstdint> #include <iostream> #include <folly/small_vector.h...

Before addressing my issue I’d like to do some of the prerequisites. Could someone please direct me, scorecard etc?

fbvector uses malloc instead of allocator methods for memory allocations if allocator type is std::allocator<T> (code) malloc usually aligns output data on 16 bytes boundary, but compiler may generate AVX instruction for initialization, such as vmovaps that requires alignment on a 64/128 byte...

The documentation suggests that the iterators contain hazard points to the elements, and the elements will remain accessible while the iterator is alive, even if it is erased from the map: https://github.com/facebook/folly/blob/main/folly/concurrency/ConcurrentHashMap.h#L44 Here is a very simple rep...
