容器的内存申请默认是std::allocator,并没有内存对齐,因此使用STL容器的时候要指定使用Eigen::aligned_allocator用于内存对齐。 std::map< int, Matrix4f, std::less<int>, aligned_allocator<std::pair<const int, Matrix4f> > > my_map_mat4; std::vector<Matrix4f, aligned_allocator<Matrix4f>> my_vecto...

Solved: I am seeing the following code in the cache_aligned_allocator. Does TBB blindly use the cache line size of 128 or does it actually check at
Numpy allocator C-API, see https://numpy.org/doc/stable/reference/c-api/data_memory.html Any other comments? Whilenumpy/numpy#27327works perfectly fine locally, this PR results in a segmentation fault.
Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile- or run-time. The string pointed to by the global variable malloc_conf, the "name" of the file referenced...

Before you decide which is more "effective", you should be crystal clear on how different allocators behave differently: new (and new[]) allocate memory and call the constructor. The memory must be deallocated with delete or delete[]. malloc() just returns a block of memory. It is uniniti...
