I’d like to propose adding features to support mimalloc and jemalloc. Regorus is typically a CPU and memory-bound system, so it makes sense to use allocators that are more efficient than the standard …

Show how to allocate mpi shared memory and pinned memory .
- [x] shared memory
- [x] pinned memory
Examples in `custom_allocations`
HPE seems to be have some cray specific allocations based …

Hi there,
Allocators are not properly propagated on constructors. Two cases I found (not exhaustively):
```
//case A
basic_json(const Allocator&)
{
construct(semantic_tag::none);
}

Early experiments with `jemalloc`, `mimalloc`, `snmalloc`, and `rp_malloc` show potential up to 50% improvements. This is understandable when we optimize to the microseconds.
Currently, `jemalloc` …

Add support for passing a custom allocator with the new [allocator API](https://github.com/rust-lang/rust/issues/32838).

can load the final csvs and produce a diff

may be
```rust
let mut bits = BitVec::from_bytes(&mut mmap[..]);
```
but now (can't be mut)
```
let mut bits = BitVec::from_bytes(&mmap[..]);

We should experiment more with alternative allocators, such as `jemalloc`, to see if we can optimize our allocation behavior and fragmentation in a cheap (essentially free) way.
