This pull request will contain the reference implementations using a PM allocator and post-crash GC (Garbage Collection) to guarantee the crash consistency of the memory allocator and to solve permanent memory leaks. The major purpose of this project is to support people who want to evaluate our RECIPE indexes while involving the overheads of PM allocations and try to apply our indexes to their real-PM applications. The overall directions for this are specified below. We are pleased to receive any suggestions and contributions.
PM allocator
We are planning to make use of the atomic-PM allocator included in libpmemobj for PM allocations.
Post-crash GC
We are considering to implement post-crash GC mechanisms by utilizing APIs provided by libpmemobj to keep track of all the allocated objects. The details about the APIs and examples are officially provided by Intel (link).
