jemalloc-configuration-setup

[Anshul Kundra]

Hi,


I have requirement to setup jemalloc for application, the specification is as follows:

1   Allocations  (small, large ) is in terms of MB (2MB, 4MB, .........)

2.  Allocations are always aligned to 2MB granularity
3.  System Page size considered as 2MB (Linux Huge PAGE)
4.  No request comes for allocation size less than 2MB, if such request comes then application will round up the size to 2Mb granularity

Please provide how to do port jemalloc for such configuration, I want to avail jemalloc (small, large) size class  also for above requirement such that
- small size will range from : 2MB, 4MB, 8MB ....... to 16MB
- large size class ranges from 32MB, 64MB, 128 MB
There is no intermediate allocation size i.e (3MB, 5MB etc )

Thanks & Best Regards,
Anshul Kundra
