Can I pragmatically create multiple heaps and set its size for a process in Linux?

Can I pragmatically create multiple heaps and set its size for a process in Linux? I have a need to highly optimize the performance of the back end service/application. With multiple heap, I am hoping I can reduce memory fragmentation, and increase allocation throughput (instead of serialized heap allocation under a single heap per process).I know I can do this in windows but not sure about Linux.
