speedyLoc: C library for dynamic memory allocation.

It uses the ideas from LFMalloc (Lock free malloc implementation) and TCMalloc to create a more time and memory efficient approach to
memory allocation in C Language.

Refer to the following literature for understanding implementation of LFMalloc and TCMalloc.

1. Dice, David & Garthwaite, Alex. (2002). Mostly lock-free malloc​. SIGPLAN Notices. 38. 269-280.
2. http://goog-perftools.sourceforge.net/doc/tcmalloc.html

API’s implemented

void *malloc(size_t size);
void free(void *ptr);

Novelty:

1. Fine grained size classes for small sized memory requests.
2. Balance between number of size classes and fragmentation.
3. Mostly Lock free approach to memory allocation to increase parallelism.

Results/Benchmarks

Performance comparison with libc malloc library for 10, 50, 500, 1000 threads. Please refer to docs for detailed benchmarks.

Existing Issues (Future work)

1. High frequency of upcalls.
2. Kernel driver does not support re-routing upcalls based on specific threads.
3. Process can go into a cycle of upcall->kernel->upcall as the number of threads increases.
