\section{Machine Specification}

The performance experiments were run on three different multicore systems to determine if there is consistency across platforms:
\begin{itemize}
\item
{\bf Nasus} AMD EPYC 7662, 64-core socket $\times$ 2, 2.0 GHz, GCC version 9.3.0
\item
{\bf Algol} Huawei ARM TaiShan 2280 V2 Kunpeng 920, 24-core socket $\times$ 4, 2.6 GHz, GCC version 9.4.0
\end{itemize}


\section{Existing Memory Allocators}\label{sec:curAllocatorSec}
With dynamic allocation being an important feature of C, there are many stand-alone memory allocators that have been designed for different purposes. For this thesis, we chose 7 of the most popular and widely used memory allocators.

\subsection{dlmalloc}
dlmalloc (FIX ME: cite allocator with download link) is a thread-safe allocator that is single threaded and single heap. dlmalloc maintains free-lists of different sizes to store freed dynamic memory. (FIX ME: cite wasik)
\\
\\
{\bf Version:} 2.8.6\\
{\bf Configuration:} Compiled with pre-processor USE\_LOCKS.\\
{\bf Compilation command:}\\
cc -g3 -O3 -Wall -Wextra -fno-builtin-malloc -fno-builtin-calloc -fno-builtin-realloc -fno-builtin-free -fPIC -shared -DUSE\_LOCKS -o libdlmalloc.so malloc-2.8.6.c

\subsection{hoard}
Hoard (FIX ME: cite allocator) is a thread-safe allocator that is multi-threaded and using a heap layer framework. It has per-thread heaps that have thread-local free-lists, and a global shared heap. (FIX ME: cite wasik)
\\
\\
{\bf Version:} 3.13\\
{\bf Configuration:} Compiled with hoard's default configurations and Makefile.\\
{\bf Compilation command:}\\
make all

\subsection{jemalloc}
jemalloc (FIX ME: cite allocator) is a thread-safe allocator that uses multiple arenas. Each thread is assigned an arena. Each arena has chunks that contain contagious memory regions of same size. An arena has multiple chunks that contain regions of multiple sizes.
\\
\\
{\bf Version:} 5.2.1\\
{\bf Configuration:} Compiled with jemalloc's default configurations and Makefile.\\
{\bf Compilation command:}\\
./autogen.sh\\
./configure\\
make\\
make install

\subsection{pt3malloc}
pt3malloc (FIX ME: cite allocator) is a modification of dlmalloc. It is a thread-safe multi-threaded memory allocator that uses multiple heaps. pt3malloc heap has similar design to dlmalloc's heap.
\\
\\
{\bf Version:} 1.8\\
{\bf Configuration:} Compiled with pt3malloc's Makefile using option "linux-shared".\\
{\bf Compilation command:}\\
make linux-shared

\subsection{rpmalloc}
rpmalloc (FIX ME: cite allocator) is a thread-safe allocator that is multi-threaded and uses per-thread heap. Each heap has multiple size-classes and each size-class contains memory regions of the relevant size.
\\
\\
{\bf Version:} 1.4.1\\
{\bf Configuration:} Compiled with rpmalloc's default configurations and ninja build system.\\
{\bf Compilation command:}\\
python3 configure.py\\
ninja

\subsection{tbb malloc}
tbb malloc (FIX ME: cite allocator) is a thread-safe allocator that is multi-threaded and uses private heap for each thread. Each private-heap has multiple bins of different sizes. Each bin contains free regions of the same size.
\\
\\
{\bf Version:} intel tbb 2020 update 2, tbb\_interface\_version == 11102\\
{\bf Configuration:} Compiled with tbbmalloc's default configurations and Makefile.\\
{\bf Compilation command:}\\
make

\section{Experiment Environment}
We used our micro becnhmark suite (FIX ME: cite mbench) to evaluate these memory allocators \ref{sec:curAllocatorSec} and our own memory allocator uHeap \ref{sec:allocatorSec}.

\subsection{Memory Benchmark}

Speed benchmark tested memory allocators for their memory footprint.

This experiment was run with following two configurations for each allocator:\\

Configuration 1:

-threadA :  1

-threadF :  1

-maxS    :  500

-minS    :  50

-stepS   :  50

-distroS :  fisher

-objN    :  100000

-consumeS:  100000\\

Configuration 2:

-threadA :  4

-threadF :  4

-maxS    :  500

-minS    :  50

-stepS   :  50

-distroS :  fisher

-objN    :  100000

-consumeS:  100000

Difference between the two configurations is the number of producers and consumers.
Configuration 1 has one producer and one consumer.
While configuration 2 has four producers where each producer has four consumers.

\caption{Memory benchmark results}
\label{table:mem-benchmark-figs}
\end{table}

Results for memory benchmark are shown in 16 figures, two figures for each of the 8 allocators, one for each configuration.
Table \ref{table:mem-benchmark-figs} shows the list of figures that contain memory benchmar results.

Each figure has 2 graphs, one for each experiment environment.
Each graph has following 5 subgraphs that show program's memory usage and statistics throughout the program lifetime.

\begin{itemize}
\item \textit{\textbf{current\_req\_mem(B)}} shows the amount of dynamic memory requested and currently in-use of the benchmark.
\item \textit{\textbf{heap}}* shows the memory requested by the program (allocator) from the system that lies in the heap area.
\item \textit{\textbf{mmap\_so}}* shows the memory requested by the program (allocator) from the system that lies in the mmap area.
\item \textit{\textbf{mmap}}* shows the memory requested by the program (allocator or shared libraries) from the system that lies in the mmap area.
\item \textit{\textbf{total\_dynamic}} shows the total usage of dynamic memory by the benchmark program which is a sum of heap, mmap, and mmap\_so.
\end{itemize}

* These statistics are gathered by monitoring the \textit{/proc/self/maps} file of the process in linux system.

For each subgraph, x-axis shows the time during the program lifetime at which the datapoint was generated.
Y-axis shows the memory usage in bytes.

For the experiment, at a certain time in the prgram's life, the difference betweem the memory requested by the benchmark (\textit{current\_req\_mem(B)})
and the memory that the process has recieved from system (\textit{heap}, \textit{mmap}) should be minimum.
This difference is the memory overhead caused by the allocator and shows the level of fragmentation in the allocator.
