\VRefrange[Figures]{fig:mem1prod1cons100cfa}{fig:mem4prod4cons100tbb} show 16 figures, two figures for each of the 8 allocators, one for each configuration. 484 Table \ref{table:membenchmarkfigs} shows the list of figures that contain memory benchmark results.485 486 485 Each figure has 2 graphs, one for each experiment environment. 487 Each graph has following 5 subgraphs that show program's memory usage and statistics throughout the program lifetime. 488 486 Each graph has following 5 subgraphs that show memory usage and statistics throughout the microbenchmark's lifetime. 489 487 \begin{itemize} 490 488 \item \textit{\textbf{current\_req\_mem(B)}} shows the amount of dynamic memory requested and currently inuse of the benchmark. 491 \item \textit{\textbf{heap}}* shows the memory requested by the program (allocator) from the system that lies in the heap area.492 \item \textit{\textbf{mmap\_so}}* shows the memory requested by the program (allocator) from the system that lies in the mmaparea.493 \item \textit{\textbf{mmap}}* shows the memory requested by the program (allocator or shared libraries) from the system that lies in the mmaparea.494 \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.489 \item \textit{\textbf{heap}}* shows the memory requested by the program (allocator) from the system that lies in the heap (@sbrk@) area. 490 \item \textit{\textbf{mmap\_so}}* shows the memory requested by the program (allocator) from the system that lies in the @mmap@ area. 491 \item \textit{\textbf{mmap}}* shows the memory requested by the program (allocator or shared libraries) from the system that lies in the @mmap@ area. 492 \item \textit{\textbf{total\_dynamic}} shows the total usage of dynamic memory by the benchmark program, which is a sum of \textit{heap}, \textit{mmap}, and \textit{mmap\_so}. 495 493 \end{itemize} 496 497 * These statistics are gathered by monitoring the \textit{/proc/self/maps} file of the process in linux system. 498 499 For each subgraph, xaxis shows the time during the program lifetime at which the data point was generated. 500 Yaxis shows the memory usage in bytes. 501 502 For the experiment, at a certain time in the program's life, the difference between the memory requested by the benchmark (\textit{current\_req\_mem(B)}) 503 and the memory that the process has received from system (\textit{heap}, \textit{mmap}) should be minimum. 494 * These statistics are gathered by monitoring a process's @/proc/self/maps@ file. 495 496 The Xaxis shows the time when the memory information is polled. 497 The Yaxis shows the memory usage in bytes. 498 499 For the experiment, at a certain time in the program's life, the difference between the memory requested by the benchmark (\textit{current\_req\_mem(B)}) and the memory that the process has received from system (\textit{heap}, \textit{mmap}) should be minimum. 504 500 This difference is the memory overhead caused by the allocator and shows the level of fragmentation in the allocator. 501 502 First, the differences in the shape of the curves between architectures (top ARM, bottom x64) is small, where the differences are in the amount of memory used. 503 Hence, it is possible to focus on either the top or bottom graph. 504 The heap curve It is possible glib, hoard, jemalloc, ptmalloc3, rpmalloc do not use the sbrk area => only uses mmap. 505 506 hoard, tbbmalloc uses more total memory 507 508 ptmalloc3 gives memory back to operating system 505 509 506 510 %mem1prod1cons100cfa.eps … … 513 517 \end{figure} 514 518 519 %mem4prod4cons100cfa.eps 520 \begin{figure} 521 \centering 522 \subfigure[Algol]{
