iibmalloc

An implementation of malloc() for Message-Passing Programs

Properties

• intended for allocating persistent state and temporaries of Message-Passing Programs
  • does NOT support inter-thread malloc()/free(). To exchange messages between threads, a different (thread-aware) allocator is necessary (thread-aware one will be less efficient, but it won't be used much).
• testing shows it is very fast (when simulating real-world loads, outperforms tcmalloc at least 1.5x; for test results, see an article in upcoming Overload journal scheduled for Aug'18 issue).
  • Uses cross-platform trickery (applies to most of MMU-enabled CPUs) which enables placing information into a dereferenceable pointer (see the same article for funny details).
• supports per-thread serialization (enables serializing thread/(Re)Actor state)
• we're working on optional support for guaranteed-memory-safe C++ (see https://github.com/node-dot-cpp/safe-memory project)

Current Status

• Master branch contains supposedly-usable malloc()/free() (No Known Bugs)
• WIP: postponed free (necessary for memory-safe C++)
• WIP: allocator-level serialization

Getting Started

Clone this repository with modules

git clone --recursive https://github.com/node-dot-cpp/iibmalloc.git

Enter to the poject directory :

cd iibmalloc

Build project

Linux

To build library in Linux

Debug and Release version Run in console

cmake .
make

or

mkdir build
cd build 
cmake ..

And you will get both debug and release library in iibmalloc/build/lib folder

If you want to build test_iibmalloc.bintest.bin just run in console

make  test_iibmalloc.bin

If you want to build test_iibmalloc_d.bin just run in console

make  test_iibmalloc_d.bin

All binaries will be located in iibmalloc/test/build/bin

Run tests

Run in console

make test

It must passed 8 tests.
