# 설치 가이드

1. 코드 내려받기

git clone https://github.com/tudordavid/libslock

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd libslock

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Make

보통 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Make Linux/macOS는 보통 기본 설치되어 있습니다. Windows는 별도 설치(예: MSYS2, WSL)가 필요합니다.

make

생성된 빌드 설정을 바탕으로 실제 컴파일을 진행해 실행 파일을 만듭니다.

✅ 에러 없이 끝나면 성공입니다. 생성된 실행 파일을 직접 실행해보세요.

Libslock
=======

This repository provides:
- libslock, a cross-platform interface to atomic operations and other common operations 
- implementations of a number of well-known locking algorithms 
- benchmarks testing the performance of atomic operations and various locking algorithms

The package has been tested on x86_64 Intel and AMD machines, Tilera and Sparc architectures.

A version of this code was used in the paper **"Everything you always wanted to know about synchronization but were afraid to ask"** (accessible here: http://dl.acm.org/citation.cfm?doid=2517349.2522714).

Makefile parameters:

Locking Algorithm
-----------------
Can be passed using `LOCK_VERSION` to the Makefile. `LOCK_VERSION` can take one of the following values:

- `USE_TTAS_LOCKS` - use test-and-test-and-set locks
- `USE_SPINLOCK_LOCKS` - use test-and-set spinlocks
- `USE_TICKET_LOCKS` - use ticket locks
- `USE_HTICKET_LOCKS` - use hierarchical ticket locks
- `USE_MCS_LOCKS` - use MCS locks
- `USE_CLH_LOCKS` - use CLH locks
- `USE_HCLH_LOCKS` - use HCLH locks
- `USE_ARRAY_LOCKS` - use array locks
- `USE_RW_LOCKS` - use read-write locks (not used in paper, not optimized)
- `USE_MUTEX_LOCKS` - use the phtread mutex

Platform
--------
Can be passed using `PLATFORM` to the Makefile; the settings are specific to the platforms we were using (topology, etc.); for other platforms the characteristics can be defined in `platform_defs.h`. The pre-defined platforms are:

- `XEON` - 8 x 10-core Intel sever
- `OPTERON` - 8 x 6-core AMD server
- `NIGARA` - 8-core SparcT2 machine
- `TILERA` - 36-core Tilera machine

Detailed descriptions of these platforms can be found in the paper.

The `OPTERON_OPTIMIZE` option uses some of the Opteron-specific optimizations mentioned in the paper.
Atomic operation to be tested
-----------------------------
For the benchmarks testing atomic operations, this parameter selects the desired operation. Can be passed to the Makefile using `PRIMITIVE`:

- `TEST_FAI` - fetch-and-increment
- `TEST_TAS` - test-and-set
- `TEST_CAS` - compare-and-swap
- `TEST_SWAP` - atomic swap
- `TEST_CAS_FAI` - fetch-and-increment implemented using compare-and-swap

`ALTERNATE_SOCKETS` is used for thread placement on the Niagara; if not set, hardware threads begin by being assinged to the same core; if set threads are disitributed evenly among the cores
