XCACHE
Introduction
xcache is based on ccache. It can store the outputs of compile into remote servers.
It consists of several components:
- xcache
A new in-memory database which has high efficiency. All the outputs of compile will be stored in it.
- xcache_client
It's just the ccache with the capability to communicate with the xcache.
- xcache_monitor
The monitor of the xcache.
How to build
cd server && make -j
cd client && ./autogen.sh && ./configure && make -j
xcache and xcache_monitor under the directory of server
xcache_client under the the directory of server
How to use:
Single Mode
- Setup the xcache on remote server which is 127.0.0.1. We will run:
xcache -d -c -p 20190 -m 1
The parameter -d means to run as a daemon.
The parameter -c means to generate a core file when xcache crashed.
The parameter -m 1 means to set the original memory of the database to 1G.You can change the value by yourself.
The parameter -p 20190 means to set the port to 20190. You can change the value you like.
You can run xcache -h to see another parameters available.
- Setup the xcache_client, Please run any one of the following commands.
export CCACHE_REMOTE_CONF="--SERVER=127.0.0.1:20190 10"
The value 10 is the xcache_core, please see the distribute cluster mode below.
- Run the ccache to compile
xcache_client gcc test.c -c -o test.o
Distributed Cluster Mode
- Setup the xcache on remote server which is 127.0.0.1. We will run two databases.
xcache -d -c -p 20190 -m 1
xcache -d -c -p 20191 -m 1
The parameter -d means to run as a daemon.
The parameter -c means to generate a core file when xcache crashed.
The parameter -m 1 means to set the original memory of the database to 1G.You can change the value by yourself.
The parameter -p 20190 means to set the port to 20190. You can change the value you like.
You can run xcache -h to see another parameters available.
- Setup the proxy on remote server which is 127.0.0.1. Please run:
xcache -d -c -p 6666 -P
The parameter -P means to change the xcache to a proxy which has a high priority.
- Tell the proxy about the information of the xcache. Please run :
xcache_monitor -S 127.0.0.1:6666["--SERVER=127.0.0.1:20190 10 --SERVER=127.0.0.1:20191 10"]
The format of command is like:
xcache_monitor -S proxy_ip:proxy_port["--SERVER=xcache_ip:xcache_port xcache_core"]
The xcache_core means the power of the database. The one which has bigger xcache_core would store more data than others.
- Setup the xcache_client.
If you don’t use the proxy, please run:
export CCACHE_REMOTE_CONF="--SERVER=127.0.0.1:20190 10 --SERVER=127.0.0.1:20191 10"
If you use the proxy, please run one of the following commands:
export CCACHE_REMOTE_CONF="--PROXY=127.0.0.1:6666"
export CCACHE_REMOTE_CONF=`xcache_monitor -G 127.0.0.1:6666 | tail -1 | grep "SERVER="`
- Run the ccache to compile
xcache_client gcc test.c -c -o test.o
