代码实现介绍

本样例简单验证了MemCache相关接口

如果编译选择CANN依赖

本样例需要在npu环境下编译运行

首先,请在环境上提前安装NPU固件驱动和CANN包(环境安装参考链接)

当前HDK固件驱动需要使用特定版本(社区版HDK下载链接)

安装完成后需要配置CANN环境变量 (参考安装Toolkit开发套件包的第三步配置环境变量)

运行样例前请先编译安装 memfabric_hybrid的run包，默认安装路径为/usr/local/,然后source安装路径下的set_env.sh

memfabric_hybrid参考安装命令

bash memfabric_hybrid-1.0.0_linux_aarch64.run # 修改为实际的安装包名
bash memcache_hybrid-1.0.0_linux_aarch64.run  # 修改为实际的安装包名
source /usr/local/memfabric_hybrid/set_env.sh
source /usr/local/memcache_hybrid/set_env.sh

编译样例程序

在当前目录(memcache/example/cpp)执行如下命令即可

mkdir build
cmake . -B build
make -C build

启动元数据服务

export MMC_META_CONFIG_PATH=/usr/local/memcache_hybrid/latest/config/mmc-meta.conf;
export MMC_LOCAL_CONFIG_PATH=/usr/local/memcache_hybrid/latest/config/mmc-local.conf;
mmc_meta_service &

运行

设置大页（注：仅device rdma/host rdma等protocol需要设置）

 cat /proc/meminfo
 echo 2048 | sudo tee /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

编译完成后,会在当前目录生成build/memcache_cpp_test可执行文件执行方式如下,可交互式的执行put，get等操作命令。

root@localhost:/home/memcache_hybrid/example/cpp# ./build/memcache_cpp_test

手动执行put，get，remove

put  1
1
PutFrom result: 0, key: , replicas: 1
put k 1
PutFrom result: 0, key: k, replicas: 1
get k
Checking existence for key: k
GetInto result: 0
Retrieved data hash for key k: 18356023244072079545
remove k
Remove result: 0 for key: k
exit
Exiting program.
