Condition Variable: a condition on which ULTs are waiting until it is signaled. Execution Stream (ES): a sequential instruction stream that contains one or more work units. Future: a mechanism for passing a value between work units, allowing a work unit to wait for a value that is set asynchronously. Handle: an opaque reference to an Argobots object. Mutex: a synchronization method to support mutual exclusion between work units. Object:

Paper: argobots SM1 in ES1 has one associated private pool, PM11, and SM2 in ES2 has two private pools, PM21 and PM22. PS is shared between ES1 and ES2, and thus both SM1 in ES1 and SM2 in ES2 can access the pool to push or pop work units. PE denotes an event pool. The event pool is meant for lightweight notification. It is periodically checked by a scheduler to

LSM树并不像B+树、红黑树一样是一颗严格的树状数据结构，它其实是一种存储结构，目前HBase,LevelDB,RocksDB这些NoSQL

pmemlog_create() // 创建持久化的log内存 pmemlog_open() // 打开已创建的log内存 pmemlog_nbyte() // 获得某log内存内可以添加多少位的数据，而非多少条记录 pmemlog_append() // 向log内存中append

Write &Read PMEMobjpool pmemobj_create() // 创建持久化内存池 PMEMobjpool pmemobj_open() // 打开已创建的持久化内存池 PMEMoid pmemobj_root() // 得到持久化内存池的根节点 pmemobj_direct() // 得到根节点的指针 pmemobj_persist() // 将单变量进行持久化存储 pmemobj_memcpy_persist() // 将数
