brpc支持GPU Direct RDMA

21

**Is your feature request related to a problem?** **Describe the solution you'd like** 在GPU上训练时使用brpc的RDMA传输，期望使用GDR能力，直接将**RPC请求**写入到GPU的buffer中，再通过cudamemcp或者gdrcopy从GPU上拷贝出协议部分进行解析，以减少CPU和GPU之间的数据传输。 **Describe alternatives you've considered** 进行的尝试： 将block_pool.cpp中的BlockPool替换成了通过cuda分配的显存，但在使用IOBuf时，会在分配出来的内存上进行placement new，  而这导致CPU直接访问显存，产生core dumped 因此，有以下三种想法： 1.修改block_pool.cpp，新增一个ObjectPool用于分配Block的实体，将Block的data指向BlockPool -> 即 Block的实体部分 与...

假设我在第一个任务中修改了一个堆上的变量，或者说一个全局变量，在第二个任务中一定能看到这个变量的修改吗？

多容器场景下BRPC应用RDMA GID索引匹配错误修复

5

**Describe the bug** 目前，BRPC在选择RDMA设备的GID时，其流程是首先通过ibv_query_port获取GID表的大小（gid_tbl_len），进而通过ibv_query_gid从高索引到低索引反向遍历该表，并选择首个可用的GID。 问题在于，当容器需要RDMA能力时，需要ip link add新设备并配置ip，指定ipvlan master为主网卡eth0，系统会动态地向宿主机的RDMA设备GID表中添加新的条目。在单一宿主机上部署多个容器时，每个容器都会向同一张GID表添加其条目。 此时，若用户未显式指定gid_index，BRPC的通用遍历逻辑会扫描整个GID表。由于缺乏容器级别的隔离感知能力，该逻辑可能使一个容器错误地选中属于另一个容器的GID，导致在初始化时报错： ``` W1017 15:55:46.241584 10770 4294969345 src/brpc/rdma/rdma_endpoint.cpp:1237 BringUpQp] Fail to modify QP from INIT to RTR: No such device W1017 15:55:46.241602 10770...
