解决了
我在从 OpenSUSE 存储库设置 infiniband 软件时遇到了麻烦。
同一张卡在 SLES12 + Mellanox OFED 堆栈下运行良好。
从 yast 安装包含“infiniband”的所有内容后，我看到 HCA 已启动，并且 ibnodes 等诊断工具显示相关数据：
>ibnodes
Ca : 0x0002c90300a00360 ports 2 "cnode1 HCA-1"
Ca : 0x0002c90300ea8fd0 ports 1 "helper1 mlx4_0"
Switch : 0x0008f1050020096c ports 36 "Voltaire 4036 # spine2" enhanced port 0 lid 17 lmc 0
这里 helper1 是一台 OpenSUSE 机器，cnode1 是一台 SLES 节点。
但当谈到动词时，我得到：
>ibv_devinfo
No IB devices found
因此，我无法让 MPI 与 infiniband 一起工作。
我是否缺少一些中间层，或者 libibverbs 组件是否需要一些额外的配置？
谢谢！
UPD：zypper 和 lsmod 的更多输出：
以下是从 Leap 42.2 存储库安装的软件包：

UPD2：正如 Derek Mitchell 所写，我可以在 SLES+Mellanox OFED 中看到服务 openibd：
>service openibd status
openibd.service - openibd - configure Mellanox devices
Loaded: loaded (/usr/lib/systemd/system/openibd.service; enabled)

Leap 42.2 中没有这样的服务，但是有 rdma 服务：
service rdma status

无论如何，ibv_devinfo 仍然找不到 connectx-3 卡。
UPD3 因此问题是由 Leap 42.2 主存储库不包含 libmlx4-rdmav2 包引起的，而 mlx4 是 connectx-3 HCA 的驱动程序。
添加 Factory OFED 存储库后
zypper addrepo http://download.opensuse.org/repositories/OFED:Factory/openSUSE_Leap_42.2/OFED:Factory.repo
安装 libmlx4-rdmav2 并将所有其他 infiniband 包降级为工厂版本后，我让 ibv_devinfo 开始工作。

答案1
我在 42.1 版本上为我的 VOLTAIRE 410-4EX (mthca) 卡做了以下操作：
zypper install opensm ibutils ibutils-devel infiniband-diags infiniband-diags-devel libibcm1 libibverbs-devel libibverbs-runtime ibacm libibcm1 libmthca-rdmav2 rdma tvflash libibnetdisc5 ibsim qperf
然后：
systemctl enable openibd
systemctl start openibd
