IBV_UD_PINGPONG(1)

💖 IBV_UD_PINGPONG 💖

okay bestie, welcome to the ibv_ud_pingpong page — that's section 1 of the user commands manual, and she's a lil InfiniBand UD transport test, no big deal 💅

✨ NAME ✨

ibv_ud_pingpong — a simple InfiniBand UD transport test 🦋

🌸 SYNOPSIS 🌸

ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx
depth] [-n iters] [-l sl] [-e] [-g gid index] HOSTNAME

ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx
depth] [-n iters] [-l sl] [-e] [-g gid index]

so like, you either give her a HOSTNAME and she's the client, or you give her nothing and she's just vibing as the server, periodt ✨

💜 DESCRIPTION 💜

💀 BUGS 💀

the network synchronization between client and server instances is weak, and it does not prevent incompatible options from being used on the two instances. so like, if you and your bestie pass different options, she will simply not stop you, and that's a whole mess 🙈

the method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some systems. no cap, it's giving slightly unhinged. proceed with awareness 💅
