InfiniBand ak RDMA

Sooy def quiz bi, tontu yi ak leeral yi dañuy feeñ.

1. What does an RDMA-capable bulk data path aim to reduce?
   • Every CPU operation including setup
   • The need to register or protect memory
   • All application failure modes
   • Repeated CPU copying and kernel-path work during buffer transfers
2. How can an RDMA-capable InfiniBand data path reduce bulk-transfer overhead?
   • By compressing every application buffer
   • By offloading transfers and reducing repeated host copying and kernel processing
   • By removing the need for memory permissions
   • By guaranteeing lower latency for every application
3. Lu tollu ci ban yaatuwaayu band la NDR InfiniBand di joxe ci lëkkalekaay bu nekk?
   • 40 Gb/s
   • 100 Gb/s
   • 400 Gb/s
   • 10 Gb/s

   • Format kompresioŋu dencukaay
   • Benn xeetu lëkkalekaayu fiil optik
6. naka la ko InfiniBand di def ba tissu bi baña ñàkk dara?
   • Soo sànnee bépp paket bu yaatu lool
   • Yonnee paket bu nekk ñetti yoon
   • Soo dindi bépp saytu njuumte
   • Jëfandikoo njiitu lëkkalekaay bu lalu ci leble ngir moytu tampon bi fees
7. Why must an RDMA application manage registered buffer lifetime?
   • The adapter needs valid authorized memory while the transfer runs
   • Registration proves the data are correct
   • Buffers never need completion checks
   • Registration replaces all queue pairs
8. Does RDMA mean a CPU never participates in networking?
   • Yes; CPUs are removed from the servers
   • Yes; every control operation is a GPU kernel
   • No; software and CPU work remain for setup and management
   • No; RDMA requires every byte to be copied repeatedly by the CPU
