abstract = {The use of stand-alone, network-coupled Field
Programmable Gate Array (FPGA) accelerators is
intended to significantly increase the energy
efficiency of HPC applications and thus also of HPC
data centers. A loose coupling between the nodes of
the HPC data center and the FPGAs is established
through the high-speed network of the data
center. This allows greater flexibility in combining
different nodes and accelerators. Both the resulting
energy savings and the increased flexibility through
the network connection, enable the economical use of
FPGAs. This work presents a communication stack to
integrate the so-called Network-attached Accelerator
(NAA) into the HPC data center. A low-level Remote
Direct Memory Access (RDMA) Application Programming
Interface (API) and a high-level Remote Procedure
Call (RPC) API is designed on top of the RDMA over
Converged Ethernet v2 (RoCEv2) communication
stack. The experimental results over 100 Gbps RoCEv2
show that our design and implementation deliver
performance close to the theoretical maximum.},
