# This easyconfig only installs the library of GDRCopy. Please keep in mind
# that GDRCopy also needs the following kernel modules at runtime:
#
# 1. Kernel module for GDRCopy: improves Host to GPU communication
# https://github.com/NVIDIA/gdrcopy
# RPM: 'gdrcopy-kmod', DEB: 'gdrdrv-dkms'
# Requirements: version of GDRCopy kernel module (gdrdrv.ko) >= 2.0
#
# 2. (optional) Kernel module for GPUDirect RDMA: improves GPU to GPU communication
# https://github.com/Mellanox/nv_peer_memory
# RPM: 'nvidia_peer_memory'
# Requirements: Mellanox HCA with MLNX_OFED 2.1
#
# These kernel modules are not listed as system dependencies to lower the system
# requirements to build this easyconfig, as they are not needed for the build.
