Version EL7-20.07

The DGX Software for Red Hat Enterprise Linux 7, EL7-20.07 update, is available. You must enable the update repository in order to obtain this update.

EL7-20.07 supports the DGX A100. For the list of changes and updates for other DGX platforms, see the Version EL7-20.06 chapter.

Important: Installing or updating to EL7-20.07 also updates the installed Red Hat Enterprise Linux 7 distribution to the latest version. If you require use of the Mellanox OpenFabrics Enterprise Distribution for Linux (MLNX_OFED), then before installing or updating to EL7-20.07, be sure that there is a MLNX_OFED package version available that supports the latest Red Hat Enterprise Linux 7 version. If a supporting MLNX_OFED package has been released, then be sure to install it.

R450 Repository

The R450 repository must be enabled for the DGX A100. See the DGX Sotware for Red Hat Enterprise Linux Installation Guide for instructions.

Change Highlights

Software Contents:

The following table provides version information for software included in the DGX Software Stack for Red Hat Enterprise Linux 7.

Note: Unlike the DGX OS shipped with the NVIDIA DGX system, the DGX software stack for Red Hat does not include the Mellanox OpenFabrics Enterprise Distribution (MLNX_OFED) for Linux. This is due to the likelihood of the MLNX_OFED kernel  being out of sync with the Red Hat distribution kernel. This can result in system instability. To use InfiniBand on the DGX system, see the DGX Software for Red Hat Enterprise Linux 7 Installation Guide for instructions.
