A number of new Qlustar features were completed recently and published
together with the latest security updates.
QluMan 12.0.6.0 has the following new capabilities:
- QLUMAN TIMERS [1] present a new Config class assignable to nodes. They
allow for time-based execution of commands on nodes and are easily
configured via the GUI.
- ENHANCEMENTS OF THE SLURM GUI COMPONENT [2]:
* Added on-the-fly job filtering and job grouping.
* Significantly improved mechanism to transfer job data. The QluMan
GUI is now able to smoothly handle thousands of jobs.
- HARDWARE DETECTION INFO for nodes in the GUI Enclosure view [3] now
transparently highlights misconfigurations, helping admins to track
down faulty settings.
- FILTERS IN USER/GROUP MANAGEMENT [4] have been added, making LDAP management
a lot clearer and easier to follow.
Other new features:
- MELLANOX OFED [5] drivers and tools have been included for optimized support
of clusters with newest Infiniband (IB) technology. Qlustar now
automatically detects whether IB adapters supported by the current
Mellanox OFED release are present and activates its drivers if that's
the case. For all other IB hardware, the in-kernel drivers are used.
- GPU DIRECT RDMA [6] support has been added for nodes running Nvidia GPUs
together with IB adapters supported by Mellanox OFED. It provides a
significant decrease in GPU-GPU communication latency and completely
offloads the CPU, removing it from all GPU-GPU communications across
the network.
- The VIRTUALGL image module is now production ready. When used in a
node image, Qlustar can provide 3D remote visualization on nodes with
the required hardware.
