Bright Cluster Manager™ — Linux-Based Cluster
Management Software
Bright Cluster Manager™ greatly simpli-
fies the installation, management and
use of HPC clusters. With Bright Cluster
Manager, a cluster administrator can in-
stall, manage and use multiple clusters
simultaneously without the need for
expert knowledge of Linux or HPC.
Bright Cluster Manager provides the system admin-
istrator with a single system view while offering the
user an excellent environment for High Performance
Computing. It has been designed and proven to scale
Bright Cluster to thousands of nodes, and to run on mission-critical,

Bright Cluster Manager has been installed on
hundreds of clusters, including some of the larg-
est and most complex clusters in the world, and
several TOP500 systems. Bright Cluster Man-
ager is available from resellers across the world
and is supported on most x86-based hardware
brands.
Based on Linux
Bright Cluster Manager is based on Linux and
is available with a choice of pre-integrated, pre-
configured and optimized Linux distributions,
including SUSE Linux Enterprise Server, Red Hat
Enterprise Linux, CentOS and Scientific Linux.
Easy to Install and Use
Bright Cluster Manager is easy to install and
use. It provides a single system view for man-
aging all hardware and software aspects of the
cluster through a single point of control. The
graphical user interface (GUI) streamlines the
administrative workflow by allowing all common
tasks to be performed through one carefully de-
signed interface. Furthermore, all tasks and con-
figuration settings are also accessible through a
scriptable command line interface (CLI).

3. Image Management & Provisioning
Bright Cluster Manager includes a sophisticated im-
age mangement and provisioning system that allows
the cluster administrator to automatically install a fully
functional cluster from bare-metal within minutes.
A virtually unlimited number of images can be cre-
ated and assigned to as many different groups of nodes
as required. Incremental changes to images can be de-
ployed to live nodes without the need for a reboot or
reinstallation. For large clusters, multiple load-balanc-
ing provisioning nodes can be configured on the fly.
Monitoring
With Bright Cluster Manager a comprehensive set of
metrics can be monitored, visualized and analyzed.
Practically all software and hardware metrics available
to the Linux kernel and all metrics available to hardware
management interfaces, such as IPMI or iLO, are avail-
able. Custom metrics can also be defined.
Examples include CPU and GPU temperatures, fan
speeds, SMART information, system load, memory us-
age, network statistics, available disk space and work-
load management statistics.

Cluster Security
Bright Cluster Manager offers a high level of security
which can easily be tailored to local requirements. Se-
curity features include a firewall, certificate-based au-
thentication to the cluster management infrastructure,
secure shell access and automated security updates.
HPC Development Environment
Bright Cluster Manager is not just a cluster manage-
ment environment, it also provides a comprehensive
HPC development environment for serial and parallel
applications.
The environment includes GPU libraries such as
CUDA and OpenCL, HPC middleware such as MPI librar-
ies, OpenMP, Global Arrays, mathematical libraries and
multi-core threading libraries. Development tools such
as compilers, debuggers and profilers are also included.
Environment Modules provide convenient mecha-
nisms for managing different versions of applications,
compilers and libraries simultaneously without creating
compatibility conflicts.
