Applications
Scyld ClusterWare is fully compatible with RedHat Enterprise Linux, supporting a huge variety of applications from all HPC disciplines such as Mechanical Computer-Aided Engineering (MCAE), Life Sciences, Computational Fluid Dynamics, Financial Services, Energy Services and Electronic Design Automation (EDA). Application Notes for applications such as ANSYS®, FLUENT®, LS-Dyna®, Blast, Matlab® and Schrodinger® (Prime/Glide/Jaguar) are available for customers through Penguin Computing's Support Portal.
Resource Managers and Schedulers
Scyld ClusterWare includes the resource management/scheduling solution TORQUE and is compatible with many other popular schedulers. TORQUE is an open source resource manager/scheduler providing control over batch jobs. Originally based on the PBS project, significant advances in the areas of scalability, fault tolerance, and feature extensions have been incorporated. The version of Torque shipping with Scyld ClusterWare is fully supported by Penguin Computing. Scyld ClusterWare also supports other resource managers/schedulers e.g. Sun Grid Engine", Altair PBS Pro", Platform LSF".
For customers with specific requirements such as the need for a customizable a web portal for job submission or sophisticated scheduling policies Penguin Computing offers the workload management solution Scyld TaskMaster™. TaskMaster is a Scyld specific adaptation of the Moab scheduler from Cluster Resources Inc.
Tools and Libraries
For the development of distributed MPI based applications Scyld ClusterWare includes optimized versions of the MPI libraries MPICH, MVAPICH, LAM and OpenMPI, built for common compilers. These modified MPI library implementations take advantage of Scyld ClusterWare's efficient process creation and management. Distributed applications linked against Scyld ClusterWare's MPI libraries can be started without depending on remote execution services. They are launched on the least loaded systems in a consistent environment that includes all environment variables set on the master node at startup time.
Scyld ClusterWare supports the GNU development tools (e.g. gcc, g77, gdb, ddd) that are included in the underlying Linux distribution. Compilers from Intel, Pathscale and the Portland Group are available from Penguin Computing. For the optimization of applications Intel's VTune™ and Intel's Trace Analyzer are offered.
Scalable Filesystems
Scyld includes the parallel file system PVFS2. The parallel high performance file systems Lustre from Sun Microsystems and PanFS from Panasas are supported on Scyld ClusterWare.
Monitoring
Scyld ClusterWare provides graphical tools for monitoring the configuration and resource utilization on compute nodes. Scyld ClusterWare also includes an optimized version of Ganglia, an industry standard, scalable, distributed monitoring system for high-performance computing clusters. Scyld BeoStatus provides information on the current resource utilization in the cluster, Ganglia allows users to view live or historical statistics (such as CPU load averages or network utilization) for all machines that are being monitored. True to the philosophy of minimizing overhead on compute nodes Scyld ClusterWare's Ganglia implementation does not utilize local agents on compute nodes. With Scyld ClusterWare resource information for all compute nodes is already aggregated on the master node. Scyld ClusterWare's Ganglia retrieves the aggregated resource information from the master.
