Upgrade RUG Linux Cluster
Working proposal Linux cluster upgrade
- Version 1, 30 august 2003
The Linux Cluster
The purpose of the Linux cluster is to provide users within the university access to large scale computational resources in a cost effective manner. The resource is intended to be beyond that which can be readily achieved by individual groups or institutes. To be cost effective the cluster exploits commodity components and open source operating systems. Part of the system is connected via a high speed network giving the opportunity to perform large computations in parallel.
The following information is available about the current cluster:
Linux cluster upgrade
The current upgrade was planned as part of the initial proposal for the current cluster. It is intended that the new cluster will be based on a similar architecture to the current cluster but will incorporate new components (modern processors and networking possibilities) to give a large increase in capability. In addition, it is intended that the new Linux cluster will play a role in driving elements of the high performance visualization facilities housed within the RC.
X x single CPU compute node, approximately 120 GB scratch space, 1 GB memory
32 x dual CPU compute node, approximately 120 GB scratch space, 2 GB memory
For the CPU type benchmarks are planned with PIV, Itanium (Intel) and Opteron (AMD). X will depend on hardware prices and the available budget (approximately 100-400 nodes).
Compile front ends
Minimal 3 front ends (dual CPU, 2 GB memory). User groups will be divided among the front ends.
Visualization front ends
5 visualization front ends will make it possible to use the cluster in combination with the VR Theater or the Reality Cube. The visualization front ends will have a direct connection to the internal network of the cluster. The graphics cards will be gen locked and connected to the visualization facilities via a video switch.
For each 64 compute nodes one NFS server (dual CPU, 2 GB memory).
All compute nodes are connected by a 1 Gb network, only wire speed switches will be used. The dual CPU compute nodes will have a additional network connection with a fast special purpose network (Myrinet, SCI or Infiniband).
Storage area network
All file servers will be connected to the RUG SAN with a Fiber Channel connection (1 Gb/s). Initially 1 TB will be available. Quota policy will be based om a standard diskquota per user. Projects can request temporally additional space. Back ups are made on the RUG Exabyte tape robot (total capacity 32 TB). Archive facilities are not standard available but can be realized on request.
The Debian version of the Linux operation system will be used. The following software will be available on the front ends:
Portland compilers (C/C++/Fortran)
PBS-pro queing system)
Plus additional software for the different research groups.
The next meeting of scientific board will be 16 september, this working proposal will be on the agenda.
