DTU’s Department of Physics invites tenders for a Linux cluster high performance computer system to be used for floating-point intensive numerical simulations using the researchers’ own developed computer codes as well as commercial codes. The main scientific research focus is on studies of materials and materials design at the atomic scale using quantum-mechanical calculations. The primary quantum-mechanical codes employed are GPAW, VASP, and ADF.

Tenderers should offer very fast processors and compute nodes for such CPU-intensive applications. The compute nodes must be air cooled and have a 1U form factor. Floor space for a row of up to four (4) 42U/60 cm racks will be made available in an existing server room. The terms server and compute node are used interchangeably in this document to designate a single server computer unit.

The cluster must have a High performance and low latency 100 Gbit/s network fabric, in addition to 1 Gbit/s Ethernet networks. Pre-existing storage servers use NFS over Ethernet.

The available power will be 30 kW per rack, and therefore each rack should contain at most 32 compute nodes in addition to the network equipment.

The system must be interoperable with a pre-existing Linux cluster named Niflheim whose configuration is described in the web page https://wiki.fysik.dtu.dk/niflheim/Hardware.

The system performance evaluation of offers will be based upon the code benchmark as specified in Appendix 3. The product of the benchmark result numerical value for a single compute node, times the number of compute nodes offered, should be as high as possible.

The total contract value is fixed at DKK 5 000 000. The contract value is inclusive of customs, duties, and all expenses on the part of the contractor but exclusive of VAT. The contract value comprises the tenderer’s fixed price products and services (elements/product types/equipment/services) until the products/services are delivered, installed, tested and put into operation. Tenderers therefore should offer the best high performance computer system within the fixed contract value.
