Presentation of Tendered SystemsM If requested by ECMWF, Tenderers must give at ECMWF a presentation of their proposals. The date of the presentation will be made known following receipt of the tenders, however it is anticipated that it will take place in the week starting 21 February 2000. Alternatives to the Purchase of Desktop Computer SystemsR Tenderers are asked to describe alternatives to the outright purchase of Desktop Computer Systems that they may be able to offer, such as leasing, buy-back, guaranteed trade-in etc. Details on the financial implications should be provided. TECHNICAL REQUIREMENTSRequirements for System SoftwareThe following requirements apply to both the Desktop Computers and the Servers. If the response to a requirement varies according to the Operating System which applies, then this must be clearly indicated. M The Operating System for the 3 types (Servers, Scientific Desktop Computers and Technical Desktop Computers) of equipment need not be the same, but only Unix and/or Linux TM may be tendered. R Unless the Operating System is a version of Linux, Tenderers should indicate the dialect(s) of Unix on which the Operating System is based, and the relevant standards in the field of operating systems to which they are committed. R Tenderers should be aware that ECMWF can only support a limited number of different operating systems, and that the degree of integration, interoperability and commonality between the 3 types of equipment will be a significant factor taken into account during the evaluation of the tenders received. Tenderers should therefore explain any benefits of their proposed solutions with regard to integration, interoperability and commonality. R As described earlier, the Centre has some 50 Administrative Desktop Computers running Microsoft Windows NT 4. Tenderers are asked to describe any benefits that the tendered solution provides in order to improve the integration with Windows NT 4 systems. R Tenderers should provide details of the resource limits enforced by the Operating System of the tendered system. Information should include: the maximum size of a process the maximum number of processes that can exist simultaneously and any other information deemed to be of relevance. R Tenderers should provide a description of resource scheduling, including any options or tools available to configure resource scheduling. R Tenderers should provide a description of the various filesystems (such as normal UNIX filesystems, shared, parallel, journal, memory‑resident etc.) which are supported on the tendered system. Information should include: the maximum size of the filesystem the maximum number of files and directories it can hold the maximum size of any single file or directory resident in it whether the usage of the filesystem can be controlled using quotas file allocation strategies security features inode and data placement and caching filesystem related performance statistics and any other information deemed to be of relevance. M The System must be capable of communicating with all other network attached computer systems at ECMWF, using TCP/IP protocols. M The System must include support for the following TCP/IP services or protocols: telnet, nfs (client and server), ftp, lpr, rpc, rip, smtp, snmp and ospf. M Support for Version 2 of NFS in both client and server mode is required. D Support for NFS Version 3 is desirable. M Support for Network Information Services is required. R Tenderers must describe how and how often new releases of system level software would be distributed to ECMWF. M Whenever new versions of system level software (including compilers and libraries) are released, a minimum of 6 months support for the software release being superseded is required. M For the Server, a batch job subsystem which is interoperable with NQS (Network Queuing System) must be available. Tenderers are asked to provide information about and licensing costs for any such batch job subsystem available for the system. Please indicate whether such implementations are supported by the Tenderer or by a third party. R Tenderers are asked to describe any facilities provided with the system to allow the installation, upgrade and management of the system software and applications from a central system at ECMWF. Any additional costs for such facilities must be stated. R For the Server, Tenderers are asked to describe any backup systems available to allow filesystems to be backed up, preferably to network attached devices, and quote the additional costs involved. Also, please indicate whether an ADSM client is available for the system. Requirements for Programming Languages, Libraries and Software Development ToolsM The following requirements are for the provision of licences for compilers, libraries and debugging tools. It is understood that the costs of licences for such software may depend on the number of licences purchased. Furthermore, the Centre would not necessarily require licences for every system acquired. Therefore the costs for these licences must be given as follows :‑ for 1 licence for 5 licences for 10 licences for 25 licences for 100 licences for 150 licences for a site licence. R If the use of these licences is controlled by a licence manager, full details must be given. M Compilation and development tools are required, including a GUI‑based Software Development environment, for FORTRAN 90, ISO C and ISO C++. M Facilities for interactive source-level debugging and profiling of programs written in any of the programming languages specified in section M are required. M For the Server, support for MPI Version 1 or later (Message Passing Interface) is required. D Support for POSIX threads (also known as pthreads, POSIX standard 1003.1c) is desirable. R Tenderers are asked to describe their support for MPI, OpenMP and any features that are provided to enable programs to easily make use of multiple CPUs, for example auto-parallelization, etc. D A JAVA development environment is highly desirable. M An implementation of Perl5 is required. M Tenderers must indicate to what degree applications can be written in a mixture of Fortran 90, ISO C and ISO C++. Details of the use of the I/O libraries of one language from within another language should be provided. M Support for X11 Release 6 or later is required, for both: X11 server to allow applications to be run on other systems; X11 libraries to allow development of X11‑based applications. M Support for MOTIF Version 1.2 or later, or equivalent, libraries is required, including header files, to allow development of Motif‑based applications. M Support for either OpenGL version 1.2 or Mesa, a 3-D graphics library with an API which is very similar to that of OpenGL, is required. For either solution, GLU 1.2 or later must be included, and the solution must make use of hardware acceleration features within the video subsystem. R Tenderers must provide details of all the components of the OpenGL and/or Mesa implementation. R Tenderers are asked to indicate whether the NAG Fortran-callable numerical library, a product of NAG Ltd, Wilkinson House, Jordan Hill Road, Oxford OX2 8DR, UK, is available for the systems being offered, or, if not, suggest suitable alternatives Requirements for Access to Windows-Intel Software ApplicationsM Tenderers must specify one or more solutions to allow users of the tendered Desktop Computers to access Microsoft Windows-Intel based Software Applications, and describe any constraints that may apply to such solutions. R Tenderers are asked to describe the costs for their specified solution to provide access to Microsoft Windows-Intel based Software Applications as specified in section M above. Requirements for Applications SoftwareR Details are given below of various third-party software applications that ECMWF currently uses. Tenderers are asked to indicate whether the software is available for the system being offered, or, if not, suggest suitable alternatives.
Requirements for SecurityComputer security issues at ECMWF concentrate on the protection of computer systems against unauthorised access and against intended or unintended denial of service access. M A discretionary access control mechanism restricting access to files based on the ownership of the files must be supported. The standard UNIX owner/group/world file protection scheme is considered adequate. R Tenderers are invited to state whether the tendered system has been or is intended to be certified to a recognised security level (e.g. ITSEC). D Encrypted passwords should be stored in a safe place, i.e. in a file that is only accessible to suitably privileged users or processes. D A facility is desirable whereby tasks requiring additional privileges (such as operator, superuser and administrator functions) can be separated so that one individual does not necessarily get all privileges at the same time. R Tenderers should describe which events of relevance to security are logged. D Facilities to extract summary reports from security logs should be available. D A facility to prevent individual users or jobs from monopolizing certain system resources and thereby effectively denying other users service access is desirable. R Tenderers are invited to describe any other security features of the tendered system (such as DCE support or support for Security Dynamic's SecurID cards) that they feel would be of relevance to ECMWF. Where security features use encryption techniques, Tenderers should give details of any restrictions on the dissemination and use of these products imposed by US regulations. Requirements for System Monitoring and Control of ServersD The Operating System should be designed so that, as far as possible, no intervention by operations staff is required to keep it operational at a high level of efficiency in normal circumstances. M Visibility and control must be available to allow the system operator to perform the following tasks: determine the status of all processes in the server determine the status of disk subsystems in the server. M The Operating System must notify the system operator when any hardware component has failed. Requirements for TrainingM Tenderers must quote separately the cost of a training programme which will provide 6 experienced Unix system administrators with sufficient understanding of the internal working of the software and hardware being tendered to enable them to provide effective day-to-day and emergency support. D The Centre would prefer training to be done on the Centre's own premises. The content of the training programme should be described. R Details of other relevant training courses and their cost must be provided. Requirements for DocumentationM On-line documentation and manuals, preferably HTML-based, for the tendered equipment must be provided with the systems. M Three sets of printed manuals etc. of system level documentation must be provided. R Tenderers must state how the printed and online documentation will be kept up-to-date. Computational Performance Requirements for Servers and Desktop ComputersIn this section, the specification for the computational performance requirements for the initial Server and initial batch of Desktop Computers will be given. Note that in this section, “performance requirements” means computational performance requirements; the actual performance required is defined using SPEC values as published by the Standard Performance Evaluation Corporation. Requirements for Technical Desktop ComputersFor a Technical Desktop Computer, the initial performance requirement is approximately that of a mid-range Intel-compatible PC. It is expected that technical developments over the four-year period of the Call-Off Contract will mean that the performance available will increase; ECMWF would therefore expect to procure Technical Desktop Computers with increasing performance over the period at similar or reducing costs. M The Technical Desktop Computer must have a performance level of at least 15 SPECint95 and 15 SPECfp95. Requirements for the Server and Scientific Desktop Computers over the four-year periodFor Scientific Desktop Computers, the performance requirements are driven by the resolution of the forecast model used on the Centre’s Supercomputer Systems, since this is the major factor in determining the time taken to visualize model output. The resolution of the forecast model will increase over the period of the Call-Off Contract, and the consequences of this increase in resolution over the four-year period can be seen in Table 1 below which shows the required CPU performance.
Table 1 Requirements for the Server and Scientific Desktop Computers During the First YearThe Centre understands that, at least initially, the required performance may not be available in a cost-effective manner from a single-CPU Desktop Computer, but a multi-CPU Desktop Computer may be able to provide the computational power required. In addition, the Centre believes that the application requiring this power will scale almost linearly, for 2 CPUs. Therefore, for the purposes of this procurement, the SPECint95 and SPECfp95 values for a single CPU Desktop Computer may be multiplied by the number of CPUs offered (i.e. aggregated) in order to meet the final values required. In addition, for the first year, the performance of the Scientific Desktop Computers may be reduced, provided the performance and memory of the Server is increased correspondingly, as described below. This increase has been calculated to compensate for the lower performance of 25 Scientific Desktop Computers, although this may not be the actual number of Scientific Desktop Computers purchased during the first year. The following table and formulae define the minimum requirements for Scientific Desktop Computers and the relationship between the performance of Scientific Desktop Computers and that of the Server.
Table 2 If the SPECint95 of the offered Scientific Desktop offered is XintDT and the SPECfp95 of the offered Scientific Desktop is XfpDT (these values must be between the values specified in Options A and B) , then the required SPECrate_int95 of the Server is XintS and the required SPECrate_fp95 of the server is XfpS as defined by the formulae 
M Option A in Table 2 defines the preferred level of performance for a Scientific Desktop Computer and the corresponding Server performance required. Option B defines the minimum level of performance which could be accepted provided that the Server has at least the increased level of performance specified. The Tenderer must offer a Scientific Desktop Computer and corresponding Server within the limits specified in Options A and B. D It is desirable for Tenderers also to offer one or more options for Scientific Desktop Computers, with performance levels between the limits specified in Options A and B, and corresponding Servers with performance at least that defined by the formulae above. M The Server must have a memory of at least 16 gigabytes. However, if the SPECrate for the Server is increased as described above in order to allow a Scientific Desktop with a lower SPECint95 or SPECfp95 value, then the Server memory must be increased in proportion using the same principle as used for the SPECrates, up to a possible maximum of 19 gigabytes. D It is highly desirable for the Server offered to be a single system, rather than a cluster of two or more systems. M If the offered Server is a cluster of two or more systems, then each system must be capable of accessing filesystems which are shared within the cluster with I/O performance levels similar to those which can be obtained using filesystems on local disks. Future Requirements for Scientific Desktop ComputersR The Tenderer is asked to describe the increase in computational performance for both Scientific Desktop Computers and Servers which they expect to be available during the 4-year period of the Call-Off Contract, and to comment on how they could meet the requirements for future Scientific Desktop Computer performance as described in Table 1 above. Requirements for Video Subsystems in Desktop ComputersM The tendered systems must support at least 1280 x 1024 resolution with TrueColor (24-bit colours) at 72 Hz vertical refresh rates.
