Performance and Scalability

Pattern-matching algorithms are usually fast compared with complex statistical models or AI approaches. In particular, Rete and performance-improved variation Leaps recall previous matches and are quite efficient as long as no major changes occur in the input data sets.

Coherence and maintainability of the system degrade rapidly if different developers choose their own schemes to solve these technology issues. Large-scale performance and scalability are determined primarily by how the components are partitioned and distributed across machines and by the nature of communication across machines. 

The performance and scalability of the various techniques is most easily compared in a side-by-side format. With respect to experimental procedures, it is now recognized that many chemical conversions (e.g., formation of C-N or C-C bonds) that were reported to require solid supports with catalytic activity and microwave irradiation (and thus introduced environmental concerns) do not require such auxiliaries or irradiation. They occur exothermally at low temperatures with quantitative yields and without solvent-consuming workups even on a large scale. 

For DSSCs to be marketable and to compete with their inorganic counterparts, fundamental science has to be used to find ways of enhancing cell and module life time and stability without sacrificing performance and scalability. These cells possess a complex structure with disparate materials. Predictive models, validated and improved by cmitinuous feedback from experimental measurements, are needed to decouple and study the many competing mechanisms found in the working cell. With this tool we can discover how cell performance and cell design are related to its material parameters and then systematically search for and arrive at the design specifications that will optimize the cell operation. The need for systematic researeh in DSSC has been stressed by Peter [9].

The process view (behavior or functional view) describes the dynamic aspect of systems as well as the behavior of elements at their intersections to each other and in a defined environment. Relations could be any kind of communication (technical but also man-machine communication etc.) time behavior as well as allocation and structure aspects such as parallelism, distribution, integration, performance and scalability. Activity, sequence or timing diagrams can be used as UML-diagrams. 

Under optimized conditions, the enzymatic process was tested for robustness in multiple mns at 10 kg scale. Three pilot runs at 900 kg (1600 L reactor) scale as well as manufacturing trials at 3.5t (8000 L reactor) demonsuated the consistently high performance and scalability of this enzymatic reaction. A heat-promoted decarboxylation of (S)-3 efficiendy generated ethyl ester (S)-4, a known precursor of Pregabalin 1 [34]. 

Smaller companies tend to have fewer concerns around, for example, system scalability, global WAN performance, and complex systems integration. They are rather more driven by the pure functionality of the ELN that is addressing the specific scientific disciplines of interest. Key drivers in this sector of the market have been medicinal chemistry departments, where the obvious benefits of searching existing reactions by substructure and reaction transformations, the ability to automate stoichiometry calculations, the ability to load spectral information, etc. have made for easy adoption and clear and realizable benefits.

Based on the quantity of data and the complexity of the process, an enterprise operational informatics system must be robust and scalable. It should also integrate with analytical instrumentation such as high performance liquid chromatography (HPLC) MS to verify compound identity. A recent review of HTS informatics provides a compact overview of the key informatics elements of HTS operations and data handling (Ling, 2008). 

In this section, we show that the accuracy of the GPW and GAPW methods can be achieved with high computational efficiency. We illustrate both the serial performance and the scalability on parallel computers using a high-end supercomputer as well as a modern cluster based on a PC-like architecture. 

A storage-area network (SAN) is defined as a specialized, dedicated highspeed network whose primary purpose is the transfer of data between and among computer systems and storage elements. Fibre Chaimel is the de facto SAN standard network protocol, although other network standards, like iSCSI, could be used. SAN is a robust storage infrastructure, optimized for high performance and enterprise-wide scalability.
