Array accesses

The prediction can be based on discovering patterns. Automatic hardware prefetch methods in modem CPUs bring entire cache lines into the last level cache triggered by cache misses. Based on the recorded history of requests they search for and discover stride patterns, which makes them perfectly suited for linear array accesses but they do not work with random memory access patterns. [Pg.30]

Type A alarm about a runtime error which has unpredictable results. The analyzer reports the alarm and continues the analysis for scenarios where the error does not occur. For contexts where the error definitely occurs, the analyzer reports a definite runtime error and stops the analysis as there is no feasible continuation. Examples are out-of-bound array accesses, or write accesses via dangling pointers. [Pg.87]

The ultrasonic tomograph A1230 was developed to visualize in case of one side access the internal reinforced concrete structure at the depth of 1 m. This device uses 36-elements matrix array. [Pg.911]

For fast access to the two-electron integrals, a fonr-dimensional array migh t be straigh t for ward. Th e four in times of the four diinen -sional array correspond to the four basis function indices, p, v, X, an d a. respectively. However, the four dimen sional array m ay lake a huge mam memtiry or computer disk space even for a mediiim-si/e molecule. Therefore, this may not be practical. [Pg.263]

The memory subsystem on most supercomputers is organized to support maximum performance on loops of stride one, or when the elements of an array are accessed sequentially with no gaps. In general, the stride is defined by... [Pg.89]

The methodological advances just presented have brought the field of nucleic acid force field calculations to a point where results from the calculations can be used with reasonable confidence to aid in the interpretation of experimental data as well as to be used for scientific investigations that are not accessible to experiment. Accordingly, a number of studies based on MD simulations, as well as other methods, have been undertaken to study a wide array of biologically relevant events associated with DNA. A brief overview of some of these efforts follows. [Pg.444]

Deuterioboration is one of the most important recent additions to the array of methods for saturating double bonds with deuterium. The easy accessibility of metal deuterides (lithium aluminum deuteride or sodium borodeuteride) facilitates the in situ preparation of deuteriodiborane which reacts with steroidal double bonds with a high degree of site and/or stereospecificity, depending on the location of the double bond. " ... [Pg.191]

The second major class of protein structures contains structures based around parallel or mixed j8-sheets. Parallel /3-sheet arrays, as previously discussed, distribute hydrophobic side chains on both sides of the sheet. This means that neither side of parallel /3-sheets can be exposed to solvent. Parallel /3-sheets are thus typically found as core structures in proteins, with little access to solvent. [Pg.186]

Contrary to the expectation that a sulfur-containing substituent will be a catalyst poison, a phenylthio group serves as an effective selectivity control element in TMM cycloadditions. A single regioisomer (30) was obtained from the carbonate precursor (31) in good yield. The thermodynamically more stable sulfide (32) is readily accessible from (30) via a 1,3-sulfide shift catalyzed by PhSSPh. A wide array of synthetically useful intermediates could be prepared from the sulfides (30) and (32) with simple transformations (Scheme 2.10) [20]. [Pg.64]

The first total synthesis of erythronolide B (1) by Corey stands as an event of great historical significance in synthetic chemistry it provides a powerful illustration of the utility of Corey s methods of macrolactonization and it demonstrates, in a particularly insightful way, the value of using readily accessible six-membered ring templates for the assembly of contiguous arrays of stereo-genic centers. [Pg.169]

Biological raw data are stored in public databanks (such as Genbank or EMBL for primary DNA sequences). The data can be submitted and accessed via the World Wide Web. Protein sequence databanks like trEMBL provide the most likely translation of all coding sequences in the EMBL databank. Sequence data are prominent, but also other data are stored, e.g.yeast two-hybrid screens, expression arrays, systematic gene-knock-out experiments, and metabolic pathways. [Pg.261]

The field of modified electrodes spans a wide area of novel and promising research. The work dted in this article covers fundamental experimental aspects of electrochemistry such as the rate of electron transfer reactions and charge propagation within threedimensional arrays of redox centers and the distances over which electrons can be transferred in outer sphere redox reactions. Questions of polymer chemistry such as the study of permeability of membranes and the diffusion of ions and neutrals in solvent swollen polymers are accessible by new experimental techniques. There is hope of new solutions of macroscopic as well as microscopic electrochemical phenomena the selective and kinetically facile production of substances at square meters of modified electrodes and the detection of trace levels of substances in wastes or in biological material. Technical applications of electronic devices based on molecular chemistry, even those that mimic biological systems of impulse transmission appear feasible and the construction of organic polymer batteries and color displays is close to industrial use. [Pg.81]

Summing up this section, we would like to note that understanding size effects in electrocatalysis requires the application of appropriate model systems that on the one hand represent the intrinsic properties of supported metal nanoparticles, such as small size and interaction with their support, and on the other allow straightforward separation between kinetic, ohmic, and mass transport (internal and external) losses and control of readsorption effects. This requirement is met, for example, by metal particles and nanoparticle arrays on flat nonporous supports. Their investigation allows unambiguous access to reaction kinetics and control of catalyst structure. However, in order to understand how catalysts will behave in the fuel cell environment, these studies must be complemented with GDE and MEA tests to account for the presence of aqueous electrolyte in model experiments. [Pg.526]
