Abstract: Discussed herein are techniques that utilize hierarchical locality information of host machines included in a cluster network for the execution of general workloads. Hierarchical locality information for each host machine of a plurality of host machines is stored. The hierarchical locality information for a host machine identifying, for each locality of a plurality of localities, location information for the locality. Responsive to receiving a request requesting execution of a workload, the hierarchical locality information for the plurality of host machines is obtained and provided (e.g., to a customer) in response to the request.

Abstract: Pyridazino(4,5-b)(1,5)oxazepinone, thiazepinone and diazepinone compounds of formula(I) and their tautomers and the acid-addition salts of all these compounds show memory-enhancing and neuroprotective properties.

Abstract: The present invention relates to novel, antiarrhythmically active phenoxyalkylamine derivatives possessing a double point of attack. More particularly, the present invention relates to new phenoxyalkylamine derivatives of the formula (1) wherein R1 and R2, independently from each other, mean hydrogen, halogen or C1-4 alkyl group; R3, R4 and R5, independently from each other, stand for hydrogen or C1-4 alkyl group; R6 represents hydrogen, C1-4 alkyl or benzyl group; R7 means nitro group or amino group optionally monosubstituted by C1-4 alkyl, benzoyl, C1-4 alkylcarbonyl, C1-4 alkylsulfonyl, C1-4 alkylcarbamoyl or C1-4 alkylthiocarbamoyl group; both n and m are 0 or 1, with the proviso that R2 is different from hydrogen, when R1 is hydrogen, as well as stereoisomers or mixtures of stereoisomers thereof, acid addition salts thereof and hydrates, prodrugs and metabolites of all these compounds.

Abstract: The invention relates to R-2-[3-([1,4]benzodioxan-2-ylmethylamino)-1-propyl]-3(2H)-pyridazinone of formula (1), and to S-2-[3-([1,4]benzodioxan-2-ylmethylamino)-1-propyl]-3(2H)-pyridazinone of formula (2), and to acid-addition salts thereof as well as pharmaceutical compositions containing these compounds. Furthermore, the invention relates to a process for the preparation of the above compounds. The new starting compounds of formulae (4) and (5) are also involved in the scope of the invention. The compounds according to the invention possess &agr;1- and &agr;2-adrenoceptor antagonistic effects and urogenital selectivity. Thus, they are useful for the treatment of the benign prostate hyperplasia.
