    Optimal Loop Parallelization under Register Constraints

    This report deals with the interaction between instruction scheduling and register allocation, in the case of straight line code and in the case of loops. This problem is at the heart of code optimization in microprocessors with instruction-level parallelism. Usual solutions use heuristics based on a decoupled approach. We propose here a formulation by linear integer programming, that allows dependence, resource and register constraints to be integrated in the same framework. By varying the parameters, all kinds of optimization problems can be solved exactly (maximization of the throughput, minimization of the number of registers). We report on examples of computation timings that turn out to be prohibitive in some specific cases, but tractable on average

    AbstractFollowing the cooperation agreement in the field of medicine and health between the government of the French Republic and the government of the People's Republic of China, a « Franco-chinese Herbal Group » has been set up.The objective of this group is to establish a list of medicinal plants from the traditional Chinese Pharmacopoeia, which could be proposed to the French Health Products Agency with a view to include them eventually in the French Pharmacopoeia and in the Agency's list of plants (Instructions Booklet N° 3).The group is made up of pharmacological, galenical, toxicological and clinical experts from both parties. It officially meets twice a year. Plants proposed must comply with quality and safety criteria required for herbal medicinal products in France. Traditionnal usage must be acknowledged.The development of herbal medicinal products is difficult in Europe because differents reglementary rules exist in the differents european member states. The basis of harmonisation should be established on the assessment of quality objectives and using safety and efficacy data already available. Don't give a legal status to herbal medicine provide abuses and accidents
