(Named after Gene Amdahl) If F is the fraction ofa calculation that is sequential, and (1-F) is the fractionthat can be parallelised, then the maximum speedup that canbe achieved by using P processors is 1/ (F+ (1-F)/P).[Gene Amdahl, "Validity of the Single Processor Approach toAchieving Large-Scale Computing Capabilities", AFIPSConference Proceedings, (30), pp. 483-485, 1967].

Proto Oncogene Proteins c erbB 2
- cell surface protein-tyrosine kinase that is found to be overexpressed in significant number adenocarcinomas. It has extensive homology can heterodimerize EGF EPIDERMAL GROWTH FACTOR), 3 receptor (RECEPTOR, 3) and the 4 receptor. Activation of erbB-2 receptor occurs during heterodimer formation with a ligand-bound erbB family members. EC 2.7.11.-.
