    Notizen: Abstract We present an efficient parallelization strategy for speeding up the computation of a high-accuracy 3-dimensional serial Navier-Stokes solver that treats turbulent transonic high-Reynolds flows. The code solves the full compressible Navier-Stokes equations and is applicable to realistic large size aerodynamic configurations and as such requires huge computational resources in terms of computer memory and execution time. The solver can resolve the flow properly on relatively coarse grids. Since the serial code contains a complex infrastructure typical for industrial code (which ensures its flexibility and applicability to complex configurations), then the parallelization task is not straightforward. We get scalable implementation on massively parallel machines by maintaining efficiency at a fixed value by simultaneously increasing the number of processors and the size of the problem. The 3-D Navier-Stokes solver was implemented on three MIMD message-passing multiprocessors (a 64-processors IBM SP2, a 20-processors MOSIX, and a 64-processors Origin 2000). The same code written with PVM and MPI software packages was executed on all the above distinct computational platforms. The examples in the paper demonstrate that we can achieve efficiency of about 60% for as many as 64 processors on Origin 2000 on a full-size 3-D aerodynamic problem which is solved on realistic computational grids.

    Notizen: Abstract  We describe here the first full-length sequence of a member of a novel gene family encoding a protein in the mouse that we call Lupin. Lupin is homologous to a human protein previously called p36, which was purified from α-interferon-treated cells that formed lupus inclusions. Lupus inclusions are dense intracellular deposits found in endothelial cells and lymphocytes of patients with systemic lupus erythematosis and AIDS. Proteins closely related to Lupin exist in evolutionarily divergent species including Caenorhabditis elegans, Drosophila and zebrafish. At least one other lupin-related gene is expressed in the mouse and in man. Lupin is expressed in mouse embryos and adults, notably in liver, spleen, central nervous system, multiple epithelia and all types of muscle. In skeletal muscle, expression analysis suggests that Lupin associates with the contractile apparatus.
