Unified Parallel C （UPC） is a parallel extension of ANSI C based on the Partitioned Global Address Space （PGAS） programming model, which provides a shared memory view that simplifies code development while it can take advantage of the scalability of distributed memory architectures. Therefore, UPC allows programmers to write parallel applications on hybrid shared/distributed memory architectures, such as multi-core clusters, in a more productive way, accessing remote memory by means of different high-level language constructs, such as assignments to shared variables or collective primitives. However, the standard UPC collectives library includes a reduced set of eight basic primitives with quite limited functionality. This work presents the design and implementation of extended UPC collective functions that overcome the limitations of the standard collectives library, allowing, for example, the use of a specific source and destination thread or defining the amount of data transferred by each particular thread. This library fulfills the demands made by the UPC developers community and implements portable algorithms, independent of the specific UPC compiler/runtime being used. The use of a representative set of these extended collectives has been evaluated using two applications and four kernels as case studies. The results obtained confirm the suitability of the new library to provide easier programming without trading off performance, thus achieving high productivity in parallel programming to harness the performance of hybrid shared/distributed memory architectures in high performance computing.

Preparation of monospecific anti-PAG antibodies for cattle pregnancy detection: use of synthetic peptides to improve specificity

引用

Advances in Bioscience and Biotechnology 2011年第2期2卷 85-88页

作者： Jimena Inés Ruiz álvarez Juan Manuel teijeiro Patricia Estela Marini Instituto de Biología Molecular y Celular de Rosario IBR-CONICET and Facultad de Ciencias Bioquímicas y Farmacéuticas Universidad Nacional de Rosario

Immunological methods involving pregnancy associ-ated glycoproteins (PAG) are used for cattle preg-nancy detection. The faults of these methods could be overcomed by using antibodies specific for each member of the PAG family. In order to differentiate between very similar proteins, preparation of anti-bodies specific for peptides is a method of choice. In this work, we summarize a series of considerations regarding peptide design and choose free access NCBI, Antigenicity Plot, EMBOSS Antigenic and Expasy tools to apply them. We design peptides spe-cific for different reported PAG members and obtain the corresponding polyclonal antibodies for five of them.
