The use and development of High Performance Computing in Latin America is steadily growing. New challenges come from the capabilities provided by clusters, grids, and distributed systems for HPC, promoting research and innovation in this area.

Building on the great success of the previous four editions, this year the Latin American Symposium on High Performance Computing is growing to include three major events: the High Performance Computing School (ECAR 2012), the V HPCLatAm2012 International Symposium itself (both to be held in Buenos Aires, from July 23 to August 3), and the HPC Day (August 30) within the 41st Argentine Conference of Informatics (41 JAIIO).

The main goal of HPCLatAM2012 is to provide a regional forum fostering the growth of the HPC community in Latin America through the exchange and dissemination of new ideas, techniques, and research in HPC. The symposium will feature invited talks from academy and industry, short- and full-paper sessions presenting both mature work and new ideas in research and industrial applications. Suggested topics of interest include, but are not restricted to:

Parallel Algorithms and Architectures Distributed and Grid Computing Cloud Computing High Performance Applications High Performance Software Tools Visualization and Data Management

Tools and Environments for High Performance System Engineering Component Technologies for High Performance Computing Parallelism and Data Sharing on Multi-core Architectures Virtualization in High Performance Computing Graphics Processing Units in High Performance Computing Country-wide Grid Initiatives

INSTRUCTIONS FOR AUTHORS
Short- and full-length papers must be written in English according to Springer LNCS style (guidelines available at: http://www.springer.de/comp/lncs/authors.html). Papers must not have been previously published or submitted elsewhere. Submissions will be handled electronically using Easy chair system, please follow the link to submit.

The authors of accepted papers must guarantee that their paper will be presented at the symposium. At least one author of each accepted paper must be duly registered for the symposium in order for the paper to be scheduled in the papers session and to appear in the V HPCLatAm2012 proceedings.

Full papers must not exceed 16 pages, including name, affiliation and address of the author(s), figures, tables, references, and an abstract of no more than 200 words. All full paper submissions will be carefully reviewed by at least two experts and returned to the author(s) with comments to ensure the high quality of accepted papers. Full papers accepted for the program will appear in the V HPCLatAm2012 proceedings.

Authors are invited to submit short papers (extended abstracts) for results that are too late to be submitted as regular full-length papers. Short papers must not exceed 4 pages. Short papers accepted for the program will appear in the proceedings (not expanded to full papers, and with Extended Abstract in the title) and be presented orally during the symposium (in suitably shorter speaking slots) as a regular part of the program.

Authors of the best papers submitted to the workshop will be invited to submit their extended versions to Cluster Computing: Special Issue on Soft Computing Techniques in Cluster and Grid Computing Systems. Cluster Computing, The Journal of Networks, Software Tools and Applications (2010 Impact Factor: 0.679) is indexed on SCI, SCOPUS, INSPEC, Google Scholar, EBSCO, CSA, ACM Digital Library, CSI, DBLP, JCR/SE, and others.
