Alinhamento de seqüências biológicas em arquiteturas com memória distribuída

Abstract

The use of cluster of computers for solving problems that require a great quantity

of computational resources is becoming an interesting alternative. Clusters are economically

feasible and of easy maintenance, offering a computational power equivalent to that

of supercomputers. However developing applications for this kind of architecture is complex because it involves issues that are not present in the sequential programming such

as data communication and concurrent tasks synchronization, problems that usually are

handled by specialized software packages in supercomputers. Considering this context,

this work presents the development of a mechanism for supporting communication on clusters of computers focused on exploring this hardware platform for high performance processing. The mechanism was created as a library of functions written in C and it is based on the Active Messages model. Its implementation was performed on the applicative level, using light multiprogramming techniques as programming resou
