The Parallel Multithreaded Machine (PM2) is a software for parallel networking of computers.
PM2 is an open-source distributed multithreaded programming environment designed to support efficiently distributed programs with a highly irregular behavior (e.g. branch and bound search, computation on sparse matrices, etc.) on distributed architectures. It is distributed under the GPL.
PM2 adheres to the SPMD (Single Program Multiple Data) programming model, in a way very similar to the PVM and MPI communication libraries. The user writes a single program text, a copy of which is launched by a specific load command on each processing node of the current configuration. It is up to the programmer to include branching so as to differentiate between the processing nodes. This way it allows a network of heterogeneous machines to be used as a single distributed parallel processor.
It is primarily designed for medium-size clusters of commodity processing nodes interconnected by high-performance networks, but nothing prevents the use on massively parallel MIMD machines at one end of the spectrum, or as a support for metacomputing over the Internet on the other end. It supports heterogeneous networking configurations, such as sets of interconnected clusters.
Toda dientes, tu sonrisa
francamente contagiosa
desde un poster de papel
pegado en la pared, mama
Las amigas, envidiaban
esa falsa risa facil
que aparentan desde la pantalla, sin querer
las divas como tu, mama
Y yo que siempre te esperaba
para hablarte de mis cosas
terminaba por dormir
sin que llegaras
Volabas cada vez mas alto
casi como los cometas
yo aqui abajo
extrañando tu presencia
Bye mama, me voy adios
a segir mis propias reglas del juego
mientras quede un atomode sendero
por delante caminare
Bye mama, adios me voy
con el cielo transparente por techo
mientras note que esta vivo mi cuerpo
sin cadenas caminare
Ya comprendo
que tampoco lo tenias nada facil
convertirte en padre y madre sin desfallecer
tan valiente tu
Y yo que te necesitaba
mas que madre confidente
para ver de compartir
sueños y dudas
Te esperaba y no llegabas
si venias habia gente
y yo sola no me pidas que me quede
como quieres que me quede
