We have at least two countries Cuba and Bolivia, with a very poor network and Cuba's it is not
even know. Both countries demonstrate that there are physicists available to participate in the
Experiments of LHC. Bolivia even has a long tradition working with Cosmic Rays Physics.
We observe that there are six countries with 10 Mbps, among them Colombia is participating in
the CMS collaboration and also in ATLAS. They are trying to build a cluster to participate in the
GRID and even to be eventually a T3 of the system, connected to the T2-HEPGRID-Brazil-
UERJ. If this is not upgraded soon, this dream will not be fulfilled because of the connectivity.
There are two countries with 45 Mbps, Peru and Panama. Peru already has physicists
participating in LHC experiments. And Uruguay has 34 Mbps.
Three countries are in better conditions, Argentina, Chile and Venezuela with 90 Mbps but not
enough to be part of the GRID system. They certainly have to upgrade their connectivity soon to
be possible to participate in the GRID of LHC experiments.
Finally, only Brazil and Mexico have the possibility to be part of the GRID system of LHC. In
Mexico we have 1 Gbps available now and in Brazil 2.5 Gbps, waiting for an upgrade in 2008 for
10 Gbps.
This scenario allows us to conclude that the main bottleneck for the development networks and
GRID in Latin America is the poor connectivity inside of RedCLARA. This has to be the main
concern of L.A. community for the near future experiments.
We have to say that this is the case for science. Soon, other areas will also need to have strong
communication with their partners to work in international collaboration.
HEPGRID-Brazil-UERJ:
As we said, in Latin America Brazil tiers 2 has participated in the GRID system of CMS in all
types of characteristics of the GRID process. But at same time those clusters were built, a number
of network projects were done inside the country to make communication possible among
clusters. This was possible due to the effort of RNP to increase internal and external connectivity.
It was necessary to start an upgrading process also of institution networks. It means that short,
long and last mile connections have been upgraded. Many of these projects made by NRENS
National Research and Education Networks - have been very successful and are not finished. It is
a process of continued upgrading of several parts of the global networks. Examples of these
developments are the project of RNP, ANSP, REDERIO, and other state/regional networks. In
our view, the most important project at national level is the RECOMEP- Metropolitan Networks
for Research and Educations - http://www.redecomep.rnp.br/ , with rings of 1 Gbps connected to
the backbone of RNP, of 10 Gbps.
In Brazil there are two Tier2 (SPRACE in S.Paulo http://www.sprace.org.br/SPRACE/ and
HEPGRID-Brazil-UERJ http://www.hepgrid.uerj.br/ ) of the system of the CMS/GRID and
partners of the USA-Tiers2-CMS.
The Tier 2 HEPGRID-Brazil-UERJ has been upgraded and we expect a new and substantial
upgrade for next year. The general connectivity is shown in the Figure 30 below.
