Overview GigaPort Research: Tools and Results
This page gives an overview of the tools and results from which the research is
supported by the
GigaPort project. Please note that some of
these tools and results were already related with the tasks defined in
Work Package 3 from the
DataTAG project which has been
finished now. Please note also that not all work done can be published here. The
following Web sites are available:
Network Test and Monitoring Tools.
In this site an overview has been given of the proposed test and monitor
tools to be used. Also short description of these tools have been given.
Useful, non-default configurations are discussed and modifications and
extensions of the discussed tools are available for downloading.
Netherlight Lambda Test Results.
In this site the monitor and test results are presented that were obtained
Netherlight Lambda from
SURFnet. Because both networks have
about the same characteristics (long fat networks with limited routing and
therefore relatively few memory buffer capacity, these results may serve
very well as a testbed for the
DataTAG connection from
which some test results are also presented in the
DataTAG CERN - StarLight Link Test Results.
In this site the test results are presented that were obtained at the
DataTAG test link between
CERN, Geneva and
Protocol Testbed Results.
In this site the results are presented from experiments with alternative
test protocols such as UDT and
RBUDP, also in combination
with the standard TCP and UDP protocols. These tests were and still are
being executed as a function of the round-trip time to investigate the
influences of that parameter.
GridFTP Tests on DAS-2 Cluster.
The purpose of this monitor which was run on the
DAS-2 cluster was to get
experience with the network measurements and tests in a Grid way. During the
test periods various job scheduling techniques were used. The monitor was
stopped at the moment some
DAS-2 clusters were no longer
In these tests some network components of the
For these tests our Rembrandt hosts were used which were during the tests
equipped with various 10 Gbit/s Ethernet interfaces.
DAS-3 Myrinet Tests.
In this site the results of tests are presented that were run upon the
Myri-10G network technology that is used
at the DAS-3 computer clusters. New
results will still being add to this site.
