Hello everyone
I started to implement the tool GT 5.0.3 and also to write about it.
Except that I have encountered some questions that could not only
solve with the site information from Globus.
The first issue is related to which language is built exactly GT5.0.3
(C, Java?).
It is written in C, some part in Perl, shell. I hope I did not miss
anything.
The second question is how is the discovery of services in the Globus
ambience 5.0.3. Existed in the GT4 documentation Web Services and
Information Services, of how everything worked, not in GT5.
In October, 2009, Ian Foster described future plans for Globus Toolkit
in the email
http://lists.globus.org/pipermail/gt-user/2009-October/008578.html. One
paragraph says about information services:
2.d. While MDS is applicable to a broad range of monitoring and
discovery tasks, in practice its predominant use has been to build
service registries/catalogs for TeraGrid, caBIG, and BIRN, with
limited adoption for systems monitoring in a few other communities.
Since MDS4 is intimately intertwined with GT4 Java Core, it would
require a substantial reimplementation effort to update it to Crux.
Meanwhile, the state of monitoring tools has evolved considerably
since MDS4 was first conceived, with the widespread adoption of highly
capable, open source monitoring tools such as Nagios. Therefore we
have begun work on a more focused effort to design and implement next
generation service registry capabilities using Crux, which we are
calling our Integrated Information Services (IIS) effort. This IIS
effort is still in the requirements gathering phase, with no releases
planned until sometime in 2010. We recommend that monitoring needs be
met using other tools such as Nagios.
IIS is currently being tested and as far as I know should be released
this year and implemented in several grid projects. By that time MDS
from GT4.0.8 is used in many project.
