Description
The paper reflects on the experience gained from the
deployment of the gLite
middleware on the EGEE infrastructure and describes the
changes required to meet the
demanding requirements over the next few years. In
particular, focus is given to the
the changes required in YAIM, the grid middleware
configuration, to addresses the
required granularity of releases, the changes that are
necessary for a modular
approach and how a smooth transition between can be
achieved. In addition, most
computing centers are upgrading hardware from 32 bit CPUs to
64 bit. The additional
problems this creates is discussed along with the possible
solutions so that full
support can be given and the resulting affect on YAIM and
grid middleware in general
is described. An additional requirement is the need to
support multiple platforms and
migrating to newer versions of the OS. The middleware
evolution also contains similar
transitions such as upgrading VDT, which is at the core of
the middleware. This paper
contains information that will be of use to system
administers of computing centers
who run grid services.
