[ogsa-hpcp-wg] Minutes for OGSA HPC Profile telecon (Aug 18 2006)

[Subramaniam, Ravi]

Hi,

In line with Marvin's comments, I think we had this discussion on vector
versus singleton at the last F2F. We decided that HPC would have to
address both aspects but approach the elemental case first and other
situations would be done as extensions. Right? (I am sure we had this
discussion since I remember distinctly raising the notion that singleton
could also be a "vector of length 0". No doubt, a simple observation.
But with implications in the architecture/profile. This led to the
discussion (not resolved) as to what is elemental as per Marvin's
summary below)

Hi;

I totally agree that they're important.  However, in keeping with having
as simple an HPC Profile base case as possible, the HPC Profile will
restrict its base case to only allowing singleton vectors.  Whether we
want to define the BES base case as non-vector operations and then
immediately define a vector extension or whether we want to define the
base case as vector operations with the restriction being put in the HPC
Profile specification is something still to be determined.

Marvin.

I am also concerned about this. We've never had vector operations in
Globus, but Chris Smith argued eloquently for their importance in the
early stages of BES, and so I became convinced that we need them.

Could you expand on this... having the BES interface support operations
on vectors of activities has been fairly important. Is this is what you
are planning to remove?

Is this a profile restriction or an edit on the main BES document?
