THE AUSTRALIAN NATIONAL UNIVERSITY
POLICY OF THE SUPERCOMPUTER TIME ALLOCATION COMMITTEE
The criteria for resource allocation used by the Supercomputer Time
Allocation Committee are:
- Academic quality, as assessed by referees using as guidelines:
- the originality of the proposed work;
- the potential of the work to generate new knowledge in an important area;
- the comparative scientific merits of the work within its discipline;
- the experience and demonstrated research capacity of the applicant;
- the reasonableness of the requested resource allocation.
-
The track record of efficient usage and achievement in the case of
continuing grants.
The Committee aims to encourage new and innovative projects,
particularly those in areas not traditionally involving large-scale
computations.
Large requests
Local, national and international referees may be contacted, particularly for
proposals making large requests. Investigators may nominate referees.
These referees may or may not be contacted at the Chairman's discretion.
Investigators may, however, nominate referees that the Chairman should not
contact. Continuing projects may be refereed at intervals at the discretion of
the Chairman.
Policy for new large projects:
When considering a new large project in the
absence of a relevant track-record, the Committee generally makes a provisional
smaller grant and releases the balance of the grant when the investigator can
show evidence of reasonable progress.
The committee, whose Chairman is nominated by the Vice-Chancellor, is currently
composed as follows:
Professor Denis Evans (Chairman)
Professor M A Bennett (RSC)
Dr G Davies (RSES)
Dr S Marcelja (RSPhySE)
Dr B P Molinari (FEIT)
LARGE USERS - PLEASE NOTE:
If you were deemed a 'large user' in the last period, there are
restrictions on the size of the grant you can request.
Policy for 'large users'
For some time the STAC has been concerned that the size of the requests by
users of large amounts of time has become unrealistic compared with the
resources available and the grants actually made. These unrealistic requests
have two deleterious effects. First, referees are presented with apparently
excessive requests which does not reflect well on the individuals concerned or
on the University. Second, it is unfair to users who submit realistic
requests.
A new policy was introduced successfully in 1993 to ameliorate this problem.
In essence, unless extraordinary reasons are given, the committee will only
entertain modest increases beyond the previous allocation actually
granted for continuing projects that are classified as 'large'. (See
below, for the definition of 'large'.)
While this apparently introduces a conservative bias into the allocation
process, given the mature nature of the user base, the STAC does not believe
that this is an overwhelming objection. New projects, including 'large' ones,
and the growth of existing projects into 'large' projects will continue to be
encouraged. New 'large projects' will continue to be handled as per the
existing policy outlined overleaf.
The existing policy for handling demand in excess of supply will continue to be
followed and hence grants to new 'large projects' will largely be at the
expense of existing 'large users'. If the general level of demand falls, or
the application of Criteria outlined above becomes more favourable, the
grants allocated to continuing large projects will be increased.
Implementation:
When grants are invited, we will:
- notify Principal Investigators if their existing projects are classified
as 'large'.
- inform each PI of their previous grant for each of their projects.
In the absence of a special written submission such Principal Investigators
should then ensure that:
- for any single project, the request is for no more than the previous grant.
- the aggregate request over all their projects classified as belonging to a
single 'large' project group, should be no greater than their previous total
allocation.
The STAC understands that there will be occasions when 'large' users have good
reason to exceed the above limits, particularly if their usage undergoes
periodic variations. Such circumstances should be explained in the separate
written submission.
PROCEDURE USED WHEN TOTAL REQUESTS EXCEED RESOURCES AVAILABLE:
These details are provided for those interested and generally affect only
'large users'.
The total requests for resources, even after the above procedures have been
followed, have been up to twice the time available. This excess request arises
largely from a small number of large projects. The STAC has developed the
following mechanism to handle this:
- For all projects except 'large projects' (see below), grants are made by
applying discount factors based on the criteria described above to the request
for service units made by the applicant.
- Projects, or groups of projects with related investigators, which request a
large number of service units are identified as 'large project-suites'. The
number of service units corresponding to 'large' is at the discretion of the
Committee and it is considered wise not to publish this figure. The procedure
for allocating resources to 'large project' ensures that there is no
discontinuity in allocations between proposals that are deemed to be 'small' or
'large'.
- For new projects falling within the category of a 'large project-suite',
the number of service units requested by the applicant
will be discounted on the basis of criteria 1, 2 and 3 above and
combined with the continuing 'large project-suites' for establishing
the final allocation of resources.
- For continuing projects that are part of 'large project-suites', applicants
are required to follow the new policy detailed below when specifying the number
of service units requested for such projects.
- 'Large project-suites' share in the balance of resources left after
satisfying all other applications. Each such suite is first granted, free of
an additional 'large user' discount, the maximum 'small project' allocation .
This 'large user' discount is applied to the balance of the suite's total
notional grant after step C and is proportional to the remaining resources
available divided by the remaining total of notional grants summed over all
'large project-suites'. Finally, grants are made to individual projects in
each suite.
