The 2nd ACM Workshop on Many-Task Computing on Grids and Supercomputers
(MTAGS) 2009
http://dsl.cs.uchicago.edu/MTAGS09/
---------------------------------------------------------------------------------------
November 16th, 2009
Portland, Oregon, USA
Co-located with with IEEE/ACM International Conference for
High Performance Computing, Networking, Storage and Analysis (SC09)
=======================================================================================
The 2nd workshop on Many-Task Computing on Grids and Supercomputers
(MTAGS) will
provide the scientific community a dedicated forum for presenting new
research,
development, and deployment efforts of loosely coupled large scale
applications on
large scale clusters, Grids, Supercomputers, and Cloud Computing
infrastructure.
Many-task computing (MTC), the theme of the workshop encompasses loosely
coupled
applications, which are generally composed of many tasks (both
independent and
dependent tasks) to achieve some larger application goal. This workshop
will cover
challenges that can hamper efficiency and utilization in running
applications on
large-scale systems, such as local resource manager scalability and
granularity,
efficient utilization of the raw hardware, parallel file system
contention and
scalability, reliability at scale, and application scalability. We
welcome paper
submissions on all topics related to MTC on large scale systems. Papers
will be
peer-reviewed, and accepted papers will be published in the workshop
proceedings as
part of the ACM digital library. The workshop will be co-located with the
IEEE/ACM Supercomputing 2009 Conference in Portland Oregon on November
16th, 2009.

Scope
---------------------------------------------------------------------------------------
This workshop will focus on the ability to manage and execute large
scale applications
on today's largest clusters, Grids, and Supercomputers. Clusters with
50K+ processor
cores are beginning to come online (i.e. TACC Sun Constellation System -
Ranger), Grids
(i.e. TeraGrid) with a dozen sites and 100K+ processors, and
supercomputers with 160K
processors (i.e. IBM BlueGene/P). Large clusters and supercomputers have
traditionally
been high performance computing (HPC) systems, as they are efficient at
executing
tightly coupled parallel jobs within a particular machine with low-latency
interconnects; the applications typically use message passing interface
(MPI) to
achieve the needed inter-process communication. On the other hand, Grids
have been the
preferred platform for more loosely coupled applications that tend to be
managed and
executed through workflow systems. In contrast to HPC (tightly coupled
applications),
these loosely coupled applications make up a new class of applications
as what we call
Many-Task Computing (MTC). MTC systems generally involve the execution
of independent,
sequential jobs that can be individually scheduled on many different
computing
resources across multiple administrative boundaries. MTC systems
typically achieve this
using various grid computing technologies and techniques, and often
times use files to
achieve the inter-process communication as alternative communication
mechanisms than
MPI. MTC is reminiscent to High Throughput Computing (HTC); however, MTC
differs from
HTC in the emphasis of using many computing resources over short periods
of time to
accomplish many computational tasks, where the primary metrics are
measured in seconds
(e.g. FLOPS, tasks/sec, MB/s I/O rates). HTC on the other hand requires
large amounts
of computing for longer times (months and years, rather than hours and
days, and are
generally measured in operations per month).
Today's existing HPC systems are a viable platform to host MTC
applications. However,
some challenges arise in large scale applications when run on large
scale systems,
which can hamper the efficiency and utilization of these large scale
systems. These
challenges vary from local resource manager scalability and granularity,
efficient
utilization of the raw hardware, shared file system contention and
scalability,
reliability at scale, application scalability, and understanding the
limitations of the
HPC systems in order to identify good candidate MTC applications.
Furthermore, the MTC
paradigm can be naturally applied to the emerging Cloud Computing
paradigm due to its
loosely coupled nature, which is being adopted by industry as the next
wave of
technological advancement to reduce operational costs while improving
efficiencies in
large scale infrastructures.
For an interesting discussion in a blog by Ian Foster on the difference
between MTC and
HTC, please see his blog
athttp://ianfoster.typepad.com/blog/2008/07/many-tasks-comp.html.
We also published two papers that are highly relevant to this workshop.
One paper is
titled "Toward Loosely Coupled Programming on Petascale Systems", and
was published in
SC08; the second paper is titled "Many-Task Computing for Grids and
Supercomputers",
which was published in MTAGS08. Furthermore, to see last year's workshop
