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 at http://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 program agenda,
