November 15th, 2010

New Orleans, Louisiana, USA

Co-located with with IEEE/ACM International Conference for

High Performance Computing, Networking, Storage and Analysis (SC10)

The 3rd 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 large-scale many-task computing (MTC) applications on large scale

clusters, Grids, Supercomputers, and Cloud Computing infrastructure. 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 raw hardware, parallel file system contention

and scalability, data management, I/O management, 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 (pending approval). The workshop

will be co-located with the IEEE/ACM Supercomputing 2010 Conference in New Orleans

Louisiana on November 15th, 2010. For more information, please see

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 now online (e.g. TACC Sun Constellation System - Ranger), Grids (e.g. TeraGrid)

with a dozen sites and 100K+ processors, and supercomputers with 150K~200K processors

(e.g. IBM BlueGene/P, Cray XT5); furthermore, new supercomputers are scheduled to come

online with 300K processor-cores and more than 1M threads (e.g. IBM Blue Waters). 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, commonly known to fit in the

high-throughput computing (HTC) paradigm.

Many-task computing (MTC) aims to bridge the gap between two computing paradigms, HTC and

HPC. MTC is reminiscent to HTC, but it differs in the emphasis of using many computing

resources over short periods of time to accomplish many computational tasks (i.e. including

both dependent and independent tasks), where the primary metrics are measured in seconds

(e.g. FLOPS, tasks/s, MB/s I/O rates), as opposed to operations (e.g. jobs) per month. MTC

denotes high-performance computations comprising multiple distinct activities, coupled via

file system operations. Tasks may be small or large, uniprocessor or multiprocessor,

compute-intensive or data-intensive. The set of tasks may be static or dynamic, homogeneous

or heterogeneous, loosely coupled or tightly coupled. The aggregate number of tasks,

quantity of computing, and volumes of data may be extremely large. MTC includes loosely

coupled applications that are generally communication-intensive but not naturally expressed

using standard message passing interface commonly found in HPC, drawing attention to the

many computations that are heterogeneous but not "happily" parallel.

There is more to HPC than tightly coupled MPI, and more to HTC than embarrassingly parallel

long running jobs. Like HPC applications, and science itself, applications are becoming

increasingly complex opening new doors for many opportunities to apply HPC in new ways if

we broaden our perspective. Some applications have just so many simple tasks that managing

them is hard. Applications that operate on or produce large amounts of data need

sophisticated data management in order to scale. There exist applications that involve many

tasks, each composed of tightly coupled MPI tasks. Loosely coupled applications often have

dependencies among tasks, and typically use files for inter-process communication. Efficient

support for these sorts of applications on existing large scale systems will involve

substantial technical challenges and will have big impact on science.

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,

parallel file system contention and scalability, data management, I/O management, 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.

http://dsl.cs.uchicago.edu/MTAGS09/; for the initial workshop we ran in 2008, please see

http://dsl.cs.uchicago.edu/MTAGS08/. We also ran a special issue on Many-Task Computing in the

IEEE Transactions on Parallel and Distributed Systems (TPDS) which will appear in November 2010,

which can be found at http://dsl.cs.uchicago.edu/TPDS_MTC/. We, the workshop organizers, 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.
