Message from the Program Chairs

 

This proceeding gathers information about the participants of the Workshop on Clusters, Clouds, and Data for Scientific Computing that will be held at La Maison des Contes, 427 Chemin de ChanzŽ, France on September 11th – 14th, 2012.  This workshop is a continuation of a series of workshops started in 1992 entitled Workshop on Environments and Tools for Parallel Scientific Computing. These workshops have been held every two years and alternate between the U.S. and France. The purpose of this the workshop, which is by invitation only, is to evaluate the state-of-the-art and future trends for cluster computing and the use of computational clouds for scientific computing.

This workshop addresses a number of themes for developing and using both cluster and computational clouds. In particular, the talks covered:

¤  Survey and analyze the key deployment, operational and usage issues for clusters, clouds and grids, especially focusing on discontinuities produced by multicore and hybrid architectures, data intensive science, and the increasing need for wide area/local area interaction.

¤  Document the current state-of-the-art in each of these areas, identifying interesting questions and limitations. Experiences with clusters, clouds and grids relative to their science research communities and science domains that are benefitting from the technology.

¤  Explore interoperability among disparate clouds as well as interoperability between various clouds and grids and the impact on the domain sciences.

¤  Explore directions for future research and development against the background of disruptive trends and technologies and the recognized gaps in the current state-of-the-art.

 

Speakers will present their research and interact with all the participants on the future software technologies that will provide for easier use of parallel computers. 

 

This workshop was made possible thanks to sponsorship from NSF, AMD, ANR, Aristote, Bull, CEA, Cray, Google, France Grilles, Hewlett-Packard, Microsoft Research, The Portland Group, with the scientific support of the Innovative Computing Laboratory at the University of Tennessee in Knoxville (UTK) and University Joseph Fourier of Grenoble.

Arrival / Departure Information:

 

Here is some information on the meeting in Lyon.  We have updated the workshop webpage http://bit.ly/ccdsc2012 with the workshop agenda.

 

On Tuesday September 11th there will be a bus to pick up participants at Lyon's Saint ExupŽry (old name Satolas) Airport at 3:00. (Note that the Saint ExupŽry airport has its own train station with direct TGV connections to Paris via Charles de Gaulle. If you arrive by train at Saint ExupŽry airport please go to the airport meeting point (point-rencontre) (second floor, next to the shuttles, near the hallway between the two terminals, see http://www.lyon.aeroport.fr/en/maps/halls.htm#).

 

The bus will then travel to pick up people at the Lyon Part Dieu railway station at 4:45. (There are two train stations in Lyon, you want Part Dieu station not the Perrache station.) There will be someone with a sign at the "Meeting Point/point de rencontre" of the station to direct you to the bus.

 

The bus is expected to arrive at the La Maison des Contes around 5:30. We would like to hold the first session on Tuesday evening from 6:30 pm to 8:00 pm, with dinner following the session. The La Maison des Contes is about 43 Km from Lyon. For a map to the La Maison des Contes go to http://maps.google.com and type in: Ò427 chemin de ChanzŽ 69490 DareizŽÓ or see: Maps: http://www.cs.utk.edu/~dongarra/CCDSC-2012/maps.pdf

Map of Chateau: http://www.cs.utk.edu/~dongarra/CCDSC-2012/chateau.pdf

 

VERY IMPORTANT: Please send your arrival and departure times to Jack so we can arrange the appropriate size bus for transportation.  VERY VERY IMPORTANT: If your flight is such that you will miss the bus on Tuesday, September 11th at 3:00 send Bernard your flight arrival information so he can arrange for a transportation to pick you up at the train station or the airport in Lyon. It turns out that a taxi from Lyon to the Chateau can cost as much as 100 Euro and the Chateau may be hard to find at night if you rent a car and are not a French driver :-). 

 

At the end of the meeting on Friday afternoon, we will arrange for a bus to transport people to the train station and airport. If you are catching an early flight in the morning of Saturday, September 15th you may want to stay at the hotel located at Lyon's Saint ExupŽry Airport,

see http://www.lyon.aeroport.fr/eng/en/services/index.htm for details.

There are also many hotels in Lyon area, see: http://www.lyon-france.com/

 

Due to room constraints at the La Maison des Contes, you may have to share a room with another participant. Dress at the workshop is informal.  Please tell us if you need special requirements (vegetarian food etc...) We are expecting to have internet and wireless connections at the meeting.

 

Please send this information to Jack (dongarra@eecs.utk.edu) by July18th.

Title:

Assertion Based Parallel Debugging: A new way of thinking?

Abstract:

Programming languages have advanced tremendously over the years, but program debuggers have hardly changed. Sequential debuggers do little more than allow a user to control the flow of a program and examine its state. Parallel ones support the same operations on multiple processes, and are adequate with a small number of cores, but become unwieldy and ineffective on very large machines. Typical scientific codes have enormous multi-dimensional data structures and it is impractical to expect a user to view the data using traditional display techniques.

 

In this talk I will discuss the use of debug-time assertions (both within and across programs), and show that these can be used to debug parallel programs. The techniques reduce the debugging complexity because they reason about the state of large arrays without requiring the user to know the expected value of every element. When used across programs, the technique can help find errors that occur when a program is ported to a new platform. Whilst assertions can be expensive to evaluate, their performance can be improved by running them in parallel. We have implemented these ideas in a new debugger called Guard, and will illustrate its performance  on tens of thousands of cores on a Cray XE6.

Title:

Energy-aware mappings of series-parallel workflows onto chip multiprocessors

 

Abstract:

We discuss the problem of mapping streaming applications that can be modeled by a series-parallel graph onto a 2-dimensional tiled CMP architecture. The objective of the mapping is to minimize the energy consumption, using dynamic voltage scaling techniques, while maintaining a given level of performance, reflected by the rate of processing the data streams. This mapping problem turns out to be NP-hard, but we identify a simpler instance, whose optimal solution can be computed by a dynamic programming algorithm in polynomial time. Several heuristics are proposed to tackle the general problem, building upon the theoretical results. Finally, we assess the performance of the heuristics through a set of comprehensive simulations.

Title:

Task Farming in Cloud Environments under Budget Constraints

 

Abstract:

Elastic applications like bags of tasks can greatly benefit from Infrastructure as a Service (IaaS) clouds that let users allocate compute resources on demand, charging based on reserved time intervals. Users, however, still need guidance for mapping their applications onto multiple IaaS offerings, both minimizing execution time and respecting budget limitations.  For budget-controlled execution of bags of tasks, we have developed our BaTS scheduler. BaTS estimates possible budget and makespan combinations using a tiny task sample, and then executes a bag within the userÕs budget constraints. Previous work has shown the efficacy of this approach.

 

In this presentation, I will present recent developments, among which are the use of paid-for-but-idle machines during the tail phase of an execution and the use of spot market instances.

Title:

Efficient GPU cluster implementation of the lattice Boltzmann method

 

Abstract:

The lattice Boltzmann method (LBM) is an innovative and promising approach in computational fluid dynamics. From an algorithmic standpoint it reduces to a regular data parallel procedure and is therefore, well-suited to high performance computations. Numerous works report efficient implementations of the LBM for the GPU, but very few mention multi-GPU versions and even fewer GPU cluster implementations. Yet, to be of practical interest, GPU LBM solvers need to be able to perform large scale simulations. In the present contribution, we describe an efficient LBM implementation for CUDA GPU clusters. Our solver consists of a set of MPI communication routines and a CUDA kernel specifically designed to handle three-dimensional partitioning of the computation domain.  Performance measurements were carried out on a small cluster. We show that the results are satisfying, both in terms of data throughput and parallelisation efficiency.

An Incomplete Metamorphosis of GEO Grid into GEO Cloud

 

Abstract:

The "GEO Grid" project since 2005 is primarily aiming at providing an E-Science infrastructure for worldwide Earth Sciences community. In the community there are wide varieties of existing data sets including satellite imagery, geological data, and ground sensed data that each data owner insists own licensing policy. Also, there are so many of related projects that will be configured as virtual organizations (VOs) enabled by Grid technology. However, Time flies quickly. The technologies we have brought to build the GEO Grid had too rich capability so that the cost of its operation rose higher. In fact the design was made by listening voices of users, data owners and operation managers, but it made the system more complicated. Recently, we have decided to move those systems into cloud space and recaptured its easy operation. I will demonstrate some of our experience and findings on metamorphosing the GEO Grid into Cloud.

Title:

Towards Computing as a Utility via Adaptive Middleware

 

Abstract:

With the increasing maturation of grids and clouds, the vision of computing as a utility, is starting to become a reality. However, usability of such platforms for executing science and engineering applications is a challenge. In order for these applications to utilize resources ranging from on-premise to federated to on-demand platforms, they often need target-specific adjustments and reconciliations -- which pose considerable logistical and efficiency obstacles.  This talk will describe the proposed design of adaptive middleware to enhance the executability of applications on varied computational back-ends. Preliminary experiences with use cases that measure the feasibility and issues with cross platform computing will be discussed.
