  ABSTRACT = {{\bf Introduction:} The extent of repeats is a striking feature of genomic
DNA sequences. For example, families of repeat sequences account for
about one half of the human genome. Finding repeats is useful in
finding defective genes and in forensic DNA fingerprinting. Techniques
to find repeats can also be used to find signatures for a pair (or a set)
of genomes. We consider the problem of finding repeats and
signatures in genomic sequences using grid-computing techniques.
\\
{\bf Methods:} The problem is clearly compute-intensive and creates costly
bottlenecks in large-scale analyses. There are a number of programs
available for finding repeats, such as the popular RepeatMasker [REF].
We have implemented an algorithm based on suffix arrays for finding
repeats, which was then ported to run on MPI clusters with dynamic
load balancing. This algorithm also searches for direct repeats and
other variants such as inverted repeats and complemented inverted
repeats. We have also implemented an algorithm that searches for
“signatures”, i.e., subsequences present in one genome but absent
from the others.
\\
{\bf Results and Conclusions:} We have successfully tested our
implementation on five strains of the bacteria Pseudomonas
aeruginosa, each containing over six million nucleotides. The MPI
cluster implementation resulted in near-optimal speedup and
balancing.

The goal  of WRF is to improve weather prediction, especially in the case of hurricane mitigation. Optimum forecasting consists of:
Accurate and Timely Results and Precise Location Information.
Grid-Enablement is the practice of taking  existing applications that are currently configured to run on a single machine or cluster and adapting them to run on a non-homogeneous resources connected via the internet with the goal of improving its performance (execution time and resource utilization).
The expected benefits of  successful grid-enablement to WRF will be:
1) Access to a greater number of compute resources due to the utilization of more domains; 
2) Faster results, by virtue of having more compute power (more power = less simulation time); and
3) Improved precision of results (more power = higher domain granularity).
The meta-scheduler is the “global” scheduler of the grid environment – above the local schedulers.  Its function is to select the best resources for a job to run on by analyzing application and target architecture characteristics to find the best match for optimal resource usage and job return time. Performance prediction provides:
 1) the meta-scheduler with accurate prediction run times  -  “smarter” scheduling; and 
 2) at local level, improved resource allocation and local scheduling techniques as many users overestimate job execution times for precautionary reasons.

Furthermore, forging working relationships with our international collaborators serves as a big step towards making breakthrough contributions to the research community.
Beyond the walls of research, PIRE afforded us the opportunity to develop as individuals, both professionally and personally.  We were given the opportunity to really explore the world and take on a trailblazing role in this the first year of this program.  As some what of guinea pigs, we were able to set the bar for the years to come in this program and were ambassadors for our home institutions.  The experiences we gathered here will be invaluable in the rest of our academic careers as well as our subsequent professional careers.

In this project, we use existing and custom-designed profiling and code inspection tools to understand the runtime behavior of {WRF} on a Grid computing environment. Our goal is to produce a mathematical model to predict the allocation of computing resources, for example, the optimized number of homogenous nodes required for a hurricane path prediction simulation. We will run a number of profiling experiments with different hardware and software configurations. The data gathered through these experiments will help us formulate and validate the mathematical model. This model will enable future self-configured executions of the {WRF} code on a Grid computing environment.

  ABSTRACT = {The Latin American (LA) Grid Weather Research and Forecast ({WRF}) Portal is aimed to provide a comprehensive Web-based user-friendly interface for meteorologists to conduct their research and forecast, for end users to access and understand the forecast, and for system administrators to configure the underlying computing infrastructure. This way, the meteorologist will spend their time only on the science part of weather research and forecast instead of wasting their time on tedious and error-prone tasks of compiling, installing, and configuring the {WRF} code. The end users (e.g., business owners, home owners, and emergency response teams) can easily access the forecast that most relates to them and assists their understanding of how to take preventive and recovery actions accordingly. The system administrators can add or remove computational resources (e.g., clusters, supercomputers, and virtual machines) to be allocated dynamically to the different simulation tasks based on some high-level policies.  Currently, we are focusing on enabling the meteorologist to set up, automate simulations and organize data results to support ensemble runs of hurricane forecast simulations leveraging grid computing resources.

  ABSTRACT = {The use of local resource management systems to schedule the execution of jobs is extended through many research areas in need of high performance computing. However, while local schedulers manage the rights for a single domain, there is a need to perform a higher level scheduling of resources. A meta-scheduler, or a scheduler of schedulers, is an entity in charge of orchestrating these resources from different organizations. Different architectures have been proposed for meta-scheduling systems. In this poster, we present a hybrid approach, combining hierarchical and peer-to-peer architectures to improve fault tolerance, management and extensibility of these systems. We also define a standard protocol to allow different meta-scheduler instances to communicate using Web Services. In our experiment, three remote organizations using different scheduling technologies (namely, IBM, BSC, and FIU) interoperate using the described protocol.

The lack of an appropriate programming model for grid computing is a major inhibitor in the emergence of grid-enabled applications, which is a focal point of the computer science and engineering portion of the project. In this project, we aim to address this issue by integrating Transparent Shaping developed at FIU, which allows introduction of static and dynamic adaptation in applications, and GRID Superscalar developed at BSC, which allows conversion of a sequential code to a parallel code ready to be run in the grid. This new programming model will include a supporting runtime and middleware that adapts execution of grid-enabled applications as a response to the changes in the grid environment (e.g., the availability of resources such as the number of available computational nodes, the available network bandwidth, and the available data storage). Development work will be carried out first at FIU by selected students and will be supervised by Masoud Sadjadi and then by Rosa M. Badia at BSC.

    Florida International University (FIU-SCIS) as a proof of concept to the 
    usefulness of data mining in autonomic system management. Autonomic System 
    Manager is a software system that helps system and network administrators 
    with their complex job. It automatically monitors Net flow (network flow) 
    data and responds to anomalies in an adaptive fashion. The current focus of 
    this prototype is on network anomaly detection.  The purpose of anomaly 
    detection is to detect and categorize situations that deviate from the normal 
    baselines. Network and system administrators receive a torrent of IP requests 
    everyday. As is the case with any network, some events are malicious. In order 
    to secure a network system effectively administrators need to use tools that 
    have the capability to classify malicious activities and respond to threats 
    in real time. The principle challenge in automatically detecting insidious 
    intruders is that the range of anomalous activities is huge, ranging from port 
    scans, denial of service attacks, ping of death, SYN flooding, UDP flooding, 
    worms, viruses, and disconnecting models remotely.

However, comparable advances are needed in the designof mobile computing applications and supporting middleware.Distributed software must be able to adapt to dynamic situationsrelated to several cross-cutting concerns, includingquality-of-service, fault-tolerance, energy management, andsecurity. We previously introduced Adaptive Java, an extensionto the Java programming language, which provides languageconstructs and compiler support for the development of adaptive middleware.This paper describes the use of Adaptive Java to develop anadaptable communication component called the MetaSocket.MetaSockets are created from existing Java socket classes, buttheir structure and behavior can be adapted at run time inresponse to external stimuli. We are using MetaSockets forseveral distributed computing tasks, including audits of traffic patternsfor intrusion detection, adaptive error control on wirelessnetworks, and dynamic energy management for handheld and wearablecomputers. This paper focuses on the internal architecture and operation ofMetaSockets. In particular, we describe in detail howadaptive behavior is implemented and how MetaSockets interact with other adaptive components, such as decision makersand event mediators. Results are presented from experimentson a mobile computing testbed in which MetaSockets respond to dynamic wireless channel conditionsin order to improve the qualityof interactive audio streams delivered to iPAQ handheld computers.},
