A Grid Portal for an Undergraduate Parallel Programming Course
(Institute of Electrical and Electronics Engineers, 2005-08)
[Abstract] This paper describes an experience of designing and implementing a portal to support transparent remote access to supercomputing facilities to students enrolled in an undergraduate parallel programming course. ...
Analysis of Performance-impacting Factors on Checkpointing Frameworks: The CPPC Case Study
(Oxford University Press, 2011-11-01)
[Abstract] This paper focuses on the performance evaluation of Compiler for Portable Checkpointing (CPPC), a tool for the checkpointing of parallel message-passing applications. Its performance and the factors that impact ...
A Heuristic Approach for the Automatic Insertion of Checkpoints in Message-Passing Codes
(Technische Universitaet Graz * Institut fuer Informationssysteme und Computer Medien,Graz University of Technology, Institute for Information Systems and Computer Media, 2009-08)
[Abstract] Checkpointing tools may be typically implemented at two different abstraction levels: at the system level or at the application level. The latter has become a more popular alternative due to its flexibility and ...
Extending the Globus Information Service with the Common Information Model
(IEEE Computer Society, 2011-07-14)
[Abstract] The need of task-adapted and complete information for the management of resources is a well known issue in Grid computing. Globus Toolkit 4 (GT4) includes the Monitoring and Discovery System component (MDS4) to ...
Integrating the common information model with MDS4
(IEEE Computer Society, 2008-10-31)
[Abstract] The management and monitoring of static and dynamic resources is a key issue in grid environments. Information models are an abstract representation of software and hardware aspects of these resources, a common ...
Exploiting locality in the run-time parallelization of irregular loops
(C R C Press, LLC, 2002-12-10)
[Abstract] The goal of this work is the efficient parallel execution of loops with indirect array accesses, in order to be embedded in a parallelizing compiler framework. In this kind of loop pattern, dependences can not ...
A 2D algorithm with asymmetric workload for the UPC conjugate gradient method
(Springer New York LLC, 2014)
[Abstract] This paper examines four different strategies, each one with its own data distribution, for implementing the parallel conjugate gradient (CG) method and how they impact communication and overall performance. ...
CPPC: a compiler‐assisted tool for portable checkpointing of message‐passing applications
(John Wiley & Sons Ltd., 2010-11-19)
[Abstract] With the evolution of high‐performance computing toward heterogeneous, massively parallel systems, parallel applications have developed new checkpoint and restart necessities. Whether due to a failure in the ...
Compiler-Assisted Checkpointing of Parallel Codes: The Cetus and LLVM Experience
(Springer New York LLC, 2013)
[Abstract] With the evolution of high-performance computing, parallel applications have developed an increasing necessity for fault tolerance, most commonly provided by checkpoint and restart techniques. Checkpointing tools ...
Clupiter: a Raspberry Pi mini-supercomputer for educational purposes
(Institute of Electrical and Electronics Engineers, 2024)
[Abstract]: The main objective of this work is to bring supercomputing and parallel processing closer to non-specialized audiences by building a Raspberry Pi cluster, called Clupiter, which emulates the operation of a ...
