Many-task computing (MTC) aims to bridge the gap between two paradigms, high-throughput computing (HTC) and high-performance computing (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, where the primary metrics are measured in seconds, not operations per month. MTC denotes high-performance computations comprising of multiple distinct activities, coupled via file system operations. Tasks may be small or large, uniprocessor or multiprocessor, compute-intensive or data-intensive,…mehr

Produktbeschreibung
Many-task computing (MTC) aims to bridge the gap
between two paradigms, high-throughput computing
(HTC) and high-performance computing (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, where
the primary metrics are measured in seconds, not
operations per month. MTC denotes high-performance
computations comprising of multiple distinct
activities, coupled via file system operations. Tasks
may be small or large, uniprocessor or
multiprocessor, compute-intensive or data-intensive,
static or dynamic, homogeneous or heterogeneous. 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 message passing interface commonly found in
HPC, drawing attention to the many computations that
are heterogeneous but not happily parallel. This
book explores fundamental issues in defining the MTC
paradigm, as well as theoretical and practical issues
in supporting compute and data intensive applications
on large scale systems.
Autorenporträt
Ioan Raicu holds a PhD in Computer Science from University of
Chicago under Dr. Ian Foster s guidance. His interests are in
distributed systems, focusing on a new paradigm Many-Task
Computing, aiming to bridge the gap between two paradigms,
High-Throughput Computing and High-Performance Computing. His
work has been funded by NASA, NSF, and DOE.
