Heterogeneous distributed computing is found in a variety of fields
including scientific computing, Internet and mobile
devices. Computational grids focusing primarily on
computationally-intensive operations have emerged as a new infrastructure
for high performance computing. Specific algorithms such as
scheduling, load balancing and data redistribution have been devised
to overcome the limitations of these systems and take full advantage
of their processing power. However, experimental validation and
fine-tuning of such algorithms require multiple heterogeneous
platforms and configurations.
EHGrid is a computational grid
emulator based on the heterogeneous emulator Wrekavoc. EHGrid
reshapes the virtual topology of a homogeneous cluster, degrades the
performance of the processors and modifies the characteristics of
the network links in an accurate, independent and reproducible
way.
EHGrid borrows the core concept and
