While cloud proponents tout availability and cost-efficiency as reasons for widespread adoption, in practice cloud resources are often used inefficiently as users lack methods to easily and efficiently scale applications while taking into account the underlying economic models on which the cloud is built. In this talk, I will introduce two projects that aim to enable scalable and cost-efficient use of cloud platforms. First, I will describe Parsl---a parallel scripting library for Python that enables seamless and elastic execution of parallel workflows on clouds, clusters, and supercomputers. Second, I will describe methods for predicting cloud market dynamics and application performance on arbitrary cloud instances. Collectively, these approaches simplify access to on-demand computing infrastructure and improve the efficiency with which applications can be executed on the cloud.<br class=""> <br class=""></font><b class=""><i class=""><font face="Cambria" size="4" class="">Bio:</font></i></b></div><div class="" style="orphans: 2; widows: 2;"><font face="Cambria" size="4" class=""><i class="">Kyle Chard is a Senior Researcher at the University of Chicago and Argonne National Laboratory.
