These assumptions are not true today. Today, emerging web services require data centers that scale to hundreds of thousands of servers, i.e., hyperscale, to efficiently process requests from billions of users. In this new era of hyperscale computing, we can no longer afford to build each layer of the systems stack separately. Instead, we must rethink the synergy between the software and hardware worlds from the ground up.</span></div><span class="" style="font-size: 15px;"> <br class="">In this talk, I will focus on re-thinking (1) software threading and concurrency paradigms and (2) data center hardware architectures. First, I will describe μTune, my software threading framework that is aware of the overheads induced by the underlying hardware's constraints. Then, I will discuss SoftSKU and Accelerometer—my proposals to answer the question of: How should we build data center hardware for emerging software paradigms in the post-Moore era? Finally, I will conclude by describing my ongoing and future research towards re-designing the systems stack to enable the hyperscale web services of tomorrow.</span></div><div class=""><span class="" style="font-size: 15px;"><br class=""></span></div><div class=""><div class=""><font class=""><span class="" style="font-size: 15px;"><div class="" style="font-variant-ligatures: normal; background-color: rgb(255, 255, 255);"><div class=""><font class=""><b class="" style="color: rgb(33, 33, 33);">Bio: </b></font>Akshitha Sriraman is a Ph.D. candidate in Computer Science and Engineering at the University of Michigan.
