Server farms are ubiquitous in applications ranging from Web server farms to high-performance supercomputing systems to call centers. The popularity of the server farm architecture is understandable, as it allows for increased performance, while being cost-effective and easily scalable.
Given the prevalence of server farms, it is surprising that even at this late date so little is understood regarding their performance as compared with their single-server counterpart, particularly with respect to scheduling. Part of the problem is that there are at least three disjoint communities studying scheduling in server farms, including the SIGMETRICS community, the INFORMS community, and the SPAA/STOC/FOCS community, all of which have different approaches and goals. One of our goals in this talk is to make researchers aware of results in these different communities.
