Title:  Scheduling in heterogeneous virtualised clusters
	(Thesis Proposal Review seminar)

Abstract

  Clusters of commodity processors are highly heterogeneous in nature. The
  volume of computation performed by one compute node in the cluster can
  be drastically different from other nodes due to architectural or
  communication interconnect differences. The conventional scheduling
  solutions do not take detailed heterogeneity aspects into consideration,
  and thus are not very effective.

  Virtualisation can be utilized to normalize the heterogeneity of a
  cluster to some extent. With growing maturity and hardware support, the
  performance gap between native and virtualised operating systems is
  decreasing making it a good candidate for high performance computing
  (HPC).

  The concept of live migration of operating systems can be utilized to
  maximize the throughput of the compute farm and the turnaround times of
  the submitted jobs. This can be done by developing a run-time job
  estimation and remapping service capable of determining more optimized
  hardware environment for a job at runtime, resulting in high throughput
  and improved turnaround times in the compute cluster.

  This seminar will discuss the prospects of using virtualisation in HPC
  and some proposed solutions. we will also present some early results of
  our experiments with virtualised compute clusters and discuss the short-
  comings of current Virtualisation solutions with HPC viewpoint.
