  • Latency Avoiding by Adequate Mapping  
  • by Jens Mache — 1994
  • …What to do if the number of processes your algorithm uses in parallel is bigger than the number of processors your parallel machine has? That's when mapping comes into play. But let's be careful: Mapping affects the load balance and the number of remote accesses (with the latter causing latency). Th…

  • Dispersal Metrics for Non-Contiguous Processor Allocation  
  • by Jens Mache, Virginia Lo — 1996
  • …Resource management is a key area in the drive to fully realize the performance potential of parallel and distributed systems. For the task of assigning a set of processors of a massively parallel processing (MPP) system to a given job, various processor allocation strategies have been proposed i…

  • The Effects of Dispersal on Message-Passing Contention in Processor Allocation Strategies  
  • by Jens Mache, Virginia Lo — 1997 — In Proc. Third Joint Conference on Information Sciences, Sessions on Parallel and Distributed Processing
  • …Processor allocation is a key task in the drive to fully realize the performance potential of massively parallel processing (MPP) systems. With the advent of the class of non-contiguous processor allocation strategies, the allocation performance bottleneck shifted from fragmentation to message-passi…

  • Minimizing Message-Passing Contention in Fragmentation-Free Processor Allocation  
  • by Jens Mache Virginia Lo, Jens Mache, Virginia Lo, Kurt Windisch — 1997 — In Proceedings of the 10th International Conference on Parallel and Distributed Computing Systems
  • …Processor allocation, the spatial assignment of a set of processors to each scheduled job, is an important issue in the drive to fully realize the performance potential of massively parallel supercomputers. With the advent of non-contiguous processor allocation strategies, the fragmentation problem …

  • Ray Tracing on Cluster Computers  
  • by Jens Mache, Robert Broadhurst, Jeffrey Ely — 2000
  • …The creation of ever more realistic images is central to many fields ranging from the animation industry to education, and ray tracing is one of the most popular and powerful means by which photo-realistic images can be created. In this paper, we report on porting, measuring and optimizing a ray tra…

  • The Impact of Spatial Layout of Jobs on Parallel I/O Performance  
  • by Jens Mache, Virginia Lo, Marilynn Livingston, Sharad Garg — 1999 — In IOPADS ’99: Proceedings of the sixth workshop on I/O in parallel and distributed systems
  • …Input/Output is a big obstacle to effective use of teraflopsscale computing systems. Motivated by earlier parallel I/O measurements on an Intel TFLOPS machine, we conduct studies to determine the sensitivity of parallel I/O performance on multi-programmed mesh-connected machines with respect to numb…

  • Contour Tracking: A Comprehensive Student Project for Sensor Network Education  
  • by Damon Tyman, Akshay Dua, Jens Mache, Nirupama Bulusu — In Proceedings of ACM SIGCOMM Conference on Applications, Technologies, Architectures, and Protocols for Computer Communications
  • …Wireless sensor networks are poised to become an ubiquitous part of the computing landscape. We are developing and class-testing sensor network lab exercises. The goal is to enable undergraduate students to learn sensor network concepts in a hands-on manner, and build sensor networking applications.…
