  • Bestavros, Azer; Carter, Robert L.; Crovella, Mark E.; Cunha, Carlos R.; Heddaya, Abdelsalam; Mirdad, Sulaiman A. (Boston University Computer Science Department, 1995-01-15)
    With the increasing demand for document transfer services such as the World Wide Web comes a need for better resource management to reduce the latency of documents in these systems. To address this need, we analyze the ...
  • Fahmy, Amr; Heddaya, Abdelsalam (Boston University Computer Science Department, 1996-09-20)
    Communication and synchronization stand as the dual bottlenecks in the performance of parallel systems, and especially those that attempt to alleviate the programming burden by incurring overhead in these two domains. We ...
  • Heddaya, Abdelsalam; Sinha, Himanshu (Boston University Computer Science Department, 1996-03-07)
    Programmers of parallel processes that communicate through shared globally distributed data structures (DDS) face a difficult choice. Either they must explicitly program DDS management, by partitioning or replicating it ...
  • Heddaya, Abdelsalam; Sinha, Himanshu (Boston University Computer Science Department, 1993-06-04)
    Coherent shared memory is a convenient, but inefficient, method of inter-process communication for parallel programs. By contrast, message passing can be less convenient, but more efficient. To get the benefits of both ...
  • Heddaya, Abdelsalam; Park, Kihong (Boston University Computer Science Department, 1994-02-07)
    For communication-intensive parallel applications, the maximum degree of concurrency achievable is limited by the communication throughput made available by the network. In previous work [HPS94], we showed experimentally ...
  • Heddaya, Abdelsalam; Fahmy, Amr (Boston University Computer Science Department, 1994-12-05)
    Predictability -- the ability to foretell that an implementation will not violate a set of specified reliability and timeliness requirements -- is a crucial, highly desirable property of responsive embedded systems. This ...
  • Heddaya, Abdelsalam; Helal, Abdelsalam (Boston University Computer Science Department, 1997-12-04)
    Reliability and availability have long been considered twin system properties that could be enhanced by distribution. Paradoxically, the traditional definitions of these properties do not recognize the positive impact of ...
  • Bestavros, Azer; Chen, Marina; Crovella, Mark; Heddaya, Abdelsalam; Sclaroff, Stan; Cowie, James (Boston University Computer Science Department, 1996-03-21)
    The exploding demand for services like the World Wide Web reflects the potential that is presented by globally distributed information systems. The number of WWW servers world-wide has doubled every 3 to 5 months since ...
  • Heddaya, Abdelsalam; Park, Kihong; Sinha, Himanshu (Boston University Computer Science Department, 1993-06-04)
    Parallel computing on a network of workstations can saturate the communication network, leading to excessive message delays and consequently poor application performance. We examine empirically the consequences of integrating ...
  • Heddaya, Abdelsalam; Mirdad, Sulaiman (Boston University Computer Science Department, 1996-10-10)
    Document publication service over such a large network as the Internet challenges us to harness available server and network resources to meet fast growing demand. In this paper, we show that large-scale dynamic caching ...
