One of the main obstacles in obtaining high performance from message-passing multicomputer systems is the inevitable communication overhead which is incurred when tasks executing on different processors exchange data. https://doi.org/10.1016/j.parco.2006.06.006. /CropBox [0.0 0.0 612.0 792.0] In this paper, we propose a static scheduling algorithm for allocating task graphs to fullyconnected multiprocessors. <>stream Real-time systems will be large and complex, their activities cooperating intensely [7]. ��� P�!~|���o�9�.+� H_P�ț�V����u��B�z�X����{s�����.���A�L>��f���˛�Y�t��_�( :������7?�����۷?�)p >'�f�cW�a��|���ϟݼ���Ka'@oH�1�G��䝠o^��~�?3�����$��6�@(��m����O��,s�,2���� l�@2���3䋿Է�%�+F�@X�Kd�je�*��_��~������ШT Nevertheless, obtaining peak performances on irregular applications such as computer algebra problems re-mains a ...". << x�S�*�*T0T0 B�����i������ y�+ 8, No. periodic task model may be too inaccurate and can lead to undue under utilization of the processor *Z5kQx���L�$���Zݥr�/�L�]Ԁ:��`�1�!j cJ��XΙF�f�a`���ڨ��VZR`EXru�%�f�7| distributed hard real-time system    Each algorithm, protocol, or mechanism is defined by pseudo code or /Type /Page Many algorithms for scheduling DAGs on multiprocessors have been proposed, but there has been little work done to determine their effectiveness.
