This quantity set LNCS 7016 and LNCS 7017 constitutes the refereed court cases of the eleventh foreign convention on Algorithms and Architectures for Parallel Processing, ICA3PP 2011, held in Melbourne, Australia, in October 2011.
The first quantity provides 24 revised usual papers and 17 revised brief papers including the summary of the keynote lecture - all rigorously reviewed and chosen from eighty five preliminary submissions. The papers disguise the various dimensions of parallel algorithms and architectures, encompassing primary theoretical ways, useful experimental effects, and advertisement elements and platforms and concentrate on huge parts of parallel and dispensed computing, i.e., architectures, algorithms and networks, and platforms and applications.

Sample text

Timeout strategy has been proposed associating costs for waiting time and retransmission attempts [6] where the timeout value was set to minimize the overall expected cost. The goal of this work was to reduce the number of retransmission attempts. In [7] a scheme was proposed for Deterministic Timeouts for Reliable Multicast (DTRM) to avoid negative feedback explosion [7]. DTRM ensures that retransmission caused by only one NACK from a receiver belonging to a sub-tree arrives early enough so that the timers do not expire in the other receivers in that sub-tree.

For each ray in the input data, the block will search for its own identifier in the traversal list, as in lines 3 and 4. Then, if there are any triangles in the block, parallel intersection tests are performed by the threads. Finally, one of the threads (the Massively Parallel Identification of Intersection Points 21 Table 1. 12 *All times are in seconds. Low-res Stanford Bunny 3-D scene. one with identifier zero) searches the smallest result (that is closest to the ray origin, in respect to that block) from the array of shared results, as in line 8.

  VArrayLogNode Writing and Committing to a VArray. Writing to a VArray is similar to writing to a VBox: the value to be written is added to the transaction’s write-set. During the commit, the write-back to a VArray proceeds as follows: 1. Create a new log entry with the indexes of the array positions that are going to be overwritten and add that entry to the head of the log; 2. Update the array version; 3. Finally, backup to the log and write-back each changed array position.
