Deadlock avoiding

Future Perspective on Flexible Device. In the conventional computing paradigm, deadlock can be avoided in the software level, if it is possible to prescribe an appropriate resource allocation protocol comprehending potential resource requests from all processes. However, no programmer can know what the processes will request in advance of the coding without actual executions. This means that deadlock avoidance is often impossible for many practical systems. On the other hand, our system flexibly breaks through the livelock-hke... 

A modified version of the C function in Figure 3.1 using an MPI non-blocking receive, MPI Irecv, to avoid deadlock. The MPI Irecv returns without waiting for any message to arrive, and each process then proceeds to post the sending operation, MPI Send. The MPI Wai t causes each process to wait at this point until the message to be received by MPI Irecv has arrived. The employed MPI functions are explained in Appendix A.

After partitioning, interconnection binding is carried out. This process tries to avoid interconnection binding deadlocks. The goal is to transfer CBB results on one horizontal bus, i.e., the corresponding variable should be used at the same operand position by all successor operations. In addition, the number of transfers on each bus system is balanced in every control step. A heuristic has been developed, which is similar to the...

Barbosa et al. (1989) have proved that, under the SER, all nodes will operate the same number of times in a long enough interval of time, avoiding deadlocks and starvation. The interval of time between operations of a node and the number of...
