In building concurrent FIFO queues this reasoning has led re searchers to propose combiningbased concurrent queues This paper takes a different approach showing how to rely on fetchandadd FA a less powerful primitive that is available on x86 process Ticket #273. Introduction. I/O is . one . of the main bottlenecks in HPC applications.. Many applications or higher level libraries rely on MPI-I/O for doing parallel I/O.. Several optimizations have been introduced in MPI-I/O to meet the needs of application. Pavan Balaji. 1. , Darius Buntinas. 1. , David Goodell. 1. , William Gropp. 2. , and Rajeev Thakur. 1. 1 .
