Communication strategies for out-of-core programs on distributed memory machines
1995
Proceedings of the 9th international conference on Supercomputing - ICS '95
Preserved Fulltext
In this paper, we show that communication in the outof-core distributed memory problems requires both interprocessor communication and file 1/0. ...
We first describe how the communication is done for in-core programs and then describe three communication strategies for out-of-core programs. ...
The overall time required for an out-of-core program can be computed as a sum of times for local 1/0 Tl,o, in-core computation TCO~P and communication
