SUMMARY:From Monitoring to Process Placement a Complete Workflow for Optim
 izing Data Management at System Scale
DESCRIPTION:Minisymposium\n\nFrom Monitoring to Process Placement a Comple
 te Workflow for Optimizing Data Management at System Scale\n\nJeannot\n\nD
 ata management and especially communication optimization is one of the key
  techniques to achieve performance and scalability of high-performance com
 puting applications. One of the interesting techniques for minimizing comm
 unication cost and data exchange between processes is to perform a careful
  process placement. The process placement consists in allocating the proce
 sses of the parallel application to the computing resources in order to re
 duce the network traffic. For instance, process that exchange a lot of dat
 a should be mapped close to each other according to the topology. To do so
 , several steps have to be carried out. First, it requires to monitor the 
 communication pattern. Second it needs to gather the topology where the ap
 plication is going to be executed. Then an algorithm computes the process 
 mapping based on these two pieces of information. Last, the mapping is enf
 orced for the execution. In this presentation, I will describe our contrib
 ution in all these dimensions of the problem. Presenting the tools we have
  developed as well as the results displaying performance improvement.\n\nD
