In many large threaded applications, synchronizing all of the threads by use of barriers can results in significant wasted processing time. If the application lends itself, loosely synchronous barriers instead of strictly synchronous barriers should be used and can recover lost time.The post Phasing Barriers for Performance appeared first on insideHPC.

"Metadata, or data about data, lets scientists find the valuable data they are looking for. Metadata especially helps find value in data that’s been created by others, no matter when or where. Without rich metadata, scientists increasingly risk spending their time just looking for data, or worse, losing it – instead of exploiting that data for analysis and discovery."The post Keeping Up with the Growth of Scientific Data appeared first on insideHPC.
