Zombie Processes are Eating your Memory

Randon ASCII

Zombies probably won’t consume 32 GB of your memory like they did to me, but zombie processes do exist, and I can help you find them and make sure that developers fix them. He’d even written a tool that would dump a list of zombie processes – their names and counts. I ran his tool and it showed 506,000 zombie processes!

File systems unfit as distributed storage backends: lessons from ten years of Ceph evolution

The Morning Paper

File systems unfit as distributed storage backends: lessons from 10 years of Ceph evolution Aghayev et al., In this case, the assumption that a distributed storage backend should clearly be layered on top of a local file system. A distributed file system provides a unified view over aggregated storage from multiple physical machines.

Tuning SQL Server Reporting Services

SQL Performance

SSRS 2008 brought that component into the reporting service module. The ReportServer and ReportServerTempDB databases are SQL Server databases and should be part of a regular backup process, just like other user databases. Unlike the system database tempdb, ReportServerTempDB is not recreated at startup.

The Surprising Effectiveness of Non-Overlapping, Sensitivity-Based Performance Models

John McCalpin

The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).
