Version 1.1.0

Added

• Added support for XDMoD version 8.0.
• Added --dry-run option to summarize_jobs.py script (used for testing purposes).
• Added extra options to summarize_jobs.py to support more fine-grained selection of jobs to process
• Added supremm-upgrade script to facilitate database migrations needed for a 1.0.5 to 1.1.0 upgrade.
• Added multiprocessing support to indexarchives.py.
• Added option to indexarchives.py to estimate the archive timestamp of job level archives from the filename. This dramatically improves
  the performance on parallel filesystems that have large number of files per directory.
• Added plugin that detects periodic patterns in timeseries data.
• Added GPU usage timeseries plugin.
• Added AMD Interlagos support to the plugins that use hardware performance counters.
• Added effective CPU usage metrics to the CPU usage plugin. This generates CPU usage statistics for
  the subset of CPUs that had any usage during a job.
• Added summarize_mpi.py script that uses MPI for process management. This can be used on an HPC cluster to summarize jobs in parallel across multiple compute nodes.
• Added ability to preprocess counter metrics that have < 64 bit range to 64 bit range counters.
• Added ability to call the dynamic library version of pmlogextract. This
  mode of operation is intended to be used when running the summarization
  software as an MPI job on a compute resource that does not allow python-based
  MPI software to execute the fork() system call.

Changed

• Updated PCP configuration templates.
• Rewrote the main kernel of the summarization software in Cython. This improves the performance of the software.
• Changed structure of the database tables that store PCP archive metadata. This improves the query performance.
• Changed load balancing algorithm in multiprocessing mode to more evenly distribute work among processes.
• Job summary documents now record the time when they were created.
• Improved performance of the SlurmProc preprocessor.
• Changed the process detection algorithm in SlurmProc to output processes in frequency order.

Fixed

• Improved error handling for invalid data in PCP archives in several plugins (#172, #164, #135)
• indexarchives.py script no longer exits if an unreadable file or directory is seen.
• Job script parser now handles parsing PBS/Torque job array elements.
• Improved error handling in summarize_jobs.py if the connection to the mysql server closes during processing.

Misc

• Centos 6 and python 2.6 are no longer supported.
