Caliper 2.4.0

Caliper 2.4.0 brings improvements and new features, including

• New loop-report and mpi-report ConfigManager configs
• New Fortran wrappers for the annotation API
• Fortran and C wrappers for the ConfigManager API
• Low-frequency performance measurement modes ("monitor modes")
• Easier and more robust linking and initialization

Caliper 2.3.0

Caliper 2.3.0 brings improvements and new features, including

• All-around improved robustness
• New PAPI service
• Kokkos profiling support
• Inclusive time and percentage calculation for the runtime-report config
• Top-down analysis for Intel Skylake CPUs (experimental)

Caliper 2.2.0

Caliper 2.2.0 brings lots of improvements and new features, including

• Many improvements to the ConfigManager API and syntax
• Support for metadata collection with adiak
• Collection of I/O metrics (bytes read/written, read/write bandwidth) for POSIX and C I/O
• Record memory high-water mark
• New hatchet-region-profile and hatchet-sample-profile ConfigManager configurations to collect profile data for analysis with hatchet

Caliper 2.1.1

This is a bugfix release. It addresses some issues in the ConfigManager API and runtime-report controller, restores the ability to cycle through different colors in the nvprof/nvtx annotation bindings, and makes the alloc.total_size attribute aggregatable.

Caliper 2.1.0

Caliper 2.1.0 brings improvements and new functionality, including

• Simplified linking: libcaliper is now self-contained, linking -lcaliper (or -lcaliper-serial for non-MPI programs) includes all caliper modules. It is no longer necessary to add libcaliper-mpi for MPI programs or libcaliper-reader, libcaliper-common, etc. when linking statically.
• ConfigManager: A new, easy interface to enable and control built-in Caliper configuration profiles such as runtime-report from within applications.
• ChannelController: A new interface to simplify creation of custom, application-controlled Caliper configuration profiles.
• RegionProfile: A new interface that lets applications collect and access timing info for annotated Caliper regions directly.
• The new cpuinfo service reports CPU id and NUMA node where a snapshot was taken.
• Various improvements in the table and tree output formatters.
• Gotcha 1.0.2 now comes bundled with Caliper.

Caliper 2.0.1

This is a minor release that fixes compilation with PGI and BG/Q compilers.

Caliper 2.0.0

Caliper 2.0.0 is a major release with new functionality:

• The new Channel API allows multiple, independent measurement configurations to be active at the same time. It also provides better abilities to create Caliper configurations and control measurements programmatically.
• Many internal optimizations and API improvements.

Caliper 1.9.1

This bugfix release fixes compilation with PGI compilers and a bug in the caliper-reader library.

Caliper 1.9.0

Caliper 1.9.0 contains bug fixes and new functionality, including

• Ability to group by attribute properties or flags in CalQL
• Attribute aliases in some output formatters
• Updated TAU service
• cali_mpi_init() function for explicit initialization of the Caliper MPI runtime library

Caliper 1.8.0

Caliper 1.8.0 contains bug fixes and new functionality, including

• The cuptitrace service to collect asynchronous CUDA event traces through CUpti
• New inclusive_sum aggregation kernel
• New built-in configuration profiles mpi-runtime-report and mpi-msg-trace
• Fixes for the Fortran, C and C++ annotation APIs
