Unlike Scalasca 1.x, the Scalasca 2.x release series is based on the community instrumentation and measurement infrastructure Score-P, which is jointly developed by a consortium of partners from Germany and the US. This significantly improves interoperability with other performance analysis tool suites such as Vampir and TAU due to the usage of the two common data formats CUBE4 for profiles and the Open Trace Format 2 (OTF2) for event trace data.

    • Fix build issues on Cray systems, now also properly taking CRAYPE_LINK_TYPE setting into account
  • Automatic trace analyzer changes & improvements:
    • Fix rare crash/deadlock in critical-path/delay analysis while analyzing MPI persistent communication.
    • Improved memory management.
    • Improved handling of OTF2 traces in SIONlib containers.
    • Improved trace reading times, especially at scale.
    • Fixed detection of wait states in active-target synchronization based on EPIK traces
  • Code refactoring and various bug fixes.

Supported Platforms

The Scalasca tool set has been successfully tested on the following platforms:

  • IBM Blue Gene/Q
  • IBM BladeCenter & iDataPlex clusters
  • Cray XC series
  • Fujitsu FX10, FX100, and K computer
  • various Linux-based clusters (x86_64, Power8, armhf, AArch64)
  • Intel Xeon Phi (native mode only)

The following platforms have not been tested recently, however, the supplied build system might still work on those systems:

  • IBM Blue Gene/P
  • AIX-based clusters (Power6)
  • Cray XT, XE, XK series
  • Oracle/Sun Solaris/SPARC-based clusters

In addition, the provided configure options (see installation instructions) may provide a good basis for building and testing the toolset on other systems. Please report success/failure on other platforms to the Scalasca development team.
