Scalasca 2.x series

This software is free but copyrighted

By downloading and using this software you automatically agree to comply with the regulations as described in the Scalasca v2 license agreement.

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.

Sneak peek
Development tarballs		Recent CI-approved development builds straight from our source-code repository (with limited support).

Note that neither Score-P nor the Cube GUI are included in the Scalasca distribution tarball but have to be downloaded and installed separately. See the build requirements page for download links.

Supported Platforms

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

• IBM BladeCenter & iDataPlex clusters
• Cray XC series
• various Linux-based clusters (x86_64, Power8, armhf, AArch64)

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

• IBM Blue Gene/Q
• IBM Blue Gene/P
• AIX-based clusters (Power6)
• Cray XT, XE, XK series
• Fujitsu FX10, FX100, and K computer
• Intel Xeon Phi (KNC/KNL)
• 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.
