What is xlsmp in AIX?

I have istalled the Xlc compiler for AIX one of the library it installs is: /usr/lpp/xlsmp.rte/xlsmp.rte/3.1.0.6/liblpp.a. I am curious to know

What is xlsmp?

What does this library contain?

Solution

  • liblpp.a contains the installp packaging metadata for the fileset. Every AIX fileset (package) contains a liblpp.a with the fileset specific packaging information.

    The actual SMP runtime libraries are not shipped in xlsmp.rte, they are in the dependent fileset xlsmp.aix53.rte, and the paths of those libraries are:

    • /usr/lpp/xlsmp/aix53/libxlomp_ser.a
    • /usr/lpp/xlsmp/aix53/libxlsmp.a
    • /usr/lpp/xlsmp/aix53/libxlsmpdebug.a

    xlsmp is the IBM XL compiler's Shared-memory parallelism (SMP) runtime library/environment. Here's some reference pages from the Knowledge Center:
