Setting Maximum Core Usage in ARM PL for LAPACK Functions

Weiwei Chen

If I want ARM PL LAPACK functions to support multi-core usage, are there any APIs, such as set_maximum_core or set_maximum_threads, that I can use?

    Hi Chris,

    Thank you for your response; I understand what you mean.

    I'm currently using ARM PL's EVD function on an embedded device, and I have a few questions:

    1. I'm unable to confirm whether this function (chbevd_) supports multi-threading and multi-core processing.
    2. I would like to explicitly set the maximum number of cores to achieve optimal performance. Your mention of "where we have implemented it, this selection will be available" seems a bit too much of a black box for developers.

    Thanks again for your response.
