Intel Compiler 2020 with old processors

[Tommy]

We are working with a computer cluster with old Intel XEON E5-2670 v2 processors, CentOS 6 and Intel Cluster Studio XE 2014. We are planning to update the OS to CentOS8 and keep the processors for at least one more year.
Does it make any sense to update the Intel Cluster Studio XE version to the new release (2020) with regard to calculation performance? Would the new compiler improve the peformence of the old processores  noticeable compared to the 2014 version?

Hi,

Looks like your hardware configuration is pretty old. The latest 2020 version might not be compatible with your hardware.

Kindly refer to the release notes of Parallel studio XE 2020: https://software.intel.com/content/www/us/en/develop/articles/intel-parallel-studio-xe-release-notes-and-new-features.html

Check the hardware/software requirements for Parallel studio XE 2020.

Parallel studio 2014 version is not supported anymore as per this link: https://software.intel.com/content/www/us/en/develop/articles/intel-parallel-studio-xe-supported-and-unsupported-product-versions.html

Hi Rahul,

thanks for the reply and the link. Parallel studio XE 2020 is recommended for E5 v5 or newer. So it's not an option for us to update.

Instead, I think we should seriosly think about new hardware.

Thanks for your help!

Intel Compilers will generate code for Ivy Bridge

Use -xIVYBRIDGE or -xAVX (or equivalent switches for Windows).

If you move to CentOS 8, then I would suggest to upgrade to PSXE2020 because your 2014 version no longer supports. Plus, we always improve performance at default with newer compiler version compare to the older ones.
