New software stack “2020b” is available on the cluster

Posted by on Monday, September 27, 2021 in Website.

The new software stack 2020b is available on the ACCRE cluster. It includes the following features:

  • GCC version 10.2
  • New Intel compiler and MKL libraries etc. released in 2020
  • R 4.0.5
  • Python 3.8.6 and Python 2.7.18
  • SciPy-bundle/2020.11 (which includes the newer version of numpy)
  • etc.

The 2020b software stack is built based on the GCC 10.2 compiler. Since the Intel based software stack is seldom used by users this 2020b stack is the last Intel compiler based software stack ACCRE will provide. However if you need help on using the Intel compiler suite to build your software, or if you want to have an Intel compiled software which we provided through the 2020b software stack, please create a ticket in the helpdesk to let us know.

To solve the compatibility issues especially for the R user community, we dropped the default arch-dependent compiling options. This will enable the compiled software portable between different compute nodes. For example, we expect the software from 2020b stack could be used for the zen and zen2 machines (with AMD EPYC processors). If you still experience compatibility issues using the software from 2020b stack please open a ticket and let us know.

We are planning to add more software to the stack. Following our current software policy, we will add the most commonly used software to the new software stack. If you want to add software to the new stack please create a ticket using the Software Installation Inquiries form. We will discuss your software proposal in our meeting.

If you have any further questions in using the new software stack, please create a helpdesk ticket.

Updated 9/28 to clarify that an Intel based software stack is available for 2020b, but will be discontinued for future ACCRE software stacks.
