Skylake warning message on Māui

I get the following warning message, do I need to worry?

craype-x86-skylake requires cce/8.6 or later, intel/15.1 or later, or gcc/6.1 or later

Short¶

No. This is only a warning message from an interim state. And gets resolved immidiately afterwards.

More details¶

Our software stacks are build with easybuild. There are toolchains defined, which wraps around the Cray PrgEnv-??? modules. These toolchains are called CrayIntel , CrayGNU or CrayCCE. Within the procedure of swapping the Programming environments all active PrgEnv get unloaded before loading the new on. In that meantime the module craype-x86-skylake stays loaded and realizes that there is no recent compiler version available. Immediately afterwards the new programming environment get loaded and therewith its compiler, which solve the issue.

You can check the actual situation by inspecting module list

There is a way to prevent the message: Assuming you want to load a certain toolchain or application. Let's say {code}VASP/5.4.4-CrayIntel-18.08{code} which is build with build Intel 18.08, we can first swap into the desired {code}PrgEnv{code}

module switch PrgEnv-cray PrgEnv-intel
module load VASP/5.4.4-CrayIntel-23.02-19

module unload craype-x86-skylake
module load CrayIntel        # or any other PrgEnv change you intended to  do
module load craype-x86-skylake
module load VASP/5.4.4-CrayIntel-23.02-19
