There are two missing CPU features on c7g-2xlarge: paca
and pacg
You can check the list here
Together with #322, this is enough motivation to switch to using our own minimal archdetect
implementation rather than relying on archspec
for EESSI pilot 2023.06, I think...
@boegel There's an error in archdetect
that is fixed as part of https://github.com/EESSI/software-layer/pull/264
@laraPPr Can you check whether archdetect
correctly detects both neoverse_v1
and zen3
(cfr. #322), using:
EESSI_USE_ARCHDETECT=1 source /cvmfs/pilot.eessi-hpc.org/versions/2023.06/init/bash
Results on zen3
: https://github.com/EESSI/software-layer/issues/322#issuecomment-1702640074
[laraPPr@fair-mastodon-c7g-2xlarge-0001 ~]$ EESSI_USE_ARCHDETECT=1 source /cvmfs/pilot.eessi-hpc.org/versions/2023.06/init/bash
Found EESSI pilot repo @ /cvmfs/pilot.eessi-hpc.org/versions/2023.06!
2023-09-01 12:10:56 [INFO] cpupath: best match for host CPU: aarch64/arm/neoverse-v1
archdetect says aarch64/arm/neoverse-v1
Using aarch64/arm/neoverse-v1 as software subdirectory.
ERROR: EESSI software layer at /cvmfs/pilot.eessi-hpc.org/versions/2023.06/software/linux/aarch64/arm/neoverse-v1 not found!
The error is because archdetect
finds neoverse-v1
instead of neoverse_v1
This is also the case for neoverse_n1
which archdetect
recognizes as neoverse-n1
And there's the extra arm/
subdirectory which doesn't exist.
As part of #264, I've fixed the Arm detection and added an additional check in CI that ensures that whatever archdetect
spits out actually exists as an option.
When setting up the EESSI environment on the
neoverse_v1
nodes onaws/citc
archspec detectsneoverse_n1
instead ofneoverse_v1
.
