OK,

BTW is there some mailing list where should I subscribe to be aware of such changes in the future?

Best regards

Pavel

Hi,

I have a question about the hyperthreading. Previously when I wanted to
allocate full node with hyperthreading I did this:

#SBATCH --nodes=1
#SBATCH --cpus-per-task=1
#SBATCH --ntasks-per-core=2
#SBATCH --ntasks-per-node=96
#SBATCH --mem=180G

This no longer works, i.e., setting ntasks per node to anything higher
than 48 will show
sbatch: error: Batch job submission failed: Requested node
configuration is not available
even when the --ntasks-per-core=2 is set. Any ideas?
How can I allocate full node with hyperthreading?

Best regards
Pavel Ondračka
