Unexpected memory limit?

[Ziv Lieberman]

Hi all,

I recently ran an inference in IQ-TREE which quickly failed due to an out of memory error. This seemed odd because while it was a large alignment with many partitions, I expect IQ-TREE to be able to handle these data, and I assigned up to 30 hours for inference.

When I look at the scheduler.conf output, it seems to show the issue:

nodes=1
node_exclusive=0
mem=11G
threads_per_process=6
runhours=30
subscribed=yes

By contrast, a successful unpartitioned inference of the same alignment had node_exclusive=1; mem=243G; threads_per_process=128.

Any ideas what went wrong here? The job ID is  NGBW-JOB-IQTREE_XSEDE-6DCBDFFF093D4A6C9C69CAC890BF0EEB (submitted under my advisor's account).

Thank you!
