<br>
I am relatively new to Slurm and I am wondering whether it is possible <br>
to combine RAM between different nodes (e.g., can I combine three nodes <br>
with 384GB RAM each to run a job that requires 1TB RAM)? And if, could <br>
you please advise how to do so (I can't seem to find any documentation <br>
online)? Thank you!<br>
<br>
Best,<br>
