Usable Memory for Batch Jobs

While nodes on Curie have 256GB of RAM, some of this memory is used to maintain the software and operating system of the node. In most cases, excessive memory requests will be automatically rejected by LSF.

The table below contains information regarding the approximate limits of Ada memory hardware and our suggestions on its use.

Memory Limits of Nodes
Node Count 48
Number of Cores 16 (2 Sockets x 8 Cores)
Memory Limit
Per Core
14300 MB
14 GB
Memory Limit
Per Node
239000 MB
234 GB

LSF may queue your job for an excessive time (or indefinitely) if waiting for some particular nodes with sufficient memory to become free.
