Ada:Usable Memory for Batch Jobs
Usable Memory for Batch Jobs
While nodes on Ada have 64GB, 192GB or 256GB of RAM, some of this memory is used to maintain the software and operating system of the node. In most cases, LSF will not schedule jobs if it cannot find a node to satisfy an excessive memory request.
The table below contains information regarding the approximate limits of Ada memory hardware and our suggestions on its use.
|64GB Nodes||256GB Nodes||192GB Nodes in v100 queue|
|Number of Cores||20 Cores (2 sockets x 10 core)||24|
|7600 MB |
|184000 MB |
LSF may queue your job for an excessive time (or indefinitely) if waiting for some particular nodes with sufficient memory to become free.
