Management host selection
To achieve the highest degree of performance and scalability, use a powerful management host.
LSF has no minimum CPU requirement. For the systems that LSF is supported on, any host with sufficient physical memory can run LSF as management host. Swap space is normally configured as twice the physical memory. LSF daemons in a cluster on Linux x86-64 use about 488 MB of memory when no jobs are running. Active jobs use most of the memory that LSF requires.
Note: If a Windows host must be installed as the management host, use only hosts with Windows 2008 R2
Server and Windows 2012 R2 Server as LSF management
hosts.
| Cluster size | Active jobs | Minimum required memory (typical) | Recommended server CPU (Intel, AMD, OpenPower, or equivalent) |
|---|---|---|---|
| Small (<100 hosts) | 1,000 | 1 GB (32 GB) | Any server CPU |
| 10,000 | 2 GB (32 GB) | Recent server CPU | |
| Medium (100 - 1000 hosts) | 10,000 | 4 GB (64 GB) | Multi-core CPU (2 cores) |
| 50,000 | 8 GB (64 GB) | Multi-core CPU (4 cores) | |
| Large (>1000 hosts) | 50,000 | 16 GB (128 GB) | Multi-core CPU (4 cores) |
| 500,000 | 32 GB (256 GB) | Multi-core CPU (8 cores) |
