![]() then i added another VM and now i cannot add it to my cluster. i setup using the official openHPC guide and it worked (tests successful).

VipuIpuofDir: Path to shared storage location writable by scheduler, and readable by all nodes and user accounts. In addition, nf should contain the following configuration to allow sharing IPUoF configuration files UseReconfigPartition: Set to 1 to specify that reconfigurable partitions should be created. The default value is 50.įorceDeletePartition: Set to 1 to specify forced deletion of partition in case of failures. Default value is 256.ĪpiTimeout: Timeout in seconds for the V-IPU client. MaxIpusPerJob: Maximum IPUs allowed per job. IpuofDir: The directory where IPUoF configuration files for user jobs will be stored. The following configuration options are supported:ĪpiHost: The host name or IP address for the V-IPU controller.ĪpiPort: The port number for the V-IPU controller. For instance, a GRES model,``pod1``, needs a corresponding configuration file named as nf For the additional GRES models, configuration files are named with the desired Moreover, administrators can configure additional GRES models for the V-IPU representingĭifferent V-IPU clusters. Configuration parameters Ĭonfiguration parameters for the V-IPU resource selection plugin are set in separate configurationįiles that need to be stored in the same directory as nf.
