Queue related resource elements and requests are (when available by OS): qname -> Queue names hostname -> Name of hosts notify -> Requests job notification for soft requests calendar -> Requests calender element min_cpu_interval -> Time between two automatic checkpoints in case of transparently checkpointing jobs. tmpdir -> Sets a TMP dir for DRM to a specific value. s_rt -> Soft request: Wall clock time h_rt -> Hard request: Wall clock time s_cpu -> Soft request: Combined CPU time consumed by all the processes in the job h_cpu -> Hard request: Combined CPU time consumed by all the processes in the job s_data -> Soft request: The maximum size of a process's heap in bytes. h_data -> Hard request: The maximum size of a process's heap in bytes. s_stack -> Soft request: The maximum size of a process's stack in bytes. h_stack -> Hard request: The maximum size of a process's stack in bytes. s_core -> Soft request: Maximum size of a core file in bytes. h_core -> Hard request: Maximum size of a core file in bytes. s_rss -> Soft request: Resident segment size h_rss -> Hard request: Resident segment size So SGE supports two types of requests: soft and hard. This could be a further classification of resource requests which differs from real resource usage reports. Host related resource elements and requests are: slots -> The amount of processes allowed to run s_vmem -> Only on OS with support for RLIMIT_VMEM: Soft request: Combined virtual memory of all processes. h_vmem -> Only on OS with support for RLIMIT_VMEM: Hard request: Combined virtual memory of all processes. s_fsize -> Soft request: The maximum size of a file in bytes that may be created by a process. s_fsize -> Hard request: The maximum size of a file in bytes that may be created by a process.
