[DRMAA-WG] SGE resource elements

[Daniel Gruber]

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.
