List of fields considered for compute accounting¶

Processors¶

The number of processors used or requested. A processor definition may be dependent on the machine
architecture. Typically processor is equivalent to the number of physical CPUs used. For example, if a
job uses two cluster “nodes”, each node having 16 CPUs each, the total number of processors would be
32.

Example

Comments:¶

Ralph: What about cores? Do we need to differentiate between cores and processors?

---

TimeDuration¶

This property identifies any additional measure of time duration associated with the
resource consumption. For example, it may report the connection time within a multitasking queue.

Example

Comments:¶

Ralph: How is it expressed what kind of time duration this property refers to? An attribute?
Jon: Wasn't it decided to use StartTime and EndTime instead of TimeDuration? Or is this wall time or CPU time?

---

TimeInstant¶

This property identifies any additionally identified discreet timestamp associated with the
resource consumption. For example, it may represent the time the job was queued, rather
than the start-time of the job.

Example

Comments:¶

Ralph: How is it expressed what kind of time this property refers to? An attribute?

ComputeUsageBlock¶

This is the block property of the compute usage fields. Similar blocks for storage and other resources should also be added.

Example

<ur:ComputeUsageBlock>
  <!—Compute Record properties go in here -->
</ur:ComputeUsageBlock>

Comments:¶

Ralph: ok

---

CpuDuration or ComputeDuration¶

CPU time used, summed over all processes in the job.

Example

Comments:¶

Ralph: ok

---

StartTime¶

The time at which the usage consumption (i.e. “job”) started. The value of this property
may depend on the selected queue system. For example, some systems include time to
stage files, others do not.

Example

Comments:¶

Ralph: ok

---

EndTime¶

The time at which the usage consumption (i.e. “job”) completed. The value of this
property may depend on the selected queue system. For example some systems include
time to stage files, others do not.

Example

Comments:¶

Ralph: ok

---

MachineName¶

A descriptive name of the machine on which the job ran. This may be a system hostname,
or may be a site’s name for a cluster of machines. The identification of the machine by
name may assume the context of the grid in which the machine participates; i.e. machine
names may be unique within a specific grid, but do not need to be unique across the set of
all grids.

Example

Comments:¶

Ralph: ok

---

NodeCount¶

Number of nodes used. A node definition may be dependent on the architecture, but
typically a node is a physical machine. For example a cluster of 16 physical machines
with each machine having one processor each is a 16 “node” machine, each with one
“processor”. A 16 processor SMP machine however, is 1 physical node (machine) with
16 processors.
