3 Section [simulation]

This section is used to specify options when Haizea runs in simulation

This section is required when:

• Option mode (in section [general]) is set to simulated

1 Option clock

Valid values:

real, simulated

Required:

No (default is real)

Description:

Type of clock to use in simulation:

• simulated: A simulated clock that fastforwards through time. Can only use the tracefile request frontend

• real: A real clock is used, but simulated resources and enactment actions are used. Can only use the RPC request frontend.

2 Option starttime

Valid values:

An ISO timestamp: i.e., YYYY-MM-DD HH:MM:SS

Required:

Only if

• Option clock (in section [simulation]) is set to simulated

Description:

Time at which simulated clock will start.

3 Option resources

Valid values:

Any string

Required:

Yes

Description:

Simulated resources. This option can take two values, ``in-tracefile'' (which means that the description of the simulated site is in the tracefile) or a string specifying a site with homogeneous resources. The format is:

<numnodes> [ <resource_type>:<resource_quantity>]+

For example, ``4 CPU:100 Memory:1024'' describes a site with four nodes, each with one CPU and 1024 MB of memory.

4 Option imagetransfer-bandwidth

Valid values:

An integer number

Required:

Yes

Description:

Bandwidth (in Mbps) available for image transfers. This would correspond to the outbound network bandwidth of the node where the images are stored.

5 Option stop-when

Valid values:

all-leases-done, besteffort-submitted, besteffort-done

Required:

No (default is all-leases-done)

Description:

When using the simulated clock, this specifies when the simulation must end. Valid options are:

• all-leases-done: All requested leases have been completed and there are no queued/pending requests.

• besteffort-submitted: When all best-effort leases have been submitted.

• besteffort-done: When all best-effort leases have been completed.

6 Option status-message-interval

Valid values:

An integer number

Required:

No

Description:

If specified, the simulated clock will print a status message with some basic statistics. This is useful to keep track of long simulations. The interval is specified in minutes.
