CPU

The CHARON-AXP CPU can be calibrated with "set ace" directive and the following parameters:

enabled

Parameter enabled

Type Boolean

Value

A CHARON-AXP emulated CPU is configured with the "enabled" command enabling the high performance Advanced CPU Emulation mode ("ACE"). The ACE option optimizes the HP Alpha instruction interpretation and significantly improves performance. It also requires approximately twice the amount of host memory allocated by CHARON instance itself to store the optimized code (Note that 2Gb of host memory + the amount of HP Alpha memory emulated per each CHARON instance is required).

ACE optimization is performed dynamically during execution. It does not need to write optimized code back to disk, ACE provides its full capability instantly. The optimization does not compromise the HP Alpha instruction decoding; CHARON-AXP remains fully HP Alpha hardware compatible and completely transparent to the HP Alpha operating systems and applications.

This configuration setting enables the ACE mode if the CHARON-AXP license permits it. If this configuration setting is omitted from the CHARON-AXP configuration file and the license permits it, "true" is the default, otherwise "false" is the default.

Example:

set ace enabled = false

Info
"`set ace enabled=true`" is ignored when the license does not permit ACE operation.

cpu_architecture

Parameter cpu_architecture

Type Text String

Value

Specifies the architecture of the virtual Alpha CPU. Can be one of the following: EV4, EV45, EV5, EV56, EV6, EV67, EV68

Example:

set ace cpu_architecture = EV6

Refer to 471924947 to find an appropriate value of the HP Alpha architecture per each HP Alpha model supported by CHARON-AXP.

cache_size

Parameter

cache_size

Type Value

Value

This parameter may affect Charon performance. Do not change this parameter until advised by Stromasys

"cache_size" defines the amount of memory in megabytes allocated to the ACE cache.

Default value is 1GB (1024 MB).

Example:

set ace cache_size = 2048

This parameter may be changed for performance optimization in case of some guest OS specific tasks (see the section below).

Div

class	pagebreak

num_translators

Parameter

num_translators

Type Value

Value

This parameter may affect Charon performance. Do not change this parameter until advised by Stromasys

"num_translators" defines the number of ACE translators.

Default value in most situations is number of I/O CPUs dedicated to CHARON (defined by "n_of_io_cpus" parameter) minus 1, but in some specific situations it may be set to some other value for better performance.

Example:

set ace num_translators = 4

host_options

Parameter

host_options

Type Text String

Value

This parameter may affect Charon performance. Do not change this parameter until advised by Stromasys.

"host_options" defines options of ACE (DIT) translator and code-generator. Those options affect Charon performance

Default settings are set to optimize performance for most guest OS (VMS and Tru64) usage profiles. However there are some profiles (for example OpenVMS compilation tasks) where the default settings do not provide optimal performance.

The following switches are available to user:

1. --fixed-variant=[X]

The value X can be one of three options: [-1, 0, 1]. This value defines the desired translation variant. Set -1 for dynamic (default) or 0 or 1 for the fixed number implemented by the translator.

2. --x64-optimize or --x64-nooptimize

This switch enables translation optimizations (the default is to optimize).

Default parameters have been changed in Charon version 4.9 compared to previous versions (4.8 and below). If Charon system demonstrates lower performance after upgrade to version 4.9, please test the system with host_options switched to default 4.8 settings:

set ace host_options = "--fixed-variant=0 --x64-nooptimize"

Note that in this case the parameter "471924947" must be set to the number of I/O CPUs dedicated to CHARON (see the "n_of_io_cpus" parameter). Also note that changing parameter "471924947" can be an alternative solution too (see the section below).

Enabling the old style performance optimization

Despite the fact that CHARON is already optimized for wide range of the guest OS tasks, there may be some situations (for example OpenVMS compilation tasks) when performance degradation may reach about 50% of the version 4.8.

In this case the following solutions can be applied:

Enlarging ACE cache size

Try this solution first. It is recommended to enlarge the ACE cache size at least in 2 times as it is shown in the following example:

...

If this solution does not work for the specific guest OS tasks, apply also the next solution.

TOY

CHARON-AXP maintains its time and date using the "toy" (time-of-year) component. In order to preserve the time and date while a virtual system is not running, the TOY component uses a binary file on the host system to store the date and time relevant data. The name of the file is specified by the “container” option of the "toy" component.

container

Parameter container

Type Text string

Value

Specifies a name for the file in which CHARON-AXP preserves the time and date during its “offline” period. This file also keeps some console parameters (such as the default boot device).

By default it is left unspecified.

Example:

set toy container="/Charon/my_virtual_system.dat"

It is recommended to specify the full path to the TOY file.

sync_to_host

Parameter sync_to_host

Type Text string

Value

Specifies whether and how the guest OS time is synchronized with the CHARON host time.

Syntax:

set TOY sync_to_host = "{as_vms | as_tru64 | as_is}"

where:

Parameter	Description
as_vms	If the guest OS is OpenVMS/AXP and its date and time must be set to the host's date and time each time it boots.
as_tru64	If the guest OS is Tru64 UNIX and its date and time must be set to the host's date and time each time it boots.
as_is	If the TOY date and time must be set to the host's UTC date and time.

Example:

set TOY sync_to_host = "as_vms"

To synchronize the guest OS with TOY, use the following commands (from "SYSTEM"/"root" account):

On OpenVMS/AXP On Tru64 UNIX

$ set time

# date -u `consvar -g date | cut -f 3 -d ' '`

The default value is "not specified" - it means that by default CHARON does not synchronize its guest OS time with the CHARON host time but collects date and time from the file specified with "container" parameter.

If "sync_to_host" parameter is specified there is no need to specify "container" parameter in addition.

ROM

The System Flash ROM file conserves specific parameters between reboots.

container

Parameter container

Type Text string

Value

Specifies the name of a file in which CHARON-AXP stores an intermediate state of its Flash ROM. This state includes, for example, most of the console parameters.

By default it is left unspecified.

it is recommended to specify the full path to this file

Example:

set rom container="/Charon/my_virtual_system.rom"

system_name

Parameter system_name

Type Text string

Value

Allows changing the system name, for example:

set rom system_name="Alpha Server 1000 4/200"

Refer to 471924947 to find an appropriate value of the HP Alpha system name per each HP Alpha model supported by CHARON-AXP

system_serial_number

Parameter system_serial_number

Type Text string

Value

Allows changing the system serial number, for example:

set rom system_serial_number = NY12345678

Any sequence of characters can be used as a serial number. Sequences longer than 16 symbols are truncated to 16 symbols.

Serial Numbers should be according to DEC standard: 10 characters. First two characters are capital letters, remaining 8 characters are decimal digits.

By default it is set to SN01234567

Div

dsrdb

Parameter dsrdb[n]

Type Numeric

Value

DSRDB - Dynamic System Recognition Data Block. These parameters allow changing the emulated hardware model type.

dsrdb[0] stands for SMM - System Marketing Model.

Example:

set rom dsrdb[0]=1090

471924947 describes connection between "dsrdb" parameter and the rest of the parameters defining an exact HP Alpha model - including SMM.

version

Parameter version

Type Text string

Value

Sets Console and PAL code versions in the following way:

Function Command

Set SRM Console version to X.Y-Z

set rom version[0] = x.y-z

Set OpenVMS PAL code version to X.Y-Z

set rom version[1] = x.y-z

Set Tru64 UNIX PAL code version to X.Y-Z

set rom version[2] = x.y-z

Example:

set rom version[0] = 7.3-1 version[1] = 1.98-104 version[2] = 1.92-105

Setting of a particular HP Alpha model

It is important to have the "system_name", "hw_model", "cpu_architecture" and "dsrdb[n]" (DSRDB - Dynamic System Recognition Data Block) parameters in sync. (see above for details) to configure CHARON-AXP for emulation of a particular HP Alpha model.

The following tables illustrate how to synchronize those values:
