HP OpenVMS Version 8.4 for Integrity and Alpha servers SPD 82.35.19

• Full corporate implementation ensures OpenVMS

can share iCAP cores across hard partitions with HP-

UX on a common Integrity system.

• Integrated with Global Workload Manager (gWLM)

which can automatically reallocate active cores

across hard partitions in response to workload de-

mands.

Operational features:

• iCAP cores are purchased at a fraction of the price of

active cores and are denoted as Components With-

out Usage Rights (CWUR).

• Systems are conﬁgured at the factory before delivery

with a minimum of one active core and the required

number of iCAP cores.

• Once iCAP cores are activated, the balance of the

price is paid and an activation Rights To Use (RTU)

codeword is obtained from the HP iCAP web portal.

The iCAP core/memory is then made active by the

system manager.

• When a core or cell board is permanently activated,

support of the core/cell board is automatically added

to the overall support costs of the system.

Note: Activation of iCAP permanently adds a new core,

with all the attendant HP software and third-party soft-

ware licensing and support that this requires.

TiCAP (Temporary iCAP)

• Enables the customer to temporarily activate proces-

sors for a set period of time, with a minimum 30

minute granularity per core.

• Permanent activation fee is not required. You can

utilize an existing core for as long as needed.

• Accommodates customers with unpredictable or

planned temporary processor demands.

Operational features:

• Works with processors, does not include cell boards

or memory.

• Customer orders standard iCAP processors and

pays the same discounted price.

• Customer then purchases the right to temporarily ac-

tivate one or more iCAP cores for one or more 30-

CPU days.

• Does not require an email connection from customer

site to HP.

• The iCAP software issues a warning before the

TiCAP license is likely to expire, based on the rate

of depletion that it tracks across all relevant cores.

• Hardware services are included for the cores acti-

vated by the TiCAP license.

• The relevant operating environment (OE) is automat-

ically licensed on activated TiCAP cores.

Note: Other HP and third-party software have their own

licensing policies. HP recommends that customers pur-

chase sufﬁcient software licenses to meet peak needs.

OPERATING SYSTEM ENVIRONMENT

Processes and Scheduling

Executable images consist of system programs and

user programs that have been compiled and linked.

These images run in the context of a process on Open-

VMS systems. Sixty-four process priorities are recog-

nized on OpenVMS Alpha and OpenVMS for Integrity

servers. Priorities 0 to 15 are for time-sharing pro-

cesses and applications (four is the typical default for

timesharing processes). Priorities 16 to 63 on Alpha

and Integrity servers are for real-time processes. Real-

time processes can be assigned higher priorities to en-

sure that they receive processor time whenever they are

ready to execute.

OpenVMS uses paging and swapping to provide suf-

ﬁcient virtual memory for concurrently executing pro-

cesses. Paging and swapping is also provided for pro-

cesses whose memory requirements exceed available

physical memory.

64-Bit Virtual Addressing

The OpenVMS Alpha and OpenVMS for Integrity

servers operating systems provide support for 64-bit vir-

tual memory addressing. This capability makes the 8

TiB virtual address space available to the OpenVMS Al-

pha and OpenVMS for Integrity servers operating sys-

tems and to application programs. Future hardware im-

plementations for Integrity servers will provide greater

capacity. OpenVMS applications can take advantage of

64-bit processing by using 64-bit data types supported

by the compilers. For further details, see the SPDs for

the OpenVMS Alpha and OpenVMS for Integrity servers

compilers.

Very Large Memory (VLM) Features

OpenVMS Alpha and OpenVMS for Integrity servers

provide the following additional memory management

VLM features beyond those provided by 64-bit virtual

addressing. These features can be used by database

servers to keep large amounts of data in memory, result-

ing in dramatically increased runtime performance. The

VLM features provided by OpenVMS Alpha and Open-

VMS for Integrity servers are:

• Memory-resident global sections

• Fast I/O for global sections

• Shared page tables
