2. HP NonStop System PlatformsHP NonStop System Platforms
◦ NonStop K-Series systems
 Last operating system release level was D48.03
◦ NonStop S-Series systems
 Current operating system release level is G06.2x
◦ Integrity NonStop and Integrity NonStop
BladeSystem
 Single-core processor based systems
(NSAA & NSVA):
 H-Series operating system thread – currently H06.nn
 Multi-core processor based systems (NSMA):
 J-Series operating system thread – currently J06.nn

3. TNS/E Hardware ArchitecturesTNS/E Hardware Architectures
◦ NonStop Advanced Architecture (NSAA)
 Multiple microprocessors in loose lockstep
for each logical processor
 HP Integrity NonStop NS14200 and NS 16200 Server
◦ NonStopValue Architecture (NSVA)
 Single-core microprocessor
for each logical processor
 HP Integrity NonStop NS1200 and NS2000 Server
◦ NonStop Multi-core Architecture (NSMA)
 Single, multiple core microprocessor
for each logical processor
 HP Integrity NonStop BladeSystem

4. Software LibrariesSoftware Libraries
◦ A library is a code file that provides functions
and data to other code files
◦ A code file that uses a function or data item
provided by a library is said to be that
library’s client
◦ Libraries can be:
 Linkable (static)
 Loadable (dynamic)
1 - TNS/E Overview 4

5. Dynamic LibrariesDynamic Libraries
◦ A DLL is an industry-standard type of
loadable library that:
 Provides functions and data needed by the program
and/or other loadable files
 Allows you to partition your applications into
functional units (DLLs)
◦ Dynamic
 Implicit DLLs (previously System Library)
 Public DLLs (previously SRLs)
 Ordinary DLLs
(only one accessible as User Library)

6. DLL AdvantagesDLL Advantages
DLLs offer many advantages:
◦ Programs can use many DLLs
◦ Additional libraries can be loaded after the
program starts
◦ Different processes can run with different
versions of a DLL
 Even running same program file

9. Execution ModesExecution Modes
◦ Interpreted TNS mode — TNS millicode
(Itanium instructions) emulating TNS
instructions and TNS data and stack layout on
User Data (UD) area and TNS register state
◦ Accelerated TNS mode — Itanium
instructions executing the equivalent of TNS
instruction and TNS data and stack layout on
UD area and TNS register state
◦ TNS/E mode — Itanium instructions using
native architecture and data layout and either
the MAIN or PRIV stack area
