Ð Low level network protocols Ð File & printer sharing

¥ Data

Ð Access to structured data

Ð Remote serving Ð Cross-platform development

¥ Management

Ð System & network resources

Data Interoperability Issues

¥ Business data kept in servers; used in desktop applications ¥ Data more than just text: multimedia, images, controls ¥ Apps must access & control data wherever it resides

slide-10
SLIDE 10

41st Cray User Group Conference Minneapolis, Minnesota

Distributed Object Issues

Big problems demand big solutions

¥ Complex client-server architectures

Ð Mix of UNIX & Windows NT clients & servers

¥ Instantiation of objects is bidirectional

Ð No one is in control; everyone is in control

¥ Existing standards must be supported

Ð Build on existing solutions

slide-11
SLIDE 11

41st Cray User Group Conference Minneapolis, Minnesota

Data Interoperability Standards

¥ ODBC: a standard database interface

  • wned by the SQL Access Group

¥ CORBA: a standard for building large distributed object systems; owned by the Object Management Group ¥ (D)COM: MicrosoftÕs standard for interfacing to objects, extended to support large distributed object applications

Application Availability

Applications can be run and controlled from the local system; execution may occur on that system

  • r on a remote application server
slide-15
SLIDE 15

41st Cray User Group Conference Minneapolis, Minnesota

Application Availability Issues

Remote access to interactive applications requires additional software Development and porting of applications is difficult, due to differences in computing models

slide-16

Application Development Issues

UNIX & NT are very different systems

¥ Hardware issues

Ð Basic data types Ð Bit & byte ordering Ð Data alignment/packing

¥ Software issues

Ð Pathnames & file system Ð Process & thread models Ð APIs & standards support

slide-22
SLIDE 22

41st Cray User Group Conference Minneapolis, Minnesota

Application Development & Portability

Three techniques for porting code

¥ Rewrite using targetÕs native APIs ¥ Use a porting library

Ð Local APIs ported to target system Ð Portable API set (e.g. Javaª)

¥ Emulation or binary translation

Is app serving a better answer?

Application Development Solutions

Porting packages reduce the effort

¥ Many issues handled automatically

Ð Pathname delimiters: / vs. \ Ð Line delimiters: <CR><LF> vs. <NL> Ð Universal naming: iris:/usr/tmp vs. \\pc\C:\progs\source

¥ Some still require manual intervention

Ð Compiler-generated symbols Ð Projects vs. Makefiles

á commondefs & commonrules

Points To Remember

¥ Interoperability isnÕt one big thing

Ð ItÕs a million small details

¥ Silicon Graphics knows the issues

Ð We grew up with heterogeneous networks

¥ WeÕre good at peaceful coexistence

Ð And weÕre determined to be even better
