I mean, really really shiny.

Who the heck are those guys (and where are they)?

A Brief Intro

• Born and raised in NJ
• Graduated University of Illinois,
  Urbana-Champaign, 2002
• Worked for HP ever since
• Spent worst year of my life in Dallas, TX
• Now living in Ft. Collins
• Met John at GunksFest 2000

Outline

• Itanium aka IA64 aka IPF (but not Itanic!)
• Rage an offline hardware diagnostic
• HP-UX (but only if you want)
• When to sleep in class
• (and when to pay attention)
• Surviving at MEGAGLOBALHYPERCORP
• Continuing education
• Q A
• we can go as deep or broad as you want let me
  know (ie, I hate boring, irrelevant talks and so
  should you!)

IA-64 Principles
(I stole this slide)

• Explicitly parallel
• Instruction level parallelism (ILP) in machine
  code
• Compiler schedules across a wider scope
• Enhanced ILP
• Predication, Speculation, Software pipelining,
  ...
• Fully compatible
• Across all IA-64 family members
• IA-32 in hardware and PA-RISC through instruction
  mapping
• Inherently scalable
• Massively resourced
• Many registers
• Many functional units

HP Integrity Servers

• From single CPU up to 256 CPUs, 2 TB of memory
• nPars give electrical isolation
• vPars allow multiple OS instances
• Run 4 OSes at the same time, in the same box
• Reliability, Availability, Scalability (RAS)

13
Rage

• Based on Linux, instrumented for error detection
• Very small OS footprint (10 MB) boots very
  quickly ( 5 min.)
• Ideal for transient latent hardware problems

• User friendly interface, produces easy to
  interpret errors
• Implements a totally independent error monitor,
  persists even when OS hangs or HW faults
• Same Hardware exercisers for HP-UX, Linux,
  Windows OpenVMS servers

Alexs College Cliffs Notes

• Classes to care about
• Writing
• Data Structures
• Computer Architecture
• Operating System design
• Leadership development
• Writing, writing, writing

16
Data structures that count

• Arrays and linked lists
• Queues and stacks
• Hashes (does not apply to C)
• Thats it.
• Learn about trees, skiplists, graphs
• and forget them as quick as you can
• Understand what running time implies (big-O)
• but youll never need to calculate them
  post-college

17
Computer Architecture and OS Design

• CPU architecture
• cache hierarchy
• pipelines and all their implications
• Virtual memory
• TLBs, page tables
• Everything else

18
Writing, leadership, and more writing

• Good writing shows clarity of thought
• Learn enough grammar to be correct
• but not enough to be annoying
• Unintelligible, muddy writing is worthless
• Practice, practice, practice
• Leadership courses teach you how to influence
  others with a high level of emotional
  intelligence

Plastics?

Quickie interviewing tips

• Clean up your resume
• Think out loud
• Learn what a pointer is
• reverse a string. now do it in place.
• add a node to a linked list. now delete it.
• Show some enthusiasm!

For some reason most people seem to be born
without the part of the brain that understands
pointers. Joel Spolsky

PC Load Letter?!??!!!

Life in the Matrix

• Managing your manager
• Live in the whitespace
• Effective networking
• Work/Life balance
• Own your career
• Dealing with BS

23
Relevancy and you

• Always keep your resume current
• Program for fun (and ship it!)
• Volunteer with interns
• Mentor a student
• Speak at seminars
