look into the future

Ask me a

Yes/No

question.

ORNL Heterogeneous Distributed Computing Research

Look into the Future

Reply Hazy

Try Again

will tera scale systems be heterogeneous

As system

is updated

year to year

or you get

Multiple

clusters

ORNL Heterogeneous Distributed Computing Research

Will Tera-scale systems be Heterogeneous?

Yes,

Definitely

will pc clusters dominate hpc

In the

LOW END

ORNL Heterogeneous Distributed Computing Research

Will PC clusters Dominate HPC?

You May

Rely On It

will pc clusters make the top 5

Market isn’t

driving PC

node density

To level

needed by

Tera-scale

Cplant = ASCI Red

ORNL Heterogeneous Distributed Computing Research

Will PC clusters make the TOP “5”?

Cannot

Predict

Now

will linux emerge as the hpc os

Even though

Linux is not

an ideal

choice for

HPC

Desktop is

the driving

market

ORNL Heterogeneous Distributed Computing Research

Will Linux emerge as The HPC OS?

Signs

Point to

Yes

can i get reasonable of peak on my tera scale system

based on

ASCI results

so far

May as well

buy five 1TF

systems

than

one 5TF

system

ORNL Heterogeneous Distributed Computing Research

Can I get reasonable % of peak on my Tera-scale system?

Outlook

Not So Good

will the system stay up long enough

MTBF is

Shrinking

Rapidly w/

Large COTS

clusters

ORNL Heterogeneous Distributed Computing Research

Will the system stay up long enough

to complete

my simulation

Very Doubtful

will the system automatically recover my job

Scalable

Detection,

Notification,

and

recovery are

open

research

ORNL Heterogeneous Distributed Computing Research

Will the system automatically recover my job?

Don’t

Count On It

summary

You don’t

need a

Crystal ball

to see

the software

needs for

tera-scale

systems

ORNL Heterogeneous Distributed Computing Research

Summary

Application

runs slower than expected

system fails before it completes

and doesn’t recover the app.
