Now 38 years

this is basically counting back to my diploma thesis where I developed my

first performance tools in 1987.

I just realized by discussions this morning I should have slightly made a slight modification

to the title.

It should be Memories of a Parallel Performance Engineer.

I always was interested in how to optimize communication

synchronization

parallelism

and not so much the more node level single core performance things where the experts

sitting here in Erlangen.

So that we are kind of nicely match each other

you experience and our experience on the other

side.

Okay

I basically made this talk historically so people at least in the room should recognize

the picture.

So it's the Meanwhile Handler Tower

I think it's called in English.

So it's the Institute for Informatics in Erlangen and I've been there like

you know

basically

I've been there 82, starting my computer science there but working on parallel tools was with

my diploma series in 87.

And the context was at that time there was a Sonderforschungsbereich 182

multiprocessor

and network configurations

like multiprocessor network configurations

went over 12 years

in four times three phases and I was part of it in the first two phases.

So with people who are non-chairmen

so Sonderforschungsbereich is like a large grant given to a university.

I think in our case it was over 30 PhD people working on different aspects from like operating

system all the way up and as I said it's early 80s and it was like really very early time

for a university to think about parallelism

parallel computers and so on.

And I personally was part of Work Package C1

Messung

Modellierung

Bewertung von multiprocessor

Rechnernetzen

like measurement

modelling and evaluation of processes and networks.

And there's a lot of parallel system development so I encourage you to come here and there's

actually still

these machines are partially visible here and you can see them.

So ECBA

which was the first parallel system already in the 60s or 70s and then DIRMU and

MEMSY in the 80s, early 90s or something.

Another thing you will see is
