And only AFTER i posted that behind each trading machine in the  
datacenter of exchanges and platforms
there is an entire analysis department with huge HPC clusters.

Then 30 minutes later you post Royal Bank of Scotland, which was kind  
of bankrupt
because they did do so bad, that they have got 10k servers doing the  
analysis.

Had you known this *before* doing the silly post which breathes that  
you see HFT as a business that has nearly
nothing to do with HPC, you would've realized that
not seldom most nations in Europe have just 1 HPC center that  
government operates,
and hundreds of HPC centers operated by traders.

They are an ever growing force in the HPC.

The larger HFT in terms of infrastructure has got  a larger HPC  
infrastructure than goverment has in terms of crunching power.
Each single one of them.

That makes them a rather large market for HPC to take a look at and  
take them serious. With each exchange slowly moving
from slowish gigabit ethernet with round trip processing time in the  
many milliseconds, the amount of datapoints a second will
dramatically increase during surges. That will have a dramatic impact  
on the crunching power they need and with those
bandwidths it's 100% HPC what they do back in their analysis department.

Now how they do their calculations, there is a as many solutions to  
that as there are traders, so there is not a sensible
word to say about it, except that they use lots of hardware and we  
definitely can see this as HPC type calculations,
whether you like it or not.

Why do i keep getting the impression you don't know the difference  
between a trader and a bank?

Can you find for me of one of the larger High Frequency trading  
hedgefund in the USA, which is called Renaissance Technologies,
their OFFICIAL homepage and then explain to me what infrastructure  
they got?

If they're totally open i bet they like to tell on their homepage  
what hardware they got?

That's just 1 out of the thousands.

Actually nowadays they have a homepage. www.rentec.com :)

Thanks,
Vincent
