Seeing that we have clocked out more than 2^60.7 bits from A5/1 on ATI
hardware, I won't argue with that :-)

There is a real chance that this will happen driven by the need
to have plenty of disk accesses and the cheapest compute capable
GPUs or a modest CPU can handle the compute load for a single table.
But it is not high on the TODO list.
One could stitch a fast solution where clients monitor some URL for
lookup requests and report on findings in their table subset to some
cgi. 20 lines of perl.

Memory ECC is only available in fermi based teslas (C2xxx).
ATI is not absent in the HPC space, we are a part of it.

Also i trust 2 consumer grade cards working on
the same result more than 1 tesla. (Given the fact that a tesla
would need and error rate which is the square of the consumer grade cards
error rate)
The money you save in the shop can then pay your energy bill, but maybe
not the manpower to adapt the software to simultaneous computation.

There is no obvious way to add some form of checksumming to the algorithm.
The next best thing would be to compute every chain twice. Which is what
i do during testing (and also with 2 different algos, one on the GPU and
a reference on the CPU) and would be feasible if you cared for correctness.
But then again even with a 1% error rate you would not do this for the
rainbow tables, because the incorrect chains cannot lead to incorrect
results and would only waste some space and some time during lookup when
the lookup code works with them until they turn out not to produce
a result. Then you would produce 1.01% more chains and live happily ever
after.

One of the big advantages with Tesla is the use of registered memory for
the GPU. This significantly reduces the risk of a bad memory bit
screwing up your calculations, and the hardware can let you know if such
an error exists. ATI doesn't offer this feature on any of their boards,
and that is pretty much the reason for them being absent from the HPC
space, despite having better performance in relation to both price and
power.

If there was a miscalculation due to hardware, would you be able to detect

It's also not like you have miscalculations all over the place, given

[A51] USRP1 or USRP2

2010-07-26 Thread Murat Ozturk
Dear All,

Which one should I purchase? When I compare USRP1 has 4 ADC while USRP2 has
2 with better sampling rate. USRP2 provides Gigabit interface also.

 

However, which one can cover wider spectrum? How many channels can we listen
and dump simultaneously with USRP1 and USRP2?

Murat
