platform to run against gtx 280 graphics card, the performance improvement
might be increased 10x to 100 x faster. I have not done that code writing
for this test. But if someone on this dug list willing to pay me to write
a c in cuda code, I am willing to try. ;-)</span><o:p></o:p></p>

plain memory mode, and most other C#, java adds some extra work load. To run
against cuda code, Delphi losing on memory access latency compare to gpu vast
memory bandwidth in the card. The more data volume size will show cuda will be
better than any cpu memory latency restricted code.</span><o:p></o:p></p>

Hald and others recently did a benchmark of a certain algorithm to figure out,
which was fastest. It evolved into a kind of competition to make the fastest algorithm
to solve this problem:Fill a data structure with 1,000,000 random, unsorted
values from 0-100 Run through this data structure 200 times, counting a) number
of values = 42 b) average for all 1,000,000*200 valuesThe benchmark was run on
a new T5800 Toshiba laptop running 32-bit Windows Vista. Nothing had been done
to the Vista to make it faster or behave in a special way.The results were
interesting, and our conclusions were:</span> <o:p></o:p></p>
