I have tested the latest commodity-priced GPU hardware from nvidia:<br>
<ul>
<li>GTX 580, 1.5 GB ram, 750MHz clock, 512 cores ($430 from
Newegg)</li>
<ul>
<li>factor 100 speedup in gen_3pi, current trunk release<br>
</li>
</ul>
<li>GTX 680, 2.0 GB ram, 1000MHz clock, 1536 cores ($495 from
Newegg)</li>
<ul>
<li>factor 150 speedup in gen_3pi, current trunk release<br>
</li>
</ul>
</ul>
<p>The current amptools code works without modification, but it
reports the wrong hardware information in the output log, in case
someone might care. A revision to GPUManager.cc that correctly
reports the features of the above hardware (sdkHelper.h is a
modified form of a header with the same name in the nividia SDK
release 4.1) is attached.<br>
</p>
<p>First release of the gen_5pi code for cuda amplitude generation
will be coming shortly.<br>
