Description:

The 0.82 are for the ATI cards that do not have OpenCL, ie HD3850. All others use the 1.0x releases.


I've updated 15 of the 16 different versions of the separation for all
systems. Post here if you have any problems (particularly if you have a
problem with the new 32 bit Linux GPU applications...)




New features:

-
 Faster CPU calculations because of SSE2 intrinsics from Crunch3r. This
should get a bit faster later when I get to some other stuff.



-
The binaries now include the different SSE levels for the critical
function (e.g. x87/SSE2/SSE3) all in one, and will use the appropriate
one for the detected CPU's capabilities, so you don't need any special
__sse2 version or anything. The problems on systems without SSE2 which
happened sometimes for the GPU applications should also be fixed.



-
 Checkpointing for GPUs for both OpenCL/Nvidia and ATI/AMD for CAL. It
will checkpoint no more frequently than after at least 10% progress, so
it might not checkpoint as frequently as your settings specify if you
have a particularly slow GPU. GPU checkpointing is a bit slow when it
does happen, so if you don't want it, you can disable it with the flag
--gpu-disable-checkpointing.



- The Nvidia OpenCL platform should now always be used avoiding issues if you had both AMD's and Nvidia's installed



-
 More reliable chunking for different GPUs. I didn't play with the time
estimates so much, but I think the actual run times should now be closer
 to the estimates. There should also be fewer cases where a GPU will end
 up using the slowest possible work size option. I'll probably have to
fiddle with this some more if people still aren't happy with the lag.



-
 Work around for a Catalyst driver problem where sometimes the GPU was
reported as 0 Mhz, resulting in much more lag which I think was some
peoples' problem.



- New flag that some people requested:
--process-priority (-b). On Windows this is 0 (lowest) - 4 (highest) for
 overriding the process priority. On Linux this is the nice value.



-
 CAL specific: Removed --responsiveness-factor flag. Use
--gpu-target-frequency or --non-responsive instead depending on what you
 want to do.



- Actually updated the 32-bit OS X application
