I sent you a PM about the warning that gets issued (clFFT resources not freed) if a GPU task gets suspended - eg. if the multiplicity of concurrent tasks gets reduced and as a result a task gets suspended.

For more background about why I sent the PM, you can check this message, and the messages that led up to it.  The warning was in the stderr.txt output and I wasn't sure if it was important or not.

Thanks for the new test app.  I guess cecht will be interested to see if it performs any differently when his script is reducing task multiplicity :-).  Is there expected to be any benefit (reduced memory consumption) for running multiple tasks under conditions where multiplicity is being changed like this?

Cheers,
Gary.

I'm receiving that only for AMD cards (for about 10 hours now). My Nvidia cards still get only 2.07.

Thanks for reporting. Indeed there was something wrong on the server side. Should be fixed.

So far as I can tell, 2.09 is running tasks with the same memory usage as 2.08. My fancy little script-in-development hasn't yet been put to the test to resolve excessive GPU memory use because the Spotlight tasks to date have had relatively light memory requirements. Wouldn't it be wonderful if Bernd's new app rendered obsolete my fancy little script?  :-\ 

Ideas are not fixed, nor should they be; we live in model-dependent reality.
