[quote]Both of my ATI equipped macs (old iMac & new Mac Pro) are erroring out on all GFN GPU tasks :-(

Is your other GPU double precision? The error message you're getting is "no GPU". I think you'll get that error if there's no double precision GPU available.

As a side note, it seems we have a problem with Linux and Mac builds. When an error like this is detected, it's supposed to wait an hour before reporting the error. That prevents a single computer from trashing thousands of tasks. The delay seems to be broken. We'll fix that part.

But there's nothing we can do about it not running on Single Precision GPUs. Right now, it won't work on FirePro either, but it's unclear whether that can be fixed.

GFN262144: INFO: Test for 1100680^262144+1 was ignored. Your application and/or prpclient is obsolete and MUST be upgraded

Are you running an old version of PRPNet or Genefer? Or is something broken?

There are also several other PG users ahead of me in the race for that dubious distinction.

I believe that to run that series card with OpenCL apps you will need to run a catalyst driver somewhere in the 11.7 to 11.10 range (It has been a long time since I crunched with my HD4670, so anyone please correct me if I am wrong on this range).

But SSE2 could be the problem. The old AMD processor did not support SSE2, only SSE. I must check if there's even a sse2 processor for socket 462 boards available.
