I'm working on a problem that needs a huge array and the 128MB limit is really to small for me . I was wandering if this limit will be increased in the feature versions, or I can't rely on that.
You can play with environment variables to use more of your GPU's memory.
This will allow you to use 80% of your GPU's memory. I've noticed some speed degredation when setting this too high, but your milage may vary.
10x. I didn't know about GPU_MAX_ALLOC_SIZE
It worked for me. Now I can make allocations up to 204MB (from total 819MB). This is on windows 7 with 5970. With GTX 470, I can allocate I think something like 300MB.
I am not sure if the environment variable is documented somewhere. If such is the case, it might be for experimental purpose and cannot be guaranteed to be available in future.
Yep, but I guess no one will tell us what will be in future, so for developing purpose it's better than nothing...
GPU_MAX_HEAP_SIZE is documented here http://developer.amd.com/support/KnowledgeBase/Lists/KnowledgeBase/DispForm.aspx?ID=123
and GPU_MAX_ALLOC_SIZE AFAIK don't work anymore.
