Just because of 256MB is 1/4 of my GPU memory...

You know you're pushing the boundaries when the development tools get scared..

GuardMalloc[ExampleApplication-42660]: If you really wanted to allocate so much memory, launch your executable with the environment variable MALLOC_PERMIT_INSANE_REQUESTS set to any value to circumvent this check.

GuardMalloc[ExampleApplication-42660]: Explicitly trapping into debugger!!!

GuardMalloc[ExampleApplication-42660]: Attempting excessively large memory allocation: 268435456 bytes

GuardMalloc[ExampleApplication-42660]: If you really wanted to allocate so much memory, launch your executable with the environment variable MALLOC_PERMIT_INSANE_REQUESTS set to any value to circumvent this check.

This isn't an error.. it doesn't stop anything working..

When someone wrote that tool they really didn't think you should be allocating 1/4 of the memory did they?

Then again when that bit was developed 256Mb may have been an insane amount. Times have moved on and now 256Mb can be small.

More fun is the MBP 2011 GPU cooling is borderline.. because image processing is almost infinitely parallel.. the GPU gets toasty! This version of the MBP has an issue with insufficient cooling.. may have to have a "slow it down a bit" button to maintain a temperature that won't cause a GPU crash due to temperature.

However… OSX 10.9 supports OpenCL on the Intel chips too.. so it'll work on the mac mini (although slower as it's using system ram).
