Subject: Re: [OMPI devel] Multiple Memory Pools
From: Ken Lloyd (kenneth.lloyd_at_[hidden])

We have identified a need in certain high performance applications to
specify memory sections -> L3 -> L2 - >L1 -> specific core -> specific
CPU -> specific machine. These tend toward hybridized CUDA apps where
other sections of the CPU are involved in non-CUDA (non-GPU) functions.
In our discussions, however, we haven't come across others who see the
same need. IOW, we are a very small market.
