Does anyone know any details of REX computings' approach ?

Their website seems to indicate they have some sort of elaborate plan for profile-guided optimisations ..

I can imagine having multiple versions of similar high-order-functions for parallelism (things like par_foreach managing DMA for you) and/or some template parameters, allowing you to tweak your implementation but it sounds like they plan to absorb some of this complexity into a compiler, which could be cleaner, if it works.

How far could this go. Imagine something to automatically break large loop bodies up into pipeline stages (a pipelined par_foreach would be an easy way to leverage a lot of cores..)

I am on Windows 7, and when I run PyCharm, I cannot copy and paste into and out of it. Worse, I cant even copy files using explorer.

To make thing worst, I cannot paste anything even after closing PyCharm. The only way to fix it, apparently, is to reboot my machine.

Does anyone experience this?
