hothardware BAM! NVIDIA And IBM Partner To Let GPUs Talk Directly To SSDs For A Major Performance Lift

If you're reading this, you probably don't need us to explain that CPUs are very good at doing one thing after another, while GPUs are very good at doing a whole lot of the same thing at once. They're radically different design paradigms, and a computer usually performs best, at least currently, when it has both working in tandem.

The thing is, despite their differences, the essential function of both is to take input data and compute on it for output. In a typical system, storage I/O is connected to the CPU and the GPU is treated as a co-processor or sub-processor; when the GPU needs data, it has to get it from the CPU first. That's not really a problem per se, except that in some modern systems the GPU is doing much more work than the CPU is. Ultimately, in that case, using the CPU to orchestrate everything collectively can reduce the performance of both processors.

How is this different than direct storage?

On the surface, It's not. Perhaps this is more a thing because its the server market ? Unsure.

The researchers were able to demonstrate BAM using a prototype system equipped with off-the-shelf GPUs and SSDs running Linux.

This is for Linux.  Directstorage is Windows only.
