GPGPU as many potentiality on many tasks (not every), especially handling matrices as with a database, a minimum of according all of the PR all around the subject.
Still I've not found a database which use GPGPU to accelerate performance.
Are you aware any free database that exploit GPGPU? Why GPGPU is really slow to consider a hold in marketplaces where it might be this type of major improvement?
Here's some research that's been completed in that area. That being stated, the restricting element in many database configurations is disk speed. Most databases are extremely huge they ought to be saved on disks (unless of course you're Google or Facebook and may afford terabytes of RAM). This limits the rate where results could be came back because more often than not is spent seeking around the hard disk, rather than doing computations around the CPU.
