Interactively Explore 120M Flight Records with GPUs

The demo is nice. The other thing is that a mapd server with 8 nvidia k40s for 3000 dollars each costs around 30000 (with CPU and main memory). For 30000 you can also buy a 4 socket server with a terabyte of main memory. Even though the GPUs can access their 300gb of memory much faster and have more cores, that won't help you because database workloads (filtering, grouping, joining) is not compute-intensive enough to give the GPU an advantage over CPU cores.

My bet is that a main memory database optimized for modern CPUs will do better on even larger datasets at the same server costs.

Has anyone actually been able to contact MapD? I've emailed, called, and left voicemails without any response. I'm not sure what is going on, but it's strange for a potential customer to have such difficulty getting in touch with sales.

The Aloha Airlines and Hawaiian Airlines data seems odd - thousands of negative delays?

Sounds like a fun dataset to play around with. I'll have to go look for it.

The whitepaper link doesn't work for me.

The demo is broken :/
