-We do not do AI (yet).  The GPU usage pattern is mostly one job per GPU for exclusive access.  So no NVlink requirements, CPI connections sufficient.  The application list is Amber, Gromacs, Lammps and some python biosequencing packages. Our current per GPU memory footprint is 8 GB which seems sufficient.+We do not do AI (yet).  Our GPU usage pattern is mostly one job per GPU for exclusive access.  So no NVlink requirements, CPI connections sufficient.  The application list is Amber, Gromacs, Lammps and some python biosequencing packages.

-A lot of information comes from this web site [[https://blog.exxactcorp.com/whats-the-best-gpu-for-deep-learning-rtx-2080-ti-vs-titan-rtx-vs-rtx-8000-vs-rtx-6000/|Best GPU for deep learning]]+A lot of information comes from this web site [[https://blog.exxactcorp.com/whats-the-best-gpu-for-deep-learning-rtx-2080-ti-vs-titan-rtx-vs-rtx-8000-vs-rtx-6000/|Best GPU for deep learning]].  Deep learning (training and inference) are driving the GPU models more towards single precision (FP32) or even half precision (FP16) to speed up training. Double precision models (the P100 and V100) are still available but there is a scientific drive towards mixed precision applications (FP64/FP32 or FP32/FP16 or even integer mixes).

-Learn more about the T4 ... the T4 can run in mixed mode (fp32/fp16) and can deliver 65 Tflops. Other modes are INT8 at 130 Tops and INT4 260 Tops. Now at 65 Tflops mixed precision the cost dives to $34/tflop. Amazing. And the wattage is amazing too.+Learn more about the T4 ... the T4 can run in mixed mode (fp32/fp16) and can deliver 65 Tflops.
