+ | Look at this, the smallest Elastic Cloud Compute Instances are **g4dn.xlarge** yielding access to 4 vCPUs, 16GiB memory and 1x T4 GPU. The largest is **g4dn.16xlarge** yielding access to 64 vCPUs 256 GiB memory and 1x T4 GPUs. Now the smallest is priced at $0.526/hr, and running that card 24/7 for a year is a cost of $4,607.76 ... meaning ... option #7 below with 26 GPUs would cost you a whopping $119,802. Annually! That's the low tide water mark. | ||

+ | The high tide water mark? The largest instance is priced at $4.352 and would cost you near one million dollars to run per year if you matched option #7. | ||
+ | |||
+ | Rival cloud vendor Google also offers Nvidia T4 GPUs in its cloud; Google announced global availability back in April. Google Cloud’s T4 GPU availability includes three regions each in the U.S. and Asia and one each in South America and Europe. That page mentions a price of "as low as $0.29 per hour per GPU" which translates to $66K per year matching option #7 below. Still. Insane. | ||

We are embarking on expanding our GPU compute capacity. To that end we tested some of the new GPU models. During a recent users group meeting the desire was also expressed to enable our option to enter the deep learning (DL) field in the near future. We do not anticipate to run Gaussian on these GPUs so are flexible in the mixed precision mode models. The list of software, with rough usage estimates and precision modes, is; amber (single, 25%), lammps (mixed, 20%), gromacs (mixed, 50%) and python bio-sequencing models (mixed or double, < 5%). | We are embarking on expanding our GPU compute capacity.

Wes will provide 208V powered rack with 7K BTU cooling AC. Standard U42 rack (rails at 30", up to 37" usable). We also have plenty of shelves to simply hold the servers if needed. Rack contains two PDUs (24A) supplying 2x30 C13 outlets. [[https:// | Wes will provide 208V powered rack with 7K BTU cooling AC. Standard U42 rack (rails at 30", up to 37" usable).
