Using the GPU on an Azure NVIDIA enabled virtual machine

GPU-accelerated computing is the employment of a graphics processing unit (GPU), along with a computer processing unit (CPU), to facilitate processing-intensive operations such as analytics, machine learning, and engineering applications.  It is becoming much more popular due to the larger number of applications where it can be used: Artificial Intelligence (AI) being one example. Azure [...]

Are Power Settings Holding Back Your Virtual Machines?

Physical servers continue to increase in processor socket and core count. This increase in resources has been a boon for performance, but it’s come at the expense of larger power draw. To reduce power consumption, many vendors have implemented power savings settings at the hardware level by controlling the processor P-States. As you may have [...]
