The cloud dispatch service can run on any node that can connect to the Arvados API service, the cloud provider's API, and the SSH service on cloud VMs. It is not resource-intensive, so you can run it on the API server node.
+More detail about the internal operation of the dispatcher can be found in the "architecture section":{{site.baseurl}}/architecture/dispatchcloud.html.

+h4. NVIDIA GPU support
+
+To specify instance types with NVIDIA GPUs, you must include an additional @CUDA@ section:
+
+<notextile>
+<pre><code> InstanceTypes:
+ g4dn:
+ ProviderType: g4dn.xlarge
+ VCPUs: 4
+ RAM: 16GiB
+ IncludedScratch: 125GB
+ Price: 0.56
+ CUDA:
+ DriverVersion: "11.4"
+ HardwareCapability: "7.5"
+ DeviceCount: 1
+</code></pre>
+</notextile>
+
+The @DriverVersion@ is the version of the CUDA toolkit installed in your compute image (in X.Y format, do not include the patchlevel). The @HardwareCapability@ is the CUDA compute capability of the GPUs available for this instance type. The @DeviceCount@ is the number of GPU cores available for this instance type.

+Azure recommends using managed images. If you plan to start more than 20 VMs simultaneously, Azure recommends using a shared image gallery instead to avoid slowdowns and timeouts during the creation of the VMs.
