+OpenCL, which is used for GPU applications, can also be used for multicore CPU applications.
+
+Depending on what drivers are installed on a client computer,
+one or more OpenCL implementations may be available.
+When you build OpenCL/CPU applications,
+they may be compatible with only one implementation,
+or there may be a preferred implementation.
+
+You can use the plan class mechanism to control what
+app versions are sent.
+Your app plan function can call
+{{{
+bool HOST::get_cpu_opencl_prop(const char* vendor, OPENCL_CPU_PROP&);
+}}}
+to see if the host has an OpenCL/CPU implementation
+for the given vendor ("nvidia", "amd", or "intel").
+If so, the OpenCL properties are returned.
+
+Use this function as follows:
+{{{
+bool app_plan_opencl_cpu_intel(SCHEDULER_REQUEST& sreq, HOST_USAGE& hu) {
+    OPENCL_CPU_PROP ocp;
+    if (sreq.host.get_cpu_opencl_prop("intel", ocp)) {
+        ... host has Intel OpenCL/CPU implementation
+    }
+    ...
+}
+}}}
