IDL tip: compile gpuinit before running your own procedures

Another "gotcha" came up today from a user; when using GPULib in IDL, you may need to compile gpuinit before running your code. For example, to run a procedure you've written called foo, you should do something like the following:

IDL> .compile gpuinit
IDL> .compile foo
IDL> foo

As always, if you have questions or suggestion regarding GPULib, feel free to leave comments or email support@txcorp.com.
