* VUE - vertex URB entry. An urb entry holding a vertex and usually

* MRF - message register file. Threads communicate (and terminate)
- * by sending messages. Message parameters are placed in contigous
+ * by sending messages. Message parameters are placed in contiguous
* MRF registers. All program output is via these messages. URB
* entries are populated by sending a message to the shared URB
