+ISPC
+----
+
+`ISPC <http://ispc.github.io/>`_ is a C-based language based on the SPMD
+(single program, multiple data) programming model that generates efficient
+SIMD code for modern processors without the need for complex analysis and
+autovectorization. The language exploits the concept of “varying” data types,
+which ensure vector-friendly data layout, explicit vectorization and compact
+representation of the program. The project uses the LLVM infrastructure for
+optimization and code generation.
