-Cerium Task Manager is parallel programming frame work.
-Generally, in order to demonstrate sufficient performance in GPGPU using Open CL, various tuning is needed.
+Cerium Task Manager is a parallel programming framework.
+To achieve good performance in GPGPU using Open CL, various tuning is needed.
 In particular, it is necessary to implement the dependency of task in Cerium by the function of Open CL.
-However, the flexibility of  framework will be spoiled if it specializes in Open CL. 
-Flexibility and the balance of performance is considered based on Sort, Word count, and FFT example.
+But, to match specialization for OpenCL spoiles of flexibility of framework. 
+Balance of flexibility and the performance is considered.
+We evaluate example  Sort, Word count, and FFT.
