Is this a good algorithm to implement it by C++/OpenCL?

In the main script:

1- define 4 string variables (read them from input file).

2- pass them to kernel.

---

In the Kernel (3000 threads)

1- read the 4 string variables.

2- do some math operations (SQRT, EXP, …) on the global id and put the result in the X double variable.

3- Insert this double variable between Strings.

4- generate txt file and put the stings and X in it.

5- call NGSPICE ROUTINE (it is a simulation tool and can be called by SYSTEM).

6- NGSPICE will output a file.

7- we need to read this file to find a number that we will consider it our Kernel output.

8- We have to compare all kernel outputs and get the Lowest one.

9- print the lowest number to txt file.

My questions are:

• did you think this Algorithm will give me a good results?
• Is it possible to do all these steps in kernel?
• Since I did not find a lot examples for deal with Strings by OpenCL could you please give me any related resources or examples.
