File not found in task specified in COMPS

Question

I implemented the application with COMP Superscalar, and I got an unsuccessful task. After looking at the standard error file file (job1_NEW.err), I got a File Not Found exception, but the file exists on my computer.

Any idea what could be a mistake?

EDIT: added resources and project files

Method declaration in interface file

 @Method(declaringClass = "matmul.files.MatmulImpl") void multiplyAccumulative( @Parameter(direction = Direction.INOUT) String file1, @Parameter() String file2, @Parameter() String file3, @Parameter() int bsize ); 

Answer 1

If your parameter is really a file, you need to specify its type (i.e. type=Type.FILE ). Otherwise, the COMPS runtime cannot distinguish between a string variable and a file (because the file is actually a string with its outline). Your interface should look like this:

 @Method(declaringClass = "matmul.files.MatmulImpl") void multiplyAccumulative( @Parameter(direction = Direction.INOUT, type = Type.FILE) String file1, @Parameter() String file2, @Parameter() String file3, @Parameter() int bsize );
