Question

我已经用COMP Superscalar实现了一个应用程序，我的任务失败了。查看标准错误文件（job1_NEW.err）文件，我得到了一个File Not Found异常，但该文件存在于我的计算机中。

知道可能是什么错误吗？

编辑：添加了资源和项目文件

接口文件中的方法声明

@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 indeed a file you need to specify its type (i.e. type=Type.FILE). Otherwise the COMPSs runtime is not able to differentiate between a string variable and a file (because the file is actually a string with its path). 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
);

在COMPS中定义的任务中找不到文件
