Device Pool and Task Pool

v1.3.1: Instead of computing a kernel directly as

data00.nextParam(data01).compute(...);

operation can be saved for later as

ClTask task = data00.nextParam(data01).task(1, "test", testGlobalSize,testLocalSize);

with same parameters as compute() except number cruncher parameter. ClNumberCruncher instance is used only when computing a task as

task.compute(numberCruncher);

here, ClTask instance is an instance of parameter+kernel config frozen even if parameter fields are changed later. So multiple different tasks can be created from same parameters but with some of fields changed each time.

ClTask task = data00.nextParam(data01).task(1, "test", testGlobalSize,testLocalSize);
data01.read=false;
ClTask taskNoRead = data00.nextParam(data01).task(1, "test", testGlobalSize,testLocalSize);
data00.write=false;
ClTask taskNoReadWrite = data00.nextParam(data01).task(1, "test", testGlobalSize,testLocalSize);

task.compute(numCruncher);           // read+write both arrays
taskNoRead.compute(numCruncher);     // read only first array
taskNoReadWrite.compute(numCruncher);// write only second array and read only first array
