c++ - How to make an OS CPU/Process Scheduler -


here assignment: in subproject charged design , implement ready queue (rq) support scheduler subsystem of os. rq must designed ‘priority’ queue, governed fifo policy. write scheduler class manage queue – scheduling processes queue. assume queue length unknown start when computer system booted, or turned on. processes enqueued , dequeued depending on assigned priority numbers, randomly generated. priority order of queue preserved. processes executed on virtual cpu (object) random-execution time when dequeued scheduler rq. write cpu class has 1 member function, ‘execute,’ gets called execute process. write process class generates ‘processes’ @ random time intervals, , calls scheduler object enqueue processes. entire logic of virtual cpu’s ‘execute’ function set time-counter each process random-execution time when dequeued/called scheduler object. balance number of processes-generated , processes-executed using poisson/exponential distribution functions (as generate random numbers). times generate process arrivals , scheduling mutual exclusive, , random.

test ‘simulator’ 1000 runs.

essentially need make linked list (the ready queue) , 3 classes...1 class scheduler add "processes" rq, 2 class cpu "execute" process on rq , 3rd class called processor creates "processes"

i'm lost in fact, i'm not sure "processes" i'm supposed create are, , how classes interact each other. apprieciated.

c# - Update a combobox from a presenter (MVP) -

i using mvp in project, new in mvp. have 2 comboboxes. when select option in combobox, combobox should filled new data. this action in presenter. view 'view1' in presenter, , introduced combobox1 , combobox2 properties in 'view1', because need 'datasource', 'displaymember', 'valuemember' , 'refresh()' in method below. but, when using pattern, enough send property like public string combobox2 { { return combobox1.selectedvalue.tosstring(); } } into presenter not whole combobox. how can solve problem? public void onselectedindexchangedcombobox1() { if (view1.combobox1.selectedindex == -1) { return; } datatable dt = tools.getdatatable("a path"); var query = (from o in dt.asenumerable() o.field<string>("afield") == farmerview.combobox1.selectedvalue.tostring() orderby o.field<string>("anotherfield") select...

How to understand 2 main() functions after using uftrace to profile the C++ program? -

i trying uftrace profile following simple c++ program: #include <iostream> class { public: a() {std::cout << "a created" << std::endl;} ~a() {std::cout << "a destroyed" << std::endl;} }; int main() { a; return 0; } the profile result this: # uftrace a.out created destroyed # duration tid function 2.026 [ 4828] | __cxa_atexit(); [ 4828] | main() { [ 4828] | __static_initialization_and_destruction_0() { 89.397 [ 4828] | std::ios_base::init::init(); 0.768 [ 4828] | __cxa_atexit(); 93.029 [ 4828] | } /* __static_initialization_and_destruction_0 */ 94.425 [ 4828] | } /* main */ [ 4828] | main() { [ 4828] | a::a() { 11.104 [ 4828] | std::operator <<(); 10.825 [ 4828] | std::basic_ostream::operator <<(); 24.514 [ 4828] | } /* a::a */ [ 4828] | a::~a() { 0.978 [ 4828] | ...
