process - Is there any limitations to number of running processes on host? -

-

in platform file have 1 host:

        <host id="worker1" speed="100mf" core="101"/>

then in worker.c create 101 (or > 100) processes expecting each on each core 1 process launched. noticed 100 first processes able execute task or write xbt_info:

int worker(int argc, char *argv[]) {     (int = 0; < 101; ++i) {         msg_process_create("x", slave, null, msg_host_self());     }     return 0; }  int slave(){     msg_task_execute(msg_task_create("kotok", 1e6, 0, null));     msg_process_kill(msg_process_self());     return 0; }

other processes above 100 first ones unable manage , kill:

[  1.000000] (0:maestro@) oops ! deadlock or code not clean. [  1.000000] (0:maestro@) 1 processes still running, waiting something. [  1.000000] (0:maestro@) legend of following listing: "process <pid> (<name>@<host>): <status>" [  1.000000] (0:maestro@) process 102 (x@worker1): waiting execution synchro 0x26484d0 (kotok) in state 2 finish

update here code functions are:

main

int main(int argc, char *argv[]) {   msg_init(&argc, argv);    msg_create_environment(argv[1]);          /** - load platform description */   msg_function_register("worker", worker);   msg_launch_application(argv[2]);          /** - deploy application */    msg_error_t res = msg_main();             /** - run simulation */    xbt_info("simulation time %g", msg_get_clock());    return res != msg_ok; }

deployment.xml

<?xml version='1.0'?> <!doctype platform system "http://simgrid.gforge.inria.fr/simgrid/simgrid.dtd"> <platform version="4">      <process host="worker1" function="worker">         <argument value="0"/>     </process>  </platform>

there internal limit size of maxmin system (the core of simgrid), 100, , may hit in case. added flag make limit configurable. pull last version, , try setting maxmin/concurrency_limit 1000 , see if fixes issue?

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
