CloudFoundry Announces PaaS Certification Program

CloudFoundry has launched a certification program aimed at ensuring portability across various vendors with platform as a service (PaaS) offerings based on CloudFoundry code. Already, several cloud computing vendors, including

Find Compilation Time (in nanosecond, microsecond & millisecond) of any code (C, C++, JAVA & all others) & Execution Time of any Command

This is a C source code, written in gcc platform (Ubuntu, Linux). It finds the Compilation time of any Source code (like C, C++, Java & all others) as well as the Execution time of any command of Ubuntu in three time units, i.e nanosecond, microsecond & millisecond.  Note: Let I want to find compilation time of a Java source code using this C source code. Hence Java compiler must be installed in the machine. The following C source code: #include #include #include #include  int main(){   struct timespec ts1;   struct timespec ts2;   char str[20];    printf(” Compile the code/ Execute the Commamnd: “);   fgets(str, sizeof str, stdin);    clock_gettime(CLOCK_REALTIME, &ts1);   system (str);   clock_gettime(CLOCK_REALTIME, &ts2);    if (ts2.tv_nsec    {       ts2.tv_nsec= ts2.tv_nsec+ pow(10,9);            printf(” Compilation time: Nanosecond: %ld Microsecond: %ld Millisecond: %ld “, (ts2.tv_nsec – ts1.tv_nsec),  (ts2.tv_nsec – ts1.tv_nsec)/1000, (ts2.tv_nsec – ts1.tv_nsec)/1000000);   }   else      printf(” Compilation time: Nanosecond: %ld Microsecond: %ld Millisecond: %ld “, (ts2.tv_nsec – ts1.tv_nsec),  (ts2.tv_nsec – ts1.tv_nsec)/1000, (ts2.tv_nsec – ts1.tv_nsec)/1000000);    return 0;}
