... clock() returns the CPU time consumed by the program. So if the program is run in parallel the time returned by the function would be the accumulated of the time spent on all CPUs, rather than the time elapsed cplusplus.com/reference/ctime/cloc...

...or adb shell dumpsys | grep myapp | grep Error or anything that helps...etc if app is not running you will get nothing as result. When app is stoped messsage is shown on screen by android, process is still active and if you check via "ps" command or anything else, you will see process state is n...

...s in integer registers. You can still compile your code with a -mfpu=vfp, etc but you should use -mfloat-abi=softfp so that if the libc needs a float it is passed in a way the library understands. The Linux kernel can support emulation of the VFP instructions. Obviously, you are better off to com...

...nch prediction does work. Taken branches are problematic for instruction-fetch and decode even when they're predicted perfectly. Some CPUs statically predict branches that aren't in their history table, usually with assume not-taken for forward branches. Intel CPUs don't work that way: they don't...

...on is often to look at the flags register to check for overflow, sign bit, etc. If there's another add after that, it's very difficult to tell whether it's safe to begin execution of the 2nd add before the outcome of the 1st add is known. On a RISC architecture, the add instruction would specify th...

...same time" and thinking you can is just plain wrong. Depending on how many cpus you have, the load of the machine, the timing of many things happening on the computer will all have an influence on the time the threads/process start. Also, since the processes are started right after creation, the ove...
