I have a matlab script that I run from the terminal, that script creates an instance of another program using:



system('cd <path> && mpiexec -n 1 ./<program2> &')


Problem is I don't see any terminal output from program2. (It works if I omit the ampersand, but I need program2 to run in the background). Is it possible to have both the matlab script and program2 output to the same terminal?




terminal background-process io matlab

  • Hmm, it's not clear at all what MATLAB does if anything with the output from system('cmd&'); I suspect you'll need to find a different way to solve this problem.

  • Perhaps you can add >&/dev/tty to the mpiexec command to make it output to the terminal.

  • @meuh It didn't work. Still no output in terminal. Output works fine if I direct it to a logfile though... '.... ./<program2> > logfile 2>&1 &'

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
