linux - Saving GPU memory by bypassing GUI -


i have mac book pro 2 gb nvidia gpu. trying utilize gpu memory computations (python code). how saving may if bypassed gui interface , accessed machine through command line. want know if such thing save me amount of gpu memory?

the difference won't huge.

a gpu hosting console display typically have ~5-25 megabytes of memory reserved out of total memory size. on other hand, gpu hosting gui display (using nvidia gpu driver) might typically have ~50 megabytes or more reserved display use (this may vary based on size of display attached).

so can "estimate" of savings running nvidia-smi , looking @ difference between total , available memory gpu gui running. if is, example, 62mb, can "recover" around 40-50mb shutting off gui, example on linux switching runlevel 3.

i ran experiment on linux laptop quadro3000m happens have 2gb of memory. x display , nvidia gpu driver loaded, "used" memory 62mb out of 2047mb (reported nvidia-smi).

when switch runlevel 3 (x not started) memory usage dropped 4mb. means ~50mb additional available cuda.

a side benefit of shutting off gui might elimination of the display watchdog.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9,
