OSX Fixes

Increase shared memory size:

sudo sysctl -w kern.sysv.shmmax=16777216000

sudo sysctl -w kern.sysv.shmall=4096000

and to allow a single process to connect to 32 shared memory segments:

sudo sysctl -w kern.sysv.shmseg = 32;

and the same for other properties

shmall and shmmax must be multiplicative by 4096

Run programs as sudo if they ask for shared memory

CUDA Timeout

This issue was happening on my ubuntu setup as well as the osx port I was trying to make. The issue has to deal with the graphics card being used as both the display driver and a computation device. There is a watchdog timer that prevents the gpu from running any single task for more than a few seconds. This setting is somewhere in the X settings. Only problem is, I cant find the file to change.

found the file, must find the the setting to change
