Intel: My 10nm Process is Denser Than Yours

Process technology is important as the lower the process node, the more efficient the processor becomes, which leads to either longer battery life for the same tasks on battery powered devices, or allows for higher frequencies extracting more performance. Qualcomm and Samsung recently announced Snapdragon 835 SoC was manufactured using 10nm process technology, but Mark Bohr, an Intel Senior Fellow and director of process architecture and integration at Intel Corporation. wrote a blog post explaining that while in the past process node size and density were progressing in a “linear” fashion, this is not the case anymore, as marketing has changed, and some companies advance node names, even in cases where there’s minimal or no density increase. The chart above implies that some companies 10nm process is barely better than Intel’s 14 nm process, with their 10nm process capable of integrating about twice as much transistors per square millimeter compare to competitors’ 10nm process. Mark goes on to say a …

How to check open files for a process

While debugging your program, you may encounter the message “Too many open files”. One way to fix the issue could be to review your code and check open, fopen, socket and pipe calls are matched with close and fclose calls, but with large projects this may be cumbersome. A better way is to list the open files using the proc filesystem. I’ll use VirtualBox program as an example since this is running in our server. First, locate the process ID (PID): pgrep VirtualBox 3901 3950 Then list the file descriptor opened for process 3901 sudo ls -l /proc/3901/fd total 0 lrwx—— 1 root root 64 2010-10-05 14:52 0 -> /dev/pts/1 lrwx—— 1 root root 64 2010-10-05 14:52 1 -> /dev/pts/1 lr-x—— 1 root root 64 2010-10-05 14:52 10 -> pipe:[15825] l-wx—— 1 root root 64 2010-10-05 14:52 11 -> pipe:[15825] lr-x—— 1 root root 64 2010-10-05 14:52 12 -> pipe:[15829] l-wx—— 1 root root 64 2010-10-05 14:52 13 -> pipe:[15829] …
