cpu | cpu command in Go , inspired by the Plan 9 cpu command

The Unicode output of WMIC encoded with UTF-16 LE with BOM (byte order mark) can be filtered with two FOR loops to get just the wanted data written into an ASCII encoded text file.

It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.

Send your data to separate processes. I used concurrent.futures because I like the simple interface.

This runs in about 11 seconds on my computer.

I would suggest you to use conda (Ananconda/Miniconda) to create a separate environment and install tensorflow-gpu, cudnn and cudatoolkit. Miniconda has a much smaller footprint than Anaconda. I would suggest you to install Miniconda if you do not have conda already.

The math module consists mostly of thin wrappers around the platform C math library functions.

While python itself can only execute a single instruction at a time, a low level c function that is called by python does not have this limitation.
So it's not python that is using multiple cores but your system's well optimized math library that is wrapped by python's math module.

That basically answers both your questions.

Regarding the usefulness of multiprocessing: It is still useful for those cases, where you're trying to parallelize pure python code or code that does not call libraries that already use multiple cores. However, it comes with inter process communication (IPC) overhead that may or may not be larger than the performance gain that you get from using multiple cores. Tuning IPC is therefore often crucial for multiprocessing in python.

Thanks Hernando - MSFT for helping me. The Accept button in the Licence agreemnet window can be clicked by moving back and forth the hand using W,A,S,D keys.

Previously i thought that i should click using a raycast pointer. It would be nice if i can click using raycast because the current approach is very difficult for any new users.

Additionally, sometimes mouse and keyboard inputs doesn't worked for me. This is because the 'Use Mouse' and 'Use Keyboard' check-boxes under the Simulation Panel is disabled. We have to ensure they are enabled for using mouse and keyboard for simulation inputs.

You've made a mess of things by incorrectly installing the module. Specifically, you didn't install the dependencies.

Ideally, you should use the package manager that provided perl itself. But they don't provide every module. So you'd use the non-package manager approach:

We needed the adress of t0

Registers don't have addresses: they have names; they have positions/index in the register file, and, they hold values.

Only memory has addresses.

Since, lw, does need the correct value of mem[$t0] + 4

That lw accesses mem[$t0+4], and it needs $t0's value so it can do the + .

The lw and sw instructions compute an effective address:

There are concrete efficiency losses because of the inefficient use of threads. Each thread requires at least 1 MB for its stack, so the more threads that are created in order to do nothing, the more memory is allocated for unproductive purposes.

It is also possible for concrete performance losses to appear, in case the demand for threads surpasses the ThreadPool availability. In this case the ThreadPool becomes saturated, and new threads are injected in the pool in a conservative (slow) rate. So the tasks you create and Start will not start immediately, but instead they will be entered in an internal queue, waiting for a free thread, either one that completed some previous work, or an new injected one.

Regarding your concerns about creating busy waiting procedures, no, that's not what happening. A sleeping thread does not consume CPU resources.

As a side note, creating cold Tasks using the Task constructor is an advanced technique that's only used in special occasions. The common way of creating delegate-based tasks is through the convenient Task.Run method, that returns hot (already started) tasks.
