Kinda annoyed no one ever explained race conditions to me before in terms of an actual race. Was just a word we were told was the name for the situation when two threads access the same resource with potential undesired consequences.

[@aaronhandleman7277]

It's worth mentioning that depending on the architecture, race conditions can be worse than just not knowing which item will be selected. You can end up in situations where the outcome isn't one of the two options. On certain architectures this can happen to primitives like numbers, but its easier to think about with an object. Say you have two threads racing to designate something as a "Yellow Truck" and "Blue Van". The object might store the color and type of vehicle separately. Moreover, just because thread 1 gets to the color field first, doesn't mean it will always get to the vehicle field first. So we can end up in a situation where the outcome is "Blue Truck" which wasn't either of our original options. On some architectures this can happen with integers because they span over multiple bytes, but those bytes may not be written as an atomic operation, so you could get the high bytes from thread 1 and low bytes from thread 2.

[@TheColorman]

That sounds super interesting, do you have any resources for learning more? E.g., on which architectrues this happens?

[@aaronhandleman7277]

@@TheColorman Afaik any architecture will make sure loads and stores are atomic up to the native word size, but that changes by architecture so arduinos could potentially have this happen with 32 bit integers since they have a 16 bit word. I don't have a specific resource, but you'll want to look into the architecture's memory model. The memory model defines how loads and stores interact when accessing memory.

[@somdudewillson]

Technically each individual outcome is still one of the two options in that case, the composite just isn't entirely one or the other.

[@aaronhandleman7277]

​@@somdudewillson Yeah, the point is just that not all architectures have atomics for some types we consider primitives. So if you're looking at a 32 bit int on a 16 bit wordsize architecture, technically the hardware instructions consider the int to be multiple concatenated pieces of information, but that isn't what we'd expect. There are also race conditions which can occur due to weirdness in the memory models. Most architectures assume that things are running on a single core. This allows the compiler or even the hardware to reorder some instructions however it wants. So, we could have some code where x and y both are initialized as 0 and we have 2 threads executing. Thread 1: store x = 15 store y = 25 Thread 2: read y read x print x, y Now you'd expect that the only options are (0,0), (15, 0), (15, 25), however we can also see (0, 25) due to hardware or software reordering on the write operations.

Fun fact: most modern apple processors don't have SMT (symmetric multithreading), which is what gives processor cores multiple threads because of the security concerns of SMT (namely: spectre). A 12 core M1 CPU will only have 12 threads (but even then only a few of them will be full power cores, the rest will be efficiency cores that run background tasks slower but at much less power, this is how M1 macbooks last all day on battery).

[@SaqibMubarak]

I don't think that's true bro, ARM based processors don't support SMT due to energy consumption reasons Hyper threading uses more power basically. AMD has also adopted SMT only in rect Zen architecture. It was an Intel proprietary technology. I don't think there is any security issue in using SMT, race condition can be easily solved by using semaphores(or soo many other methods). Also SMT means Simultaneous multithreading not Symmetric.

@@SaqibMubarak i never majored comp sci and i knew he was bull shitting, 90% of youtube comments that frame themselves as facts are people pulling shit out their arse(that statistic i pulled out my arse it is an arbitrary number)

[@DominicI1]

Even if it did have symmetric multi-threading, multiple threads attributed to a core are not *actually* capable of running multiple processes simultaneously. In reality, regardless of the number of threads a core has (1 or 2), there can only be one process running on a core at a given time. Hyper threading achieves a parallelism effect via utilizing "waiting periods" in one process (thread) to contribute to another. While in practice this give the illusion of parallel processing, it is merely an illusion and not in fact the case. Because of this hyper-threaded (intel's term) CPU cores do not gain a 2x performance via single threaded cores. Instead the performance is generally between 1.3-1.6x and in any case where there are no halts in processing the performance will be identical to that of a single threaded core. Also, in the case of "ARM based processors don't support SMT due to energy consumption reasons", this use to be partially true. There were other reasons behind this, such as design simplicity and the fact that that the original devices intended to run on ARM processors (smartphones & tablets) benefited more from increased core numbers than symmetric multi-threading. Heat was also an issue, because utilizing the waiting time between processes on a CPU involves increased utilization and therefor increased thermals, which is harder to manage on devices such as smartphones with limited cooling options. The biggest error in the statement was that they "don't support SMT", which is no longer the case (since at least 2018 with the Arm Cortex-A65). All in all, I would say that the response by @SaqibMubarak is about just as truthful as @Cadey 's comment, possibly less so. Everyone could use some constructive criticism now and then, including myself.

What the scheduler does is that he runs a process for some period of time, stores the state of the process for later, loads the state of another process, and so. This is called context switch and happens so fast that it gives the illusion of concurrency.
