Markii hore, waxaan haysanay hal CPUs oo xudun ah^{(single core CPUs)} . CPU-yadaan^(CPUs) waxaa lagu xiray xawaare gaar ah waxayna ku soo bandhigi karaan waxqabadka xawaarahaas gaarka ah. Ka dib waxaa yimid da'da CPU-yada^(CPUs) leh dhowr nooc^{(multiple cores)} . Halkan, xudunta udub-dhexaadka ahi waxay si madax-banaan u gudbin kartaa xawaaraheeda. Tani waxay si xad dhaaf ah u kordhisay awoodda CPU -ga waxayna markaas kordhisay waxqabadka guud ee aaladda xisaabinta. Laakin rabitaanka bini'aadmigu waa inuu had iyo jeer raadiyo xitaa si ka sii wanaagsan. Sidaa awgeed^(Hence) , multithreading ayaa la soo bandhigay taas oo wax yar kordhisay waxqabadka - laakiin ka dib yimid Hyper-threading . Waxaa markii ugu horreysay la soo bandhigay 2002 iyadoo la adeegsanayo Intel's Xeon Processors. Iyada oo la hirgeliyey hyperthreading, CPU had iyo jeer waxaa lagu mashquulsanaa fulinta hawsha qaar.

Waxaa markii hore lagu soo bandhigay Intel's Xeon chip, ka dibna waxay u soo muuqatay SoC-yada macaamiisha ku salaysan ee Pentium ^(SoCs)4^{(Pentium 4)} . Waxay ku jirtaa Intel's Itanium , Atom iyo sidoo kale Core 'i' taxane ah oo soo saareyaasha.

Waa maxay HyperThreading ee kombiyuutarada?

Waxay la mid tahay samaynta wakhtiga sugitaanka ama daahitaanka CPU si uu hal hawl uga beddelo mid kale inuu noqdo mid dayacan. Waxay u ogolaataa xudunta kasta inuu si joogto ah u socodsiiyo hawlaha iyada oo aan wakhti sugitaan lagu lug yeelan.

Iyada oo la adeegsanayo Hyperthreading , Intel waxay rabta inay hoos u dhigto wakhtiga fulinta hawl gaar ah oo hal xudun ah. Tani waxay ka dhigan tahay in hal xudun oo processor-ku uu fulin doono hawlo badan oo midba midka kale ka dambeeya iyada oo aan la daahin. Ugu dambeyntii, tani waxay hoos u dhigi doontaa waqtiga loo qaatay in hawsha si buuxda loo fuliyo.

Waxay si toos ah uga faa'iidaysanaysaa qaab dhismeedka superscalar kaas oo tilmaamo badan oo ku shaqeeya xog gaar ah ay saf ugu jiraan habaynta hal xuduneed. Laakiin tan, nidaamka qalliinka waa inuu sidoo kale la jaan qaadaa. Tani waxay ka dhigan tahay in nidaamka qalliinka uu yahay inuu taageero SMT ama isku mar isku-dhafan.

Sidoo kale, sida uu qabo Intel , haddii nidaamkaaga hawlgalka uusan taageerin shaqeyntan, waa inaad kaliya joojisaa hyperthreading.

Qaar ka mid ah faa'iidooyinka Hyperthreading waa:

1. Isku^(Run) mar wada socodsii codsiyada dalbanaya adigoo ilaalinaya ka jawaab celinta nidaamka
2. Nidaamyada ilaali, hufan, oo la maarayn karo iyadoo la yareynayo saameynta wax soo saarka
3. Bixi^(Provide) qol- madaxeed kobaca ganacsiga mustaqbalka iyo awoodaha xalinta cusub

Isku soo wada duuboo, haddii aad haysato mishiin loo isticmaalo in lagu xidho dhawr santuuq, mishiinku waa inuu sugo ka dib marka la xidhxidho hal sanduuq ilaa uu ka helayo santuuq kale isla suunka qaadaha. Laakin haddii aan hirgelinno suunka kale ee wax qaada ee u adeega mashiinka ilaa kan ugu horreeya uu ka soo saaro sanduuq kale, waxay kor u qaadi doontaa xawaaraha lagu xirxiro sanduuqa. Tani waa waxa Hyperthreading-ku awood u yeesho CPU -gaaga hal-core .

What is Hyperthreading in CPU and how does it work?

At first, we had single core CPUs. These CPUs were clocked at a certain speed and could deliver performance at that particular speed. Then came the age of CPUs with multiple cores. Here, every individual core could deliver its own speed independently. This exponentially increased the power of a CPU and thereby increased the overall performance of the computing device. But the human tendency is to always look out for even better. Hence, multithreading was introduced which slightly increased the performance – but then came Hyper-Threading. It was first introduced in 2002 with Intel’s Xeon Processors. With the implementation of hyperthreading, the CPU was always kept busy with the execution of some task.

It was first introduced with Intel’s Xeon chip, and then it made an appearance to the consumer-based SoCs with the Pentium 4. It is present in Intel’s Itanium, Atom as well as Core ‘i ‘ series of processors.

What is HyperThreading in computers?

It is like making the waiting time or latency for the CPU to switch from one task to another being negligible. It allows each core to process tasks continuously without any wait time being involved.

With Hyperthreading, Intel aims to bring down the execution time of a particular task for a single core. This means that a single core of a processor will be executing multiple tasks one after the other without any latency. Eventually, this will bring down the time taken for a task to be executed fully.

It directly takes advantage of the superscalar architecture in which multiple instructions operate on separate data are queued for processing by a single core. But for this, the operating system must be compatible too. This means that the operating system must support SMT or simultaneous multithreading.

Also, according to Intel, if your operating system does not support this functionality, you should just disable hyperthreading.

Some of the advantages of Hyperthreading are-

1. Run demanding applications simultaneously while maintaining system responsiveness
2. Keep systems protected, efficient, and manageable while minimizing the impact on productivity
3. Provide headroom for future business growth and new solution capabilities

Summing up, if you have a machine that is used to pack some box, the packing machine has to wait after packing one box until it gets another box from the same conveyer belt. But if we implement another conveyer belt that serves the machine until the first one fetches another box, it would boost the speed to pack the box. This is what Hyperthreading enables with your single-core CPU.
