Izindaba

Njengoba izinhlelo ze-computing eziphakeme (HPC) ziba zinkimbinkimbi ngokwengeziwe, kubalulekile ukusebenzisa uhlelo olusebenzayo lokusabalalisa kwamandla. Amayunithi wokusatshalaliswa kwamandla (Pdus) abalulekile ekuqinisekiseni ukuphepha kanye nokusebenza kahle kwemisebenzi ye-HPC. Kulesi sihloko, sizoxoxa ngokusetshenziswa kwe-PDU ku-HPC kanye nezinzuzo abazinikezayo.

Yini i-pdus?

I-PDU iyiyunithi kagesi esabalalisa amandla kumadivayisi amaningi noma amasistimu. I-Pdus isetshenziswa kakhulu ezikhungweni zedatha kanye nezindawo ze-HPC ukuphatha ukusatshalaliswa kwamandla ngokuphepha nangendlela efanele.

Izinhlobo ze-Pdu

Izinhlobo eziningi ze-PDUS ziyatholakala ku-HPC Operations. I-Pdus eyisisekelo inikezela ukusebenza kwamandla okusatshalaliswa kwamandla. I-plus ehlakaniphile inezici ezithuthukile, kufaka phakathi ukuqapha okukude, ukuqapha ukusetshenziswa kwamandla, kanye nezinzwa zemvelo. I-PDUS eshintshiwe Vumela Ukuhamba Kwamandla Okukude Kwezitolo Ngamunye.

Kusetshenziswa kanjani i-pdus ku-HPC

I-Pdus isetshenziselwa ukulawula ukusatshalaliswa kwamandla kwemisebenzi ye-HPC, ukuqinisekisa ukusebenza kwayo okusebenzayo nokuthembekile. Njengoba amasistimu we-HPC adinga amandla amakhulu futhi asebenze amadivayisi amaningi ngasikhathi sinye, ukuphathwa kwamandla okusatshalaliswa kwamandla okusebenzayo kubalulekile.

Izinzuzo ze-PDU ku-HPC

Ukuphathwa kwamandla kwe-PDU okusebenzayo ku-HPC kunikeza izinzuzo eziningana, kufaka phakathi:

1. Ukwanda kwesistimu ngesikhathi: I-PDUS inika amandla izimpendulo ezisheshayo ekuphelweni kwamandla, ukunciphisa isikhathi sokuphumula nokwenyuka kohlelo isikhathi.

2. Ukusebenza kwamandla okuthuthukile: Pdus ngezici ezithuthukile ezifana nokuqapha ukusetshenziswa kwamandla kungalungisa ukusetshenziswa kwamandla, okuholele ekulondolozeni izindleko ngokuhamba kwesikhathi.

3. Ukuthembela okuthuthukile: Pdus ukuhlinzeka nge-redundancy, eqinisekisa amasistimu abucayi anokuhlinzekwa ngamandla amandla.

Ukugcina

I-Pdus ibalulekile ekusebenzeni kwe-HPC njengoba iqinisekisa ukuphepha nokusebenza kahle. Uhla lwezinhlobo ze-PDU olutholakalayo luvumela izici ezithuthukile, ngcono ukuphathwa kwamandla okusatshalaliswa kwamandla, kanye nokuqinisekisa ukusebenza kahle kokusebenza. Ngezinzuzo zokuthuthuka kohlelo, ukusebenza kahle kwamandla, kanye nokwethenjwa okuthuthukile, izikhungo ze-HPC zinokutshalwa kwezimali okugxekile ku-PDU ekuphathweni kwamandla okusebenzayo.
