I-Slurm ye-AI Training Clusters
I-Slurm ingumphathi womthwalo ovulekile womthombo ovulekile ohlela futhi aqhube imisebenzi kumaqoqo ekhompiyutha asebenza kahle kakhulu, futhi sekuyisinqumo esizenzakalelayo sokuqeqeshwa okukhulu kwe-AI.
Uhlolojikelele
It matters because it reliably distributes massive training runs across thousands of GPUs.
I-Deep Dive
I-Slurm (I-Simple Linux Utility for Resource Management) iqale ku-supercomputing futhi manje inika amandla amaqoqo amaningi okuqeqesha e-AI amakhulu emhlabeni. Abasebenzisi bahambisa imibhalo yeqoqo ene-sbatch, izinsiza zokucela njengama-node nama-GPU aneziqondiso ezifana --gres=gpu:8, kanye nolayini be-Slurm, babeka phambili, futhi baqalise umsebenzi. Isiqalisi sayo se-srun siveza izinqubo ezididiyelwe kuwo wonke ama-node, abhanqa ngokwemvelo nezinhlaka ezisabalalisiwe njenge-PyTorch DDP ne-NCCL. I-Slurm ilandelela ukubalwa kwezimali kwensiza, iphoqelela ukwabelana okufanelekile nemikhawulo yokuhlukanisa, futhi isingatha ukuhlela kokugcwalisa ukuze kufake imisebenzi emincane ezikhaleni. Ngokuqeqeshwa kwemodeli yasemngceleni, amaqembu athembele ku-Slurm ukuze alawule izinkulungwane zama-GPU, aqale kabusha ezindaweni zokuhlola ngemva kokuhluleka kwama-node, futhi agcine umthamo ozinikele wokugijima amaviki amaningi.
I-Technical Insight
I-daemon yesilawuli se-Slurm (slurmctld) yenza izinqumo zokuhlela kuyilapho i-ejenti ye-slurmd endaweni ngayinye ivula imisebenzi futhi ibika isimo. I-plugin ye-Generic Resource (GRES) ilandelela ama-GPU ukuze imisebenzi iwacele ngokusobala. I-srun isetha okuguquguqukayo kwemvelo (izinga, usayizi womhlaba, ikheli eliyinhloko) esabalalisa imitapo yolwazi yokuqeqesha efundelwe ku-bootstrap ukuxhumana kwe-NCCL. Ukuhlelwa kokugcwalisa emuva kuvumela imisebenzi emifushane ukuthi isebenze kusenesikhathi inqobo nje uma ingabambezeli ukubhukha okubaluleke kakhulu, okugcina ukusetshenziswa kuphezulu.

Izindleko kanye nesabelomali
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka.
Izinqumo ezicacile
Imfundo yobuchwepheshe isiza amaqembu ukuthi akhethe isitaki esifanele, hhayi nje esisha.
Ukulawulwa kwekhwalithi
Izinketho ezingcono zobunjiniyela zinciphisa izehlakalo ezinokwethenjelwa ekukhiqizeni.
Ikusasa le-Slurm lama-AI Training Clusters
I-Slurm iyaqhubeka nokwengeza ukuqhuma kwamafu, ukusekelwa kweziqukathi nge-Pyxis ne-Enroot, nezici eziqaphelayo ze-GPU eziqinile. Njengoba amaqoqo e-AI efinyelela ku-100,000-plus GPUs, lindela ukubekezelela amaphutha okuqinile, ukuhlanganisa okuzenzakalelayo kokuhlola-ukuqalisa kabusha, nemisebenzi enwebekayo eshintsha usayizi ngemva kokwehluleka. Izinhlangano eziningi manje zisebenzisa i-Slurm eceleni noma ngaphansi kwe-Kubernetes, futhi abahleli be-hybrid bahlose ukuhlanganisa ukusebenza kahle kwesitayela se-HPC nokuguquguquka kwemvelo kwamafu kokugijima okuhlala kukhudlwana kokuqeqeshwa.
Ukuqaliswa Komhlaba Wangempela
Ilebhu yasemngceleni yethula ukuqeqeshwa kwamasonto amaningi okugijima phakathi kwezinkulungwane zama-GPU ngeskripthi esisodwa se-sbatch esicela amakhulukhulu wamanodi.
Umcwaningi uhambisa okuthi 'srun --gres=gpu:8' ukuze abambe ama-GPU ayisishiyagalombili endaweni eyodwa ukuze kuhlolwe i-PyTorch DDP.
Ukushejula kokugcwalisa emuva kubeka umsebenzi wokuhlola omfushane kuma-GPU angenzi lutho kuyilapho umjaho omkhulu wokuqeqesha obekelwe ulinde ukuqala.
Ngemuva kokuthi i-node ihluleke phakathi nokugijima, i-Slurm iphinda ilandele umsebenzi futhi iqala kabusha endaweni yokuhlola yakamuva esikhundleni sokuqala kabusha.
