11:36 - 103 nodes (412 GPUs)が最初から故障 - 先生に修理依頼を出していただく運びになりかけたが、しばらくすると40ノードぐらいに故障ノードが減って、とりあえずよしとした。 - 512GPUs×7で実験が回っている。(新しいデータセットではまだ回ってない) - bceの挙動やLWNはまだ未検証なので、新しいデータセットについてはclippingだけを噛ませて回す運びになった。 - LWN, BCEのPT実験のタスクは張に任せる - 12:00 - 512GPUsx8で実験が回りだす - LWNを適用させるとスループットが半分ぐらいになる現象を確認(clipping時) - GPUが遊んだら、終わったやつのFTを流せるだけ流す方針 - 13:45-17:30 - 高島、対面講義にて離脱。B4と張にタスクの監視を依頼 - 18:00 - ExRCDB-21k PT-> ImageNet-1k FT N=384のlossがNaNに - とりあえずFT 2つをqdelしておいて、最初からampなしで回し始める。後でresumeした方がよさそう。 - 残り2つもNaNになったので、それらも最初からampなしで回し始める。 - 最初からやるのは、途中からamp外して行ったものとどれぐらい差が出るのか今の段階で見極めたいため。後で、途中からもampなしでresume回したい。→22:30に空いたので回し始める - ~~21:00~~ 21:30 - 中間報告 - v5が空いた分、v6を回す - v2, v3が続けて終わる見込み、ImageNet-1k FT (N=384)のampのresumeと、ワンインスタンスのサブタスクを回す見込み。 - 後は空いたそばから、終わった分のFTとかImageNet-1k FTを回していく。GPUなるべくたくさん使って良い。 - v4, baselineがおそらく2時間後の23:00とかに終わる。 - 21:10 - と思ったら、v2が謎のエラーで落ちてる。cuda通信エラー?回しなおす。これが何回か時間をおいて発生 - 深夜 - GPUが空いたら適当なImageNet-1k FTを投げる - swin PTやらImageNet-1k FTやらいろんなのがamp NaNで落ちるので、回し直し - また、なぜか資源が空いておりかつ故障ノードがない状況にも関わらずQWが続くことが多々あった。何回かqdelして再投入すると通る - 全体の9割以上のGPUを常に使い続けている状況を保つ - 4:10 - 高島 仮眠 - 30minに1回ぐらいでlogを見て、謎エラーやNaNで落ちていたら回しなおす。 - 7:00 - この辺りから近江くんにlogの監視を頼んでいたため、休む - 9:00 - 近江くんからの報告で状況を把握。v6のPTが終わっており1割ほどGPUに空きができていたが、あと少しなのでこのままstay - 11:00 - グラチャレ終了。上記表に実行状況を追記保存、resumeとFTに備える
