有 db 可以係 gpu 入面行嘅咩
anyway 某原因所以係唔比用 gpu 的
我就係諗住要嘅話 query 用 simd 手寫
但係 sql 應該會方便少少

炒crypto要咩快
你話炒ETN/ETF就話要快啫

dataframe就大把gpu solution

sql本身定位個abstraction level就唔係low latency
放棄吧

手巴到而家都唔知個strategy要食咩
要食十年前既transaction定點

冇咁高端的
都係 普通
order book
trade accepted/rejected
transaction happened event

如果得嘅話我會想搞埋 backtracking 嗰啲
咁就可以行之前試下個 algo 先

咁你要咩春db? Db既significant係邊?
2022-10-01 13:41:10
我只係諗住 sql 會唔會方便啲寫
咁即係所有嘢 in mem columnar store 就夠?
冇 gpu 的我 simd 算

Order book -> 個feed自己會設計到可以intraday先開始收 會有snapshot比你 除非你話係啲濕鳩exchange咁就改你個strategy咪做複雜野
Trade / transaction -> 唔time critical就慢慢寫入db time critical就用完即棄 兩個需求都有就開兩個process


都唔關方唔方便事
亦唔關GPU事 你根本唔知佢講既GPU個use case係點 專心做你既野 唔好人地話佢用咩咩咩就話自己都要咩咩咩 兩個use case根本唔重疊
至於GPU可以做啲咩 就問返牙青 手巴無興趣講

你講既gpu係咪顯你老母卡?

因為樓上問到 indexing o(n)
所以題出gpu

ai art係咪art
2022-10-01 18:09:39
我純粹係擔心手寫 indexing 唔掂咁解

HR phone in左大概半個鐘, 之後約zoom interview
interview 果日見左兩個team lead 應該當兩round
見完冇耐收左依家公司既OFFER 照直同HKX個HR講左 佢話佢地內部開下會再睇下點
我就冇等佢地直接accept左offer 之後到依家幾個月都冇未再收到佢地update
其實都係red flag黎 個HR又話果日IN完佢地對我評價唔錯 但最後咩follow up都冇 email UP一句都夠啦啊 我仲講到明另一邊等緊我reply
