Clustering runtime for 750K cells

[ahyeonhwang]

Hello,

I am currently running ArchR with 750K cells and the addClusters function has been taking over 2 days. I am using 30 cores and 1000G of memory. Do you know why this is taking so long? Any suggestions on making it run faster? With sampleCells=100K and 300K, the function took 3 hrs and 10 hrs, respectively.

Thank you very much for your help!

Best,
Ahyeon
