thx for your reply. i'm, performing 1-5 analysis every day usualy using 4-8 cores, it's first time i encounter such problem. i checked on other 3,5mln nodes model how it solves with 8cores and 1 gpu and it takes sekundes to write.

i'm using samsung evo 970 pro ssd drive.

as i have writen in previus reply, when solving without gpu accelleration there is no problem with writing solution file.
