Good day. I have 12 cores. So nthread() gives 12. when I used "Threads.@threads for ", only 8 thread was created. RAM memory was utilized for up to 85%. Can memory limitations and the number of thread created be connected? thanks.

Maybe I got the answer “Threads.@threads for” tries distribute evenly a number of threads since when I have exactly 12 files, 12 threads were created.

function main() files=readdir() Threads.@threads for file in files if file[end-1:end]=="gz" println("threadid-",threadid(), " ", file) df=ParseFile(file) println("threadid-",threadid(), " ","Parsefile") df=KeepUniqueId(df) …

[image] BMval: files=readdir() Threads.@threads for file in files How many files are in that directory?

Around 10-12. it’s more than a number of threads.

Why "Threads.@threads for " doesn't use all possible threads?
