Well, it’s using ~ half the available cores… if I had 2 cores and one of them was being used by Julia, I wouldn’t be worried. If i had 10 cores and 5 of them were in use by Julia… I wouldn’t be worried…
If I have 64 cores and 32 are being used by Julia… should I be worried? I mean, maybe you want to limit it further… sure… but it’s not really a “huge” load for such a server.
In any case, if it’s BLAS that’s the issue, you can use BLAS.set_num_threads() to limit its thread count.
