An issue arises from the following discussion:

It is related to issue #438 . The current implementation of
tril
,triu
and do_call do not take into account when the case kernel_sched returns LS and GS such that LS*GS < N.This PR is a quick fix by computing LS and GS itself and it guarantees LS*GS >= N.
I know that it may not be the most efficient value of LS, GS.
However, I am not sure the logic behind
kernel_sched
and I believe if I modify it, everything may be affected. Therefore I decided to lettril
andtriu
compute their own value of LS and GS intril
totriu
to fix it.
