[erlang-questions] Elbrus 2K support

[Max Lapshin]

As far as I understand, they are not related to Sparc anymore.   It was
some time ago, but they have made progress and now it is different.


About usage: it is not very clear, because they are very young as a
commercial product and haven't got wide distribution. But if you don't want
NSA backdoor, Elbrus is definitely worthy to look at =)
