We don’t use perl for everything, yes we use it for web data, yes we still use
it as the glue language in a lot of cases, the most complex stuff is done with
C (not even C++ as that is too slow). Others on site use Python, Java, Rust,
Go, PHP, along with looking at using GPUs in cases where code
James would you be able to share more info about your setup ?
1. What exactly is your application doing which requires so much memory and
CPU - is it something like gene splicing (no i don't know much about it
beyond Jurassic Park :D )
2. Do you feel Perl was the best choice for whatever you are do
Oh but memory is a problem – but not if you have just a small cluster of
machines!
Our boxes are larger than that – but they all run virtual machine {only a small
proportion web related} – machines/memory would rapidly become in our data
centre - we run VMWARE [995 hosts] and openstack [10,000s
