<br>
HPC, like most things, exists to get something done.<br>
<br>
If HPC doesn't change to reflect the changes in society and the way<br>
the software is developed (*) then the users will look for more modern<br>
ways to replace traditional HPC. As noted the software is no longer<br>
developed on workstations that are connected to the lab/company<br>
network but rather on laptops that stay with the user wherever they<br>
go.<br>
<br>
This in turn is at least in part what has driven to the rise of<br>
distributed version control, git in particular.<br>
<br>
If HPC doesn't make it easy for these users to transfer their workflow<br>
to the cluster, and the cloud providers do, then the users will move<br>
to using the cloud even if it costs them 10%, 20% more because at the<br>
end of the day it is about getting the job done and not about spending<br>
time to work to antiquated methods of putting jobs in a cluster.<br>
<br>
And of course if the users would rather spend their department budgets<br>
with Amazon, Azure, Google, or others then the next upgrade cycle<br>
their won't be any money for the in house cluster...<br>
<br>
<br>
* - note the HPC isn't unique in this regard. The Linux distributions<br>
are facing their own version of this, where much of the software is no<br>
longer packagable in the traditional sense as it instead relies on<br>
language specific packaging systems and languages that don't lend<br>
themselves to the older rpm/deb style system.<br>
