4. HPC Customer Pain Points
Complexity Maintenance Time to Solution
“My IT staff doesn’t have
time to update and test all
the different software
components.”
• Better management
software is needed, and
deployment approach
needs to be updated to
leverage HPC and cloud
infrastructure
• Stack components provided
by multiple vendors, making
it more challenging to
maintain
“I need to maximize
application performance,
scale workloads, and
minimize overhead.”
• Parallel software is lacking
with many applications
needing a major re-design
• Stack components provided
by multiple vendors, making
managing more challenging
• Segmented into commercial
and scientific, and there is
not enough collaboration
• “Composing a working
HPC environment is
difficult, time-consuming,
requiring experts.”
• Clusters are hard to use
and manage as they
become more complex in
heterogeneous
environments
• Storage access time and
data management are
becoming new bottlenecks
