HPC architecture (Commodity Cluster, Custom based solutions (mainframe)

We are sensing that the difference between the classic mainframe based resources (SMPs, NUMA systems) and the PC-based clusters has been dissolving as technological elements are mutually transferred between the two.

• How do you see this trend?
  • Vendor 1: Yes, agree. However, this trend will reach its limit in future.
• Do you think that the clustered environments will replace the classic mainframe models?
  • Vendor 1: PC-based clusters will not be able to replace classic mainframe resources at least for the next 5 years. Both will be always needed for certain environments.
• Or do you think that the classic mainframe architectures will survive within the multi-core server architectures?
  • Vendor 1: Yes, classic mainframe architectures will survive within the multi-core server architectures because mainframe resources also implement such technologies.

Processor architectures

The average number of cores in nodes has been increasing.

• Do you think that this trend will continue in the future?
  • Vendor 1: Yes, definitely.
• What do you think to be the largest core number in a single server in a year?
  • Vendor 1: 96
• Do you think that the increasing number of cores will not contribute to the performance increase sufficiently?
  • Vendor 1: Increasing number of cores will contribute to the performance increase sufficiently.
• Do you think that AMD and Intel will dominate the HPC market?
  • Vendor 1: Yes.
• Do you think that the graphics processors will keep representing an increasing share in the CPU portfolio?
  • Vendor 1: Yes, but this inclrese will go slower.

Interconnect technologies

• What do you think to be the most dominant interconnection platform in HPC?
  • Vendor 1: Infiniband

Operating system

HPC is traditionally performed in Linux/Unix environments. Nevertheless Microsoft keeps pushing in this area as well.

• Do you think that the amount of MS Windows operated centers will increase in the future?
  • Vendor 1: Not much.
• Do you think that Linux will outperform other Unix solutions in this field?
  • Vendor 1: Yes.
