The two graphs above depict the HEPSEPC06 scores comparison for the EC2 M1 Medium instance <strong>and</strong> <br />
corresponding in-‐house HTC instance at INFN with Intel <strong>and</strong> AMD processor. From the graphs following <br />
observations could be made: <br />
• Intel processor is better in performance as compared to the AMD Opteron (please note the y-‐axis scale <br />
for Intel vs. AMD). <br />
• Performance degradation while comparing the AMD Opteron bare-‐metal <strong>and</strong> EC2 virtualised instance are <br />
significantly low as compared to the Intel S<strong>and</strong>y Bridge. <br />
• For the worst-‐case (i.e. all VMs running HEPSEPC06) the EC2 outperforms both the in-‐house instances i.e. <br />
with Intel <strong>and</strong> AMD processors. In all the other cases, in-‐house HTC instance is better as compared to the <br />
EC2. <br />
• The minimal effect of virtualization is notable by comparing the HEPSPEC06 scores for the bare-‐metal vs. <br />
1 virtual machine. Also, this trend continues even with the increase in the number of virtual machines. <br />
• 47.95% average performance loss (ranging from 2.38-‐58.48%) while comparing the HEPSEPC06 scores <br />
between EC2 <strong>and</strong> HTC instances (with Intel processors) at INFN. <br />
