Has anyone had any experience with the difference in crunching-capability between AMD Opteron and Intel Xeon CPUs?
----------------------------------------For vaguely the same price, I can get: Twin-node 1U chassis (two servers in a single 1U chassis):or Quad-CPU 1U chassis: Have always rated Intel higher than AMD, but there's quite a difference between 64 cores in the AMD chassis, and 48 threads (24 hyperthreaded cores) in the Intel chassis.  |

Normal supply of HPF2 has finished! My calculations show me 4 days short pf Sapphirw. It was always going to be a close thing to reach Sapphire for both GFAM & HPF2 when they were both finishing so close to each other. So I'll settle for GFAM and hope they find some loose change in he budget to restart HPF2 at some time in the future.Experience has shown picking up 4 days of work from resends is an impossible dream, so I'll void my cached WUs and hit DSFL before the feeding frenzy bwgins there.Shpuld male Sapphire by mid July. Another "damn close run thing" given the speculation of a late July end. I've been following the rate of drop of DSFL days left. It seems to be dropping by about 4-5days a day. This seems to be from a daily completion % rise 0.19-0.2-0.21 etc. So the 'feeding frenzy' seems to have already begun increasing about 5% a day over the last few days. |

@ Maugan
----------------------------------------I think you right. Looking at the DSFL Stats Results Returned have increased from ~130k per day to ~170k per day. But the UK team is in the vanguard with DSFL having grown from 14.44% of team RT to 35.98% in the last 7 days. No time to provide more specific stats. As result of gordoma's poking I've been "volunteered" for an enormous stats project which is occupying most of my time - personal and computer.  |

In the lunchtime stats update I see that I exceeded 75K results for the grid. Only some 27K are for team UK, but I'm not planning on going anywhere.

Unfortunately I have no idea Thargor, but I wish I had either option in my fleet. I would think that you would make number one spot in the team rather quickly with either!

Hi, If it matters, I found two BOINC hosts with those CPU's Intel(R) Xeon(R) CPU E5645 AMD Opteron(TM) Processor 6274 Both are running linux. The Intel one shows up as 12 cores while the AMD shows up as 32 cores(Hyperthreading?) Intel: Measured floating point speed 2545.73 million ops/sec Measured integer speed 9656.19 million ops/sec AMD: Measured floating point speed 1721.59 milion ops/seg Measured integer speed 5650.92 milion ops/seg ]The Opteron has a TDP of 115 watts with an average CPU power of 80 watts The Intel has a TDP of 80 watts Hope any of this helps.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

Thanks Falconet, that does reinforce my thoughts about going with the Intel chassis!
----------------------------------------I'll drop the company an email with a few questions, as I'm still unsure on a few details around how the twin-node setup in a single chassis with shared backplane works - I've only assumed I'll need a RAID-card and pair of drives for each node, that might not be the case. |

Good Morning Team, rather damp and dreary where I am, hope some of you are getting better weather.
