7.14 i will try to download 7.15
OSX runs 12,6 hours and is granted 37 points/hour Linux runs 17,1 hours and is granted 5 point/hour Mac is intel i5, Ubuntu runs on i7 Problem is not the time consumption onlybut more the lousy points. |

Seeing significant performance improvement on Linux 64 bit, typically processing a WU is going from about 17 down to 11 hours of runtime on the same PC.

Finally got back the the lone FAH2 unit to compare to the four Beta unit which happened to occur on the same machine and which were all manually started within seconds of each other.
----------------------------------------FAH2_ avx38741-ls_ 000063_ 0016_ 002_ 0-- mint Valid 10/8/15 19:04:40 10/11/15 04:24:29 41.24 / 41.26 440.4 / 440.4 BETA_ FAH2_ avx101119_ 000064_ 0056_ 001_ 0-- mint Valid 10/9/15 07:49:21 10/10/15 17:11:13 29.45 / 29.46 447.4 / 447.4 BETA_ FAH2_ avx101119_ 000002_ 0027_ 001_ 0-- mint Valid 10/9/15 05:05:20 10/10/15 17:11:13 29.85 / 29.86 453.5 / 453.5 BETA_ FAH2_ avx101119_ 000086_ 0003_ 001_ 0-- mint Valid 10/9/15 03:40:01 10/10/15 19:47:59 32.55 / 32.56 494.4 / 494.4 BETA_ FAH2_ avx101119_ 000020_ 0021_ 001_ 1-- mint Valid 10/9/15 02:28:53 10/10/15 19:47:59 32.21 / 32.22 489.3 / 489.3 This would be a 24.8 % improvement in the run time of the BETA units (BETA average of 31.02 divided by the FAH2 time of 41.24). Even though this reflects only a single data point for FAH2, I think it is in line with what others have also found. Linux Mint 17 on a Xeon 5320 running off a flash drive. Cheers

Comparisons between Betas under Linux Virtual Machines vs Windows x64 Native
----------------------------------------Linux VMs are Debian 7 or 8 x64, running under VMWare 10 ======================================================================= Based on CPU times, not elapsed times. Machine: "Callisto" - 3770K @ 4.3GHz, mem 1866MHz, C9: Running 7 cores Linux - OET + FAHB beta, host 1 core Windows 7 x64 - FAHB. Linux Betas - average of 7 = 11.6h Windows production - average of 2 = 10.3h * Linux takes 13% longer than Windows --------------------------------------------------------- Machine: "Io" - 3770K @ 4.0GHz, mem 1866MHz, C9: Running 7 cores Linux - OET + FAHB beta, host 1 core Windows 7 x64 - FAHB. Linux Betas - average of 7 = 12.8h Windows production - average of 2 = 11.3h * Linux takes 13% longer than Windows --------------------------------------------------------- Machine: "Charon" - 2600K @ 4.0GHz, mem 1066MHz, C7 Running 7 cores Linux - OET + FAHB beta, host 1 core Windows XP x64 - FAHB. Linux FAHB betas - average of 7 = 14.7h Windows production - average of 2 = 11.8h * Linux takes 25% longer than Windows --------------------------------------------------------- Machine: "Triton" - i7-970 (LGA1366 Gulftown hex-core) @ 3.9GHz, mem 1288MHz, C7 (only 2 channels, 3 supported) Running: - Native (host) - 4 cores Win 7 x64 - FAHB - Linux VM #1 - 4 cores OET + FAHB beta - Linux VM #2 - 4 cores DENIS@home + FiND@home (VINA) Linux FAHB betas - average of 4 = 16.6h Windows production - average of 2 = 14.4h * Linux takes 15% longer than Windows --------------------------------------------------------- Note: On all machines, running OET WUs were suspended to run the FAHB betas. On the 2600K and 3770Ks, 4 or 5 betas were started initially. Then, after the remaining OETs had finished and the suspended tasks had been resumed, the remaining betas were started. The FAHB betas may have run more slowly when they occupied all cores. ---------------------------------------------------------- Conclusion: The Virtual Linux FAHB betas ran much faster than the previous FAHB production WUs, but they still run more slowly than FAHB under Windows x64. Some of the difference might be explained by the overhead of the VM, but on the other hand the VMs may actually run more efficiently than native Linux. One beta was received & run on another machine under native Linux (no Windows FAHB WUs for comparison), and as is also the case for OET, the ratio of CPU/elapsed time was worse under native Linux than is achieved by the other machines running Linux in VMs. (The Intel virtualisation feature (VT-x) in the BIOS is set to On in all CPUs.) Hope this helps ... [Edit 1 times, last edit by Rickjb at Oct 11, 2015 11:39:57 AM] |

Finished on track:
BETA_ FAH2_ avx101119_ 000044_ 0013_ 001_ 0-- starbase3.command Valid 10/9/15 05:45:54 10/11/15 11:49:44 41.33 / 42.97 263.2 / 263.2 Looks like the beta versions are saving around 22% crunching time. |

Is anyone else seeing low CPU usage?
----------------------------------------On my dual Xeon E5-4667 v3 setup (32c/64t) I normally see a 15-minute load average (as reported by the 'uptime' command in Linux) of about 68 or 69. Last night while this system was running almost entirely FAAH-Beta WUs, the load average was much lower--about 40 or so. I opened up System Monitor to see indeed that a bunch of the vCPUs were bouncing around, often hitting as low as 10% activity. RAM usage wasn't a problem--I was only at about 4.5GB of 8GB in the system (and BOINC is told that it can use up to 80% of the RAM the computer has).  |

Not here. According to Boinctasks all 3 rigs running 16c/32t E5's are above 99%. results suggest each thread is losing 3mins over 16 hrs on 1st, about 10 mins in 23 hours on 2nd and less on 3rd
----------------------------------------This is running Linux Mint 17.n and with <no_priority_change> set in order to let the kernel do the scheduling  [Edit 1 times, last edit by OldChap at Oct 11, 2015 7:56:30 PM] |
