As explained for the version 7.0.38 https://boinc.berkeley.edu/dev/forum_thread.php?id=6698 (scroll down near to the end) - HFCC suffers from an issue realted to the old heartbeat mechanism - at least on my older system where HFCC tasks often ended with "Computation error" just because the external USB disk is too slow.
/me wonders whether a new HFCC version will be built upon the new libs of the BOINC client to use the new feature too. |

It's *NOT* a science issue, it's a BOINC client issue [kill science if not getting an "I'm alive" every 30 seconds], which with 7.0.38 should have been send to permanent hunting grounds up in the sky. If you have it, it's your system that's generally not coping... too busy and failing to allow other processes some interrupts to report to BOINC. Hyperactive security software is one cause [exclude BOINC data dir from scanning] or extensive disk IO is another [too many memory hogs, swapping their blocks back to disk e.g.]

yeah - I've exactly such high i/O load + slow external disk which I'm suffering currently. 7.0.38 is Windows only currently - so I do have to wait till the svn repo contains a tag for Linux user too.

Think to have read that Gianfranco is working on a 7.0.38 Debian port, but his last attempt failed due a missing file.
----------------------------------------Certainly putting BOINC data directory in it's own/exclusive logical partition, or at least defragging your disk would speed up matters. That said, if this is Linux, then ignore defrag... the system is way ahead of Windows to prevent fragmentation [Maybe the next Windows will have that new filesystem, half ripped from Linux]. Still, Windows 7+8 performs for me superb when it relates to CEP2, and that *is* the number 1 disk I/O demanding science.... 99% efficiency. Corr. Gianfranco got a 7.0.38 build up for Quantal and Precise in his ppa [LocutusOfBorg] edit: *own/exclusive* [Edit 1 times, last edit by Former Member at Nov 10, 2012 10:04:10 AM] |

Well, not too much what I can do here. I'm running a stable Gentoo Linux booted from a ext4 hard disk, but that hard disk as an external USB 2.0.
OTOH a know a little bit about compiling, make, subversion and so on - something I can help to make 7.0.38 up and running ? |
