I spend a daily portion of time on the way to and from work that's about a total of two hours, and wanna keep my laptop up in that period, however, the issue is that with the potential shakes the laptop experiences on the way, it doesn't only stop the crunching, but starts over from the beginning the WUs it's got in hand.
Is there a way to make the BOINC resume the WUs in hand when the laptop shakes/freezes ? Cheers, Amr |

Did you try to enable "Leave application in memory when suspended" in BOINC Manager preferences?

[Assuming] Cairo roads are as good as our Italian regionals, so if that is a work machine particularly, I'd not run risk of a head crash on the platter, it surely will shorten live. If a device resets then LAIM wont rescue progress... nothing will unless a *good* checkpoint save was made by the task [default at most once per 60 seconds, often with larger intervals, and for CEP2, multiple hours interval on a laptop.] If the task was in the middle of a checkpoint save when freezing, it could turn out to be as bad as going back to 0.0% progress. Gain nothing and risking the hardware.

Cheers, Amr Dotsch has a Linux app that can run Boinc on a thumb drive, maybe you could do that and skip the hard drive altogether. Just use a 4 or 8 gb thumb drive and install Boinc to it thru Windows, or Linux should work I would think. Heck if you keep the cache small a 2gb drive would work.   |

Word of caution: If you run Clean Energy 2 on a thumbdrive, the amount of disk reads/writes will probably wear it out relatively quickly. Other projects should be OK. I don't know if this is an option but you could make a sling for your laptop to ride in which would mitigate the bouncing around it would do. It would only sway which is a much smoother motion, not as jarring. Good luck. Cheers

It works really nicely on an SD Card in your laptops card reader
---------------------------------------- Try downloading the universal usb installer and install, with a persistence file of around 1GB, a flavour of Ubuntu ISO file (my favourite being Xubuntu ) onto your SD card, the 64 bit version or the 32 bit version dependant on the capability of your laptops processor (you may need to acknowledge the fact that the card/usb stick has tried to autorun during the install as this may be blocked by your PC or virus scanner) Run Ubuntu from the card ( or usb stick) - this may require a modification in your BIOS as to which drive boots first, make it your SD Card or USB Flash Drive - and most importantly don't install it on the Hard Drive - Welcome to Linux  - connect via Wifi or Ethernet to the Internet - then install BOINC from the Software Centre which is really easy, just type BOINC into the Software Centre search box and select the BOINC software package to install, and before you know it you can crunch without ever using your hard drive. To get the most out of your laptop make sure you remember to select the continue crunching while on battery option and also set the "While processor usage is less than" to 0 from 25 - switch off the Linux screensaver .... and Bob's your Uncle your in business. A cheap 2GB SD card is more than sufficient If anyone asks..... I never told you how  Dave p.s. be careful - this is my disclaimer - it is entirely your responsibility to make sure in all of this that your current hard drive based OS and all your lovely files, pictures, movies, music and documents stays intact Dave (again)  [Edit 16 times, last edit by David Autumns at Sep 15, 2012 12:00:14 AM] |

If you go to all this effort, why don't you just plug the SD card into a computer? Why go to the effort of fooling yourself by using the SD card in a car?

The original post was about driving on VERY bumpy roads and wanting to crunch at the same time. and my post (indirectly) was why put an SD card in your car for 20 minutes on your drive to work when you can put it in a computer for 24x7 where there are no bumps |
