More polution than climate change but still relevant in some ways.

Here in Cambridge, we broke the July record yesterday. I need to measure my arms to see how much longer they are from carrying watering cans around the allotment.


Not surprised at 381C!!!. Latest figure to be ratified is 38.7C from Cambridge Uni Botanic Garden

I know it is possible to set specific hours to either do work or access the network. How easy would it be to have it so that it woulde be possible to set specific hours to use all processors and a reduced number at other times e.g. use 50% 0f processors between 08:30 and 20:30 and 100% at other times?

8) Questions and Answers : Windows : Lost jobs and "busted" link (Message 60660)

There are settings in Windows somewhere that allow you to control when MS can do their updating,


If you do use older versions of Windows (pre Win10) then be aware that udpdate support for anything XP and earlier does no longer exist. This does have the advantage of not being plagued by "your computer needs updates" messages. Win7 support I am not sure of, however it did give you the option of checking if there were any updates and also installing them individually. The default for Win10 is "we will do everything for you", though there are workarounds for this but you need to be confident of making changes to the registry. Search the net for answers to this.

If you are worried about LAN activity there are settings in BOINC preferences that allow you to only use the network at certain times of the day (or even not at all).

To check if a task goes to jasmine search for the string, "upload_url" in your client-state.xml file and go through them till you find the one for the task in question. You should find something like the following,

[quote]wah2_safr50_n0ym_198912_13_820_011866056_0_r5511092_1.zip</name><nbytes>0.000000</nbytes><max_nbytes>150000000.000000</max_nbytes><status>0</status><upload_url>http://jasmin-upload.cpdn.org/cgi-bin/file_upload_handler


Or check the event log in the tools tab for the file transfer and you will get something like:

04/07/2019 22:15:49 | climateprediction.net | Started upload of wah2_safr50_n06x_201112_13_818_011860496_1_r430858283_5.zip

Patiently waiting for uploads to get going again!

Depends on where the data center is.
Might even be in the USA.


Apparently in Swindon, UK.

1. It's Suspend computations for each model.
This can be in the Menu under Activity if cpdn is the only project, or
In the Tasks tab, click each cpdn task in turn, and then click the Suspend button to the left.
Repeat.


Or suspend the whole project in thew PROJECTS tab. Quicker than individual tasks.

From the length of time this has been going on with Jasmin I would guess (perhaps incorrectly) that this is more than just a re-adjustment of quotas but an actual lack of physical hard drive space which of course takes time and money to solve.

You appear to have got credit on both of these. The statistics on BOINC manager look as if they have been updated today (23:40BST)
