Is there any chance that your system doesn't have enough memory to run that many instances of the program? I'm just guessing but it sounds like it had a problem allocating "Thread Local Storage", which is memory used for communicating between threads.
2) Message boards : Number crunching : One WU says it will take 4+ days to complete - normal time is < 45 minutes (Message 3623)
Posted 18 Jan 2016 by David Ball
I have a workunit which has run for 2 hours 23 minutes and is only 2% complete. It says it will take 4 days and 21 hours to complete.

https://mindmodeling.org/workunit.php?wuid=20966706

I have another which has run for 25 minutes but is also still at 2%. Should I abort these workunits?
3) Questions and Answers : Web site : Website starting to use invalid url 192.168.108.111 (Message 2689)
Posted 7 Nov 2013 by David Ball
The website is starting to use links to the url http://192.168.108.111

This URL will NOT work over the internet. The subnet 192.168.x.x is reserved as a private address for local networks. You can find info on this in rfc1918 (Address Allocation for Private Internets) at

http://tools.ietf.org/html/rfc1918

The Internet Assigned Numbers Authority (IANA) has reserved the
following three blocks of the IP address space for private internets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)


For instance, if you will be using several machines on your internet connection at your home, you will often get a router from your isp which uses a single routable public internet address and assigns each of the local machines a private address in the 192.168 subnet. When a local machine talks to the internet, the router remaps the 192.168 private subnet address to the single public internet address which can be sent over the internet and remaps the responses to the local machine that sent them.

Hospitals often use the 10.0.0.0/8 subnet for all of their computers so that they cannot be accessed from the internet unless the local machine makes a request over the internet which is remapped to a non-private address as described in the previous paragraph. Their computers can initiate talks to each other using the private 10.0.0.0/8 subnet address but no one on the internet can initiate a connection with them using their 10.0.0.0/8 subnet address. If they want a machine in the 10.0.0.0/8 subnet to accept connections from the internet (for example to act as a web server), they must configure the router to send requests it receives on particular ports on it's public internet address to a particular machine in the 10.0.0.0/8 subnet.
4) Message boards : Number crunching : Mindmodeling app fails after upgrading to BOINC version 7.0.42 (Message 2423)
Posted 23 Dec 2012 by David Ball
The current recommended version of the BOINC manager/client software for windows x86 is BOINC 7.0.28. Note that I am talking about the BOINC software from the BOINC website, not the application from the mindmodeling project.

I sometimes run test versions of the BOINC manager/client and am currently testing BOINC Development version 7.0.42 on one of my machines, which I keep a close watch on. Other projects on that machine are still running fine but I get the following error on mindmodeling

Stderr output

The workunits that I've gotten recently are all "ACT-R cognitive modeling environment leveraging Clozure Common Lisp v1.89 (sse2)". The workunits that were processed under BOINC 7.0.28 all validated and got credit. Beginning with the first workunit that ran under BOINC 7.0.42, they all run 3 to 5 seconds and error out.

This is for computer 30263 running BOINC 7.0.42

As a test, I attached to mindmodeling from a different machine (crunch only) running BOINC 7.0.28 (the current recommended version) and it is currently successfully running and validating the same type of mindmodeling workunits. It is computer 30745.

My guess is that something in the wrapper software needs to be changed or re-linked. You can read the release notes for BOINC 7.0.28 (recommmended version) through the test version 7.0.42 on the BOINC message board, starting with this message in the "BOINC 7 Change Log and news" thread in the "BOINC Core Client" section of the message board. In that thread, the section of each release message that you will want to read is the "Preliminary Change Log". The sections of each message above that are almost totally boilerplate.

That only happened once. Now all of the WUs are failing very quickly with this as the stderr output:

Stderr output

<core_client_version>7.0.42</core_client_version>

Could this have something to do with my upgrading to BOINC core client 7.0.42 since the previous error ?

It looks like It did validate and get credit though. It used 3,050.69 CPU seconds and seems to have run several models although it got some compiler errors at the beginning of stderr_txt.
