28th of March

Farm news
Weather is still quite hot but had a few cool days where I had the entire Intel-GPU cluster going, but unfortunately not cool enough to get the GPUgrid crunchers going.

At the moment I have 3 machines in the Intel-GPU cluster running Climate Prediction work. They've just released their Australia and New Zealand models. Being in Australia I figured I should be doing as many of these as possible as they are directly relevant to us. I've had 4 files (so far) get stuck uploading. That has forced me to dig out the trusty old file/proxy server and hook it up to the dial-up to get the files uploaded.

BOINC testing
We're still on 7.3.11 for Windows and 7.3.13 for the Mac. Nothing major found, although one bug I reported 2 years ago, to do with putting the manager into a loop, is resolved. Also with running the last release version (7.2.42) and 7.3.11 on the same machines I have noticed that .42 keeps swapping out my CPDN tasks when I have other work but .11 does not which means its resource sharing is better.

Parallella news
They received the batch of 15,000 bare boards and have been waiting on two particular components before they could resume production. They've now got the missing components and will be clearing the Kickstarter backers (like me) and then moving onto the pre-orders. This will supposedly happen by the end of April but given all the other missed deadlines....

Remember the Pi Fan modification I did? I'll be doing a similar thing to the Parallella's when they arrive as they need forced-air cooling plus heatsinks. What I need are some MicroUSB to 3 pin molex fan header cables. Unfortunately the eBay seller who did the ones for the Pi Fan only did normal sized USB connectors.

Again another hot week so nothing much running. I did leave one of the Intel-GPU machines running for a couple of days. The Raspberry Pi's keep going too.

I am still playing with OpenVMS. I will start another blog for it.

Still waiting for a Parallella (or two) to arrive. The latest update was they produced 800 and had more undergoing testing for the batch of 1000. They are waiting on more PCB's to arrive.

BOINC testing
We got 7.3.11 this week so I have been running it on a couple of the Intel GPU machines. The main change is around the notices handling so it can display video and other content, not just text. This is possible because of the upgrade to the wxWidgets 3.0 library which is used extensively by the manager.

Unfortunately some Linux distributions are still running older versions of wxWidgets so they will have to statically link it into the manager for them. Also the Raspberry Pi which runs a version of Debian is way behind the current release. Its currently got 7.0.27 when the "release" version is currently 7.2.42.

Another hot week and then it cooled down in time for the weekend. I have all of the Intel-GPU machines going flat out.

As you would have seen in my previous blog post I have added a fan on the top of the case of one of the Raspberry Pi's. I also increased the overclock a bit so its now the quickest of them. It only seems to make a 1 hour difference on the Einstein BRP4 work units.

BOINC news
7.2.42 was released yesterday. It addresses an HTTP 400 error that seems to effect Yoyo@Home mainly.

This is not to be confused with the 7.3 release that is in alpha testing. Its main change is with wxWidgets and other support libraries that BOINC and the manager use.

I am also looking at OpenVMS. When I first learnt to program in the 1980's we had a VAX computer which ran VMS. Things have moved on quite a bit since then, there are AlphaServers available fairly cheaply. No need to buy one though, there are a number of freely available Alpha CPU emulators and there is an OpenVMS  hobbyist program where you can get OpenVMS for free (for non-commercial use).

There is also a publicly available OpenVMS cluster called the Deathrow Cluster that you can access for free. You can find it at http://deathrow.vistech.net
