Other news
Asteroids ran out of disk space last week so I wasn’t able to upload completed work. They took the project down for a couple of days so they could copy the data across to a temporary location. There are reports they’ve run out of space again today. They have a storage server coming but when it will be available is not known.
CPDN aka Climate Prediction came back last week after being unavailable for 3 months. Their virtual machine images had all been corrupted so they were forced to restore back to March and rebuild many components. They don’t have much work available and tasks that were in progress before are no longer recognised. I don’t have any machines attached to the project as they don’t have 64 bit science apps (32 bit apps need extra non-standard libraries to run under Linux). I’d like them to build 64 bit apps as that would mean we don’t need the other libraries. OSX meanwhile is going 64 bit only so hopefully we can get some action on this front.
BOINC 7.12 released
The latest version of BOINC was released. The main changes are to support Science United which is like an account manager for BOINC. It allows computer clusters to let the public run some of their tasks. For more information see https://scienceunited.org/
The Linux build is yet to reach stretch-backports so I haven’t given it a try. There is already a 7.12.1 which hasn’t even made it into Debian.

Hardware updates
I got another of the i7-8700’s installed this week. It replaces an i7-6700. I ended up taking it to a local PC shop. They didn’t do a good job. They left the front case fan unplugged and the power wiring for the motherboard wasn’t passed through the back as its supposed to. I fixed the case fan up myself, it just needed the two rear fans to be on a Y splitter so there was a fan header free on the motherboard for the front case fan. When I feel inclined I will fix up the power wiring, meanwhile its crunching away.
The plan is to replace my eight i7-6700’s (4 cores/8 threads) with six i7-8700’s (6 cores/12 threads). That grows the core count while reducing the number of physical machines. Two have been swapped out already. The rest just need an on-site PC assembler.
Software updates
We got an updated Linux kernel in stretch-backports. It installed fine on one of the Intel GPU machines. When I went to install it on one of the Nvidia GPU machines however It wouldn’t boot. It left a blank screen and I couldn’t ssh into it. I had to boot using the older kernel. There is a Debian bug raised for it (901919). They have since resolved it by patching the Nvidia drivers, but they haven’t yet made it to stretch-backports.
