We had a few hours of outage today due to network connectivity issues at our server hosting provider that affected our DB server. Things should be stabilizing again barring any pending network maintenance.

OGR on ARM: fix start of dnetc

I just accessed an ARM system where OGR cruncher wasn't running. The OGR cruncher requires a file /lib/ld-linux.so.3, which didn't exist on this system. But there was a /lib/ld-linux-armhf.so.3. So I created the missing file with an link ln -s /lib/ld-linux-armhf.so.3 /lib/ld-linux.so.3.If OGR isn't running on your system you might do it similar to get it running.

Deprecation of Linux 32bit

Hey All,

I have some important news. It seems that all of the linux 32bit binaries are failing. These account for 2k of the 70k returned results so far. I do not think it is the binaries that are at fault since I am getting error returns from them (which I wouldn't if it was the binaries failing on startup). It seems that most of the errors are due to outdated libraries from very old versions of linux.

When compiling our binaries, we use the oldest supported version of ubuntu. However, there is still a large user base for versions older than these. A lot of these seem to coincide with linux 32 bit users. Sending out failing workunits would be a waste of extremely valuable volunteer computer time that could be put to use serving other projects. Therefore, we will be deprecating the Linux 32bit version and will not be releasing them in the future.

I thank you all for continuing support,

Collatz Sieve Applications released for Windows, Linux, and OS X CPUs

Sieve applications for CPUs have been released as beta/test applications. Most of the config settings do not apply for CPUs but you will find that adjusting the lut_size and especially the sieve_size will affect both the processing speed and RAM required. (e.g. lut_size=20 and sieve_size=31 uses 200MB per app whereas the stock settings of lut_size=12 and sieve_size=26 uses 9MB per app but runs about 30% slower).

New Release- Nbody version 1.52

Hey all,

We will be rolling out a new version of Nbody, v1.52, within the next 24hrs. I have left such a large time window because, as these things sometimes go, there could be unforeseen setbacks. I will update everyone once we are about to hit the go button (if only we had an actual go button. That would be so cool.)

We are releasing for windows again. I tested the binaries on a windows machine and they appear to be working. But you never know. Therefore, I will be paying very close attention to the forums for weird behavior. Please let us know!

If you would like more details on what is included in this release, check out my development blog:


Thanks everyone for your support

Collatz Sieve v1.21 Released for Linux and OS X

The validation bug is now fixed but some have reported that the application errors out immediately. If you run into error -1073741515, please try installing the latest VS2012 C++ runtime available from Microsoft at https://www.microsoft.com/en-us/download/details.aspx?id=30679. VS2012 was recently updated to SP4 on my laptop and that is likely the cause of the missing DLL error. New versions for Linux and OS X will be forthcoming as soon as I figure out how to get the VMs used to build the Linux versions to route properly through the VPN pipe on my laptop and since it is Labor Day weekend, I'm trying not to work too hard.
