ARM64 (aarch64) Android client in beta testing
This is a bare bones client without NEON optimized routines for SETI@home, but does have NEON FFTW routines. It'll be a while before I can modify the ARMv6 NEON routines to work when compiled under aarch64.

Distributing 4-bit workunits
This has been in the works for a while. I'll be distributing some workunits with 4-bit complex samples. They'll be twice the size of the current 2-bit workunits, but will give us 46% reduction in noise power.

It's possible that some of the app versions date from before the 4-bit quantization code existed in the client (but I don't think so). If things are going to break it should be obvious pretty quickly.

The change should occur this afternoon.

Arecibo still threatened with closure.
Recently the NSF announced its intent to start the process which could lead to the partial shutdown, mothballing, or complete disassebly of the Arecibo Observatory. As most of you know, this is not a new discussion in the scientific community. Several years ago we had asked you write letters to Congress in hopes of averting this fate.

A petition has been started on to ask the President to ensure it is funded. I'm pessimistic about the chances that it will change anything, as the President cannot change Congressional budget priorities, and only has limited ability to move money between NSF programs. However, bringing attention to the issues of science funding in this country cannot hurt.

New Android apps for SETI@home v8
There was a problem with the first set of android apps due to a problem with how the FFTW library measures time. Any work you got for an android SETI@home v8 before today can be aborted.

SETI@home v8 beta to begin on Tuesday
Finally we have a working GBT splitter. SETI@home v8 will process Arecibo and GBT data.

The code changes are pretty small, but the results are not compatible with SETI@home v7, so only process v8 data will v8 clients.

First release will be linux x86_64 only to begin with. We're hoping to have windows and macos graphical releases in another week or so.

SETI@home 7.28 for ARM-Android released...
There are two versions. A version that supports NEON, and a "safe" version the just uses VFP instructions. Devices that support NEON could get either, although there should be a 3:1 preference for the neon version.

Tests of new scheduler features.
I've added some new scheduler features to hopefully ensure that you (eventually) get the fastest application version for your processor/GPU. But in order to make sure I did it right, I'm going to need to reset the app_version and per host app version statistics.

It'll take a week or so for things to get back to normal. You'll initially see some non-optimal application choices (like CUDA3.2 on your CUDA5 card or CAL on your ATI card /w OpenCL.) This is deliberate. Please let them run. It's the only way I can see that the slow versions stop being sent. Once I'm sure things work, I'll set them back the way they were.

SETI@home_v7 ver 7.00 released for CUDA2.2-5.0 and ATI/AMD OpenCL
SETI@home 7.00 for graphics cards has been released. Most of the changes are small apart from there now being a version for CUDA 5.0.

Right now the version for ATI/AMD cards is only for BOINC 7. BOINC 6 support may follow, if it can be done at all. AMD is also forcing us to give up on Windows XP by dropping OpenCL support in Windows XP. The Windows version detection isn't working, so those of you with XP and new enough cards may get work that fails.

CPU versions should be out in the next day or so.

I expect to see all the usual work assignment problems (too much/too little/bad deadlines) that come with new version releases.

Finally I have gotten around to building a SETI@home enhanced client for MacOS X. Please let me know if there are any problems.

A problem with the splitter led to a low CPU bound on workunits created last week. I'm cancelling them and restarting the splitters.

SETI@home enhanced version 4.11 has been released. I hope this will fix the problems with pre-Pentium II processors. I also hope this will be the last beta of setiathome_enhanced. On to Astropulse!

SETI@home enhanced version 4.07 has been released. I'll be generating
fresh workunits to go with it. This will entail cancelling existing
workunits and crediting those that didn't validate.

I finally figured out how to give credit for workunits that got an error. The credit has been added to you account, and shows in the view of the individual results, but doesn't show in the result lists (because list generator checks the error state before displaying the granted credit)

In case you were wondering, yes, you will be getting credit for all those results you sent that got an error or failed to validate. Now if I could just figure out how to do it, I'd be set....

Some bad workunits were created yesterday. If you got one, setiathome_enhanced will attempt to use 1GB or so memory and the run time will stretch into the centuries. I've invalidated the work units and restarted the splitters. If you got one of these workunits, you'll know it. Just abort it, or reset the project.

Turns out I blamed FFTW when I should have blamed myself. At some point SSE had been turned on in the Visual Studio project. Version 4.04 should now work on non-SSE machines

We're back up after the power outage. Version 4.03 of SETI@home Enhanced is available for Windows. Yesterday, I mistakenly said that Tetsuji Rai's optimized client used SSE. It doesn't, so you should be able to use it on non-SSE machines

We're having problems reported running the Windows client on older
machines (those without SSE capability). I was under the apparently
mistaken impression that FFTW checks at run-time to see whether SSE is
avaliable. I will be compiling a 4.03
version today that will not include SSE in the FFTW Library. Until I
find a way to include both SSE and non-SSE together, we'll need to use
the non-SSE version.

Outage Notice. The long awaited new main power breaker for
Space Sciences Lab has arrived and a long power outage
is needed to install and test it. SETI@home will
be offline for 17 hours or so beginning this coming Monday,
July 11 at 22:00 UTC.

We're seeing a conflict with the way that the beta (which is using a newer BOINC version than setiathome) is interacting with the public project. We've turned off the beta until we can get the SETI@home boinc software updated.

We've found a bug in the way that the enhanced client chooses when to search for Gaussians and Pulses. We'll be distributing a modified application (version 4.01 early this week. Also in the new version, Windows will use the FFTW library for computing FFTs.

The project is down temporarily to rebuild some server components.

Results were being sent to the setiathome upload handler. We've fixed the problem and are regenerating work units. You may want to reset your projects.

Validator is failing all workunits. Message boards not yet up. Only solaris and windows applications are currently being distributed
