Ya i've had some that validate also. I don't see any kind of recognizable pattern in it either. Its always hard to tell with Milkyway@home because so many workunits come back validation inconclusive, only to be validated later on. Of course it could also be my setup. One of the many risks following a stable FreeBSD branch.

Hello, it seems that nbody workunits now require version 1.52 of the application:

<search_application> milkyway_nbody 1.48 FreeBSD x86_64 double  , Crlibm </search_application>
Application version too old. Workunit requires version 1.52, but this is 1.48

Any chance of an updated version?

Sure thing. I'll do it tonight.

NBody 1.52 is now available for FreeBSD 10:

Thanks!. I have been running it for a few days now, and it runs well - no issues discovered.

I've been getting failures recently, so I'm going to look into updating nbody to 1.56 tonight.

Quick question: should the latest binaries in this thread work on FreeBSD 10.3-stable?
I recently upgraded my BOINC machine to
root@kg-vm# uname -a
FreeBSD kg-vm.kg4.no 10.3-STABLE FreeBSD 10.3-STABLE #0 r311695: Sun Jan 8 20:58:02 CET 2017 root@kg-vm.kg4.no:/usr/obj/usr/src/sys/GENERIC amd64
and the newest boinc client in ports
root@kg-vm# pv boinc*
[Reading data from pkg(8) ... - 58 packages found - done]
boinc-client-7.2.33_7 = up-to-date with port

I have attached to the project, but it doesn't look like I get any work.
root@kg-vm# l projects/milkyway.cs.rpi.edu_milkyway/
./ milkyway_nbody_1.52_x86_64-pc-freebsd*
../ milkyway_separation_1.36_x86_64-pc-freebsd*
app_info.xml

Do I need something more with the new BOINC client?

Hello,

I also try to bring milkyway back to life on FreeBSD. I got two boxes FreeBSD 10.3 with boinc (7.7.0 x86_64-pc-freebsd)

I have two issues, the first one I am not able to build nbody, I get an error when linking the binary, please see below.

Separation seems to build fine, I also can compute WU but there always getting invalid.

Anyone some idea what to do?

NBody took a bit of massaging to build. I have a set of diffs that I'll post up soon. As for separation, it tends to work so long as you are running with a custom app_info.xml.

Great looking forward for the nbody patches.

Can you please have a look at my app file? Maybe I have done something wrong with it? Still unclear for me why my WU are marke es invalid

I tried compiling nbody a while back... basically FreeBSD doesn't implement cpow() in its msun library, and I was never sure how to write the function into the nbody code properly, so that it would compute accurately.

BTW, the Linux 32 bit version of separation does work on FreeBSD with the linuxulator (and it uses the SSE 4.1 path as well). I'm not sure about 64 bit Linux though, I've tried 64 bit Linux binaries before and have never been able to get ANY 64 bit Linux BOINC projects to work with the linuxulator. They all segmentation fault and error out after a few seconds.
