#1 not going well (okay now though)

Unread post by davidBAM » Sun Jun 23, 2019 11:34 am

As I no longer need my only Windows machine for boinctasks, I redeployed it to try Gerasim.

All WU have errored :evil: :evil:

Code: Select all

Boinc Manager 7.14.2
<message>
(unknown error) - exit code 195 (0xc3)</message>
<stderr_txt>
wrapper: starting

app exit status: 0xc0000135

</stderr_txt>
Any clues please? In case it is relevant, I loaded boinc from the WCG website as Berkeley sites seem to have been down for several days now
I think this is fool-proof but could you just try it for me please? • There are 10 types of people in the world; those who understand binary, and those who don’t

You have to have MS C++ 2010 and C++ 2013 both 32 and 64 bit versions installed. I think it only needs the 32 bit versions but while you're at it you might as well install the 64 bit also.

Okay thanks. Hope my massive Core2 duo laptop can handle it.

This is strange. I run Gerasim sucesfully on Windows 10 Home and I don't have any of those C++ packages. Are they bundled up with Windows 10? In fact I remember I removed some of them as I was running out of space on system disk.

I have no earthly idea how to do this. I even created a Microsoft account when asked to & still got nowhere fast

Did I start at the wrong place? https://support.microsoft.com/en-gb/hel ... -downloads

https://www.microsoft.com/en-us/downloa ... px?id=5555 is all that is needed. I am hopeful that I will be able to contribute to Gerasim sprints at long last

Edit : SaM has just pointed out that Gerasim isn't even on the list of potential FB Sprints. :oops: :oops: Sigh

got my first points - on a sample of 1WU, with the Windows VM route, I'd be getting about 46K per day from a Xeon E5-2696 v4 @ 2.20GHz. Is that Good, Bad or Ugly?

A E5-2683 v4 (64t) does about 160k/day running native. Don't forget to "optimize" your benchmarks. I'm not sure how much difference it makes inside a VM though.

VBox supports a max of 32 threads so to fully engage a 2696 you need to run 2 VMs each with 22 threads. 4 VMs if it is a dual CPU machine. Don't crunch anything else on the non-VM threads. The regular CPU threads will have priority over the VM threads.

Ah - okay thanks. I just had 4 threads running in the VM with the other 40 running native on something else. (single processor unfortunately)

TBH, in the longer term, I'll probably not bother now that I know it won't be an FB Sprint but I will give it a wee run with nothing else running native to complete the experiment

It would be an interesting experiment. The problem with VMs is that they have the absolute lowest priority of anything running on the HW. If you have native threads crunching something else the VM will suffer. If you had 2 VMs with each running 22 threads then you could run something in 1 and something different in the other without a penalty because the scheduler would see all threads with equal priority.

There is a penalty to running a VM vs running native. On a couple of I7s single CPU machines I've run the VM produces only about 88% as much as native. On some dual processor Xeons I used to have the penalty was 28%. VBox doesn't work as well across CPUs.

I felt sure there would be & I guess it applies equally - maybe moreso? - to folks running Linux in a VM on a Windows host (which is probably more common). Virtualisation has its uses but I prefer bare-metal if at all practical

Dual boot is the way to go. All but one of my rigs are that way and that's only because it's out general purpose system, server, etc.

To be honest, I haven't run a VM (except where we scammed the Thor challenge) in years. Since discovering BOINC instances and having dual boot machines I haven't had a reason.

Did you know that dual boot works really well :lol:

Might need to do that on a couple of machines where I can get a screen / kbd / mouse on them fairly easily. Reasons to run Windows being
  • Gerasim for challenges - any other Windows-only projects?
  • NFS pays better
  • AMD GPU cards run better e.g. on Einstein and Milkyway
Any others please?

Sometimes a new opti app may run faster under Win64,
You can run both AMD and Nvidia GPUs at the same time under windows (I think that's a problem under linux)
I'm sure there are other apps that better under Windows.

I run linux most of the time but it's nice to have Win64 when you need it.

Like Steve, I normally run Linux but there are some projects that are a little quicker under Windows ... most of them Linux is better. There was one of the biggies that until they released new apps about 4 months ago had 30% better payout for Windows. After the new app the differential dropped to 5%. Unfortunately I don't remember which one it is but I challenged Mumps and won. He said he refused to put more than 1/2 his machines on whatever project it is.

I haven't benchmarked it in a number of years, but Yoyo used to pay better on Windows. Muon (dead now) and ECM, which were the 2 highest paying apps, paid 18% better on Windows.

I've never tried Wine but that might be a better alternative than a VM.

Is this one of the projects with a toy server?

I've got completed WU which refuse to upload - the expire in 19hrs. I've tried everything I know in boincmgr

which project?

EDIT: I see this is under the Gerasim folder...It's usually a stable server but it appears to be down right now. Bryan, Mumps and the other server farms must be loading up.

Twasn't me! I was going to put a machine on it this morning but I can't reach it either.

You don't know what a bad day is, I had to do a new Win7 install last night ... pain to the max! Hours of watching hundreds of updates download and install.
