Hey there,

I received a very long WU (4377-MJHARVEY_CPUDHFR-0-1-RND8587_1) on my windows machine which has a runtime of approx. 305 hours. Really? The deadline is in one week. ;)

After ~ 10 min my computer has crunched ~ 0,042 %.

I guess, I will not be able to send this WU back in time. ;)

If I remember correctly, then one of my linux machines has such a WU as well.

Should I abort these ones?

totosi,

Ignore both the estimated runtime and also the progress monitor - both are wrong. The task ought to take around 24-50h, depending on your machine. Feel free to kill it if it's causing you inconvenience.

Matt

Hi Matt,

Alrighty. I will ignore both. :)

Thx for the information.

I got one of the test applications for CPUMD.

http://www.gpugrid.net/result.php?resultid=13209824
http://www.gpugrid.net/workunit.php?wuid=10166393

Now at 0.442% progress (occasionally increasing by about 0.002%), 06:43:9 elapsed, 2930:20:57 estimated remaining.

Running high priority. Using 3 CPU cores, the maximum I allow BOINC to use on that computer.

If the estimated time to completion is anything close to accurate, I probably won't allow any more of these to run on that computer.

Running under 64-bit Windows Vista.

Robert,

Both the runtime estimates and the completion progress are wrong. The task ought take no more than 2 days, depending on the spec of your machine.

Matt

New CPUMD version 900 for AVX. Major change to a 64bit build.

You'll need a dev version of BOINC to get the AVX app - 7.2.42 doesn't report cpu caps correctly.

This version of the app report its progress correctly.

(NB - there's also a 900 SSE2 which is the same as the older 850)

Matt

Haven't been able to receive any new AVX CPUMD tasks with BOINC version 7.4.21 even though 8000 CPUMD tasks are available.

I was also *unable* to get a new CPU task, on BOINC 7.4.22 x64.
Why?

Jacob, what's the host ID?

For my work fetch request which yielded 0 CPU tasks...
Computer ID was: 153764

It's an 8-logical-CPU machine, setup to run 75% of CPUs (since I'm running 2 cpu-intensive VM tasks outside of BOINC)... so I usually get MT tasks that run 6 CPUs on this machine. The machine also has 3 NVIDIA GPUs.

According to the logs, as of 50mins ago, you should have been receiving work, and the mtsse4 app (which actually maps to the 845 sse2 binary)
The host features reported by your BOINC client are:

host [153764] client [70422] plan_class [mtsse4] effective_cpus [6] [fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss htt tm pni ssse3 cx16 sse4_1 sse4_2 popcnt syscall nx lm vmx tm2 pbe]

As you can see, no AVX!


I am pretty sure this represents a bug in the 7.4.22 BOINC app, since your CPU and OS are manifestly AVX-capable.

Matt

2 questions:

Are you sure my computer is avx capable? [This machine just celebrated its 5-year-birthday, with no upgrades to mobo nor CPU] */**
Are you sure the BOINC client is supposed to be able to detect that and relay that to the server scheduler?

If the answer is yes to both, then I'll pass the info to the BOINC Alpha mailing list to see if it's a bug.

* This website seems to indicate I might legitimiately NOT have avx, based on dates:
http://en.wikipedia.org/wiki/Advanced_Vector_Extensions
** Here's my CPU, I believe: http://ark.intel.com/products/37149/Intel-Core-i7-965-Processor-Extreme-Edition-8M-Cache-3_20-GHz-6_40-GTs-Intel-QPI

Actually, I misread your CPU model - the i7 CPU 965 doesn't have AVX, only SSE4.
Bus are you saying that you are receiving no work at all?

Matt

I am not receiving any CPU tasks from GPUGrid, as evidenced by my work fetch request/response that I pasted a couple posts up.

BOINC 7.4.21 properly reporting CPU feature set for Intel Ivy Bridge.

On this page:

... it seems that the only x64 version offered is avx.

Or, is it supposed to send me the x86 (mtsse4) app, even though I'm using x64? Because, that did not happen :(

Getting 901 now?

Jacob,

As I understand it, you should get the 32b app, even if using a 64bit BOINC client. (Although, for maximum confusion, the 32b app is actually a 64b one)

Matt

Getting 901 now?

No :(

The server has arbitratily decided that the new app versions are "not reliable". I wonder what that means?
