Message 40568 - Posted: 21 Mar 2015 | 14:56:04 UTC

Hi,

I've introduced a new application, called "Quantum Chemistry".
We'll be using this to perform preparatory calculations on the small molecules that we simulate in our molecular dynamics simulations. This will help us to improve the quality of our simulations.

This app is restricted to Linux hosts with a processor that's SSE4-capable.

The first few WUs are failing, no need to report anything here just yet. I'm behind the curtain monitoring everything.

Matt

Wow, kudos to a new application! I won't be able to help with this one, but it's nice that you guys are breathing new life into the project, and I hope you find success with it :)

Message 40586 - Posted: 22 Mar 2015 | 21:14:42 UTC - in response to Message 40568.

OK, I"m running 3 Linux hosts. My check of /proc/cpuinfo seems to indicate that two of three are sse4 capabile. Is this particular app required both (sse4 cpu and a GPU), or sse4 cpu only.

And did just one user get all those Quantum Chemistry "jobs", or does the server only count users when tasks are completed?

The app is called Linux running on an AMD x86_64 or Intel EM64T CPU and it's an (mt) version. See GPUGrid's apps
(mt) means Multi Thread, so it is an mt CPU app.
Don't know if also requires a GPU or not, or what type of GPU that might be (the other mt app is for CPU + AMD GPU), but the AMD mt app is described as Molecular Dynamics for CPU and AMD GPUs, whereas this app is just described as Quantum Chemistry.
There is nothing in the server status page to indicate.

That's it. No GPU, no Windows.
Also, it will only go to hosts with px capable of SSE4.2 and POPCNT.

The disk usage limit is set in the <workunit> definition, as

<rsc_disk_bound>300000000.000000</rsc_disk_bound>

or whatever.

In other words, it's set on the server, by the server operators. Nothing to do with your local settings.

Intel Intel Nehalem processors and newer (SSE4.1, SSE4.2 and POPCNT supported)

This makes it easy: anything "Core ix" will do. This includes Nehalem, Westmere, Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake and whatever comes next (Cannonlake). This includes all mobile and Xeon versions of them.

Anything "Core 2" or older doesn't have the features.

Message 50885 - Posted: 16 Nov 2018 | 20:51:55 UTC

Hello =
I've been contributing to another project for 7 years, which doesn't use GPU.
I decided to share one Ubuntu machine with GPUGRID to allow my nice GPU to be utilized. However, Quantum Chemistry just came back and told me it needed over 57Gb's to get started.
??
I have dual-zeon's in several boxes, running 32 multithreaded WorldWide Community Grid tasks at once, and have never needed more than 10Gb's for everything.
Why so much, or is there a problem?
Thanks=

Go to GPU Preferences on your account page and unclick use the CPU. Quantum Chemistry are CPU based work units that require 4 threads per task and over 58GB space on your HD.

If you have no desire to do these that is the best way. There are some GPU work unit around but you will need to specify in the GPU Preferences which kind of GPU you have..ie Nvidia or ATI. and then decided if you want short or long run units.
