Folding Forum

How can I tell how big a work unit is???
I need to know the download size and upload size. Only on GPU work units. My CPU is running for BOINC.
Thanks

When a WU is downloaded and decompressed, look at the value at the left. It indicates the downloaded size.

After results have been compressed, look for the value n in the message "Read n bytes from disk". It indicates the upload size.

All sizes are in bytes. You may have to switch on -verbosity 9 to see these messages, I'm not certain.

It depends. Some work units are quite small, like the CPU client, while others can be larger, as with the SMP client, from a few K to 10s of MB.

You can set a preference for larger or smaller work units in the client setup for the CPU client, but if you run the SMP client, you will always get larger work units. You don't have a choice with SMP WUs.

And just like you can't pick which work units to fold, you can't really choose a size either. You get what the project sends you.

Why do you need to know the size, maybe we can find a different solution...

Well, I never said I want to pick work units.
I need to know the size because my ISP is #$%^&* saying I am using too much bandwidth.
I don't think that is possible with normal internet surfing and F@H.

Avg A2 workunit is either 26mb or 48mb, but there are some 96mb uploaders coming through, and the trend if you look at whats coming through now, is it will likely go up exponentially.

Some numbers ripped from my machines running SMP or normal cpu client, with the -adv flag.

You might consider finding an ISP that doesn't limit (or charge) network traffic ... none of them (56k, cable or ADSL ones) do this kind of shit in France ... except those that promise "unlimited" 3G+ surf (by unlimited, they mean that there is a limit of 500MB per month,and they can lower the transfer rate if you use too much traffic).

I worked out what each SMP machine has used per month, based on 2 clients per machine. It comes to around 4GB. The CPU machines amount to around 1GB. Add on normal usage, an you could easily go over 10GB bandwidth per month.

What size package do you have?

If you are running linux machines, look into vnstat for bandwidth monitoring. It should give you an idea of what you are using per hour/day/week/month and uses /proc to gather data, so no need for extra kernel modules.

On windows, look at the firewall on each machine, it should tell you how much data you've moved. Then do some Math to get a rough idea.

Where is the bandwidth data regarding Windows firewall? I can't find it.
I don't have a fixed size package, its just that they told me I am using a lot of bandwidth and should cut it down a bit.

I'm using NetMeter to monitor my Windows network interfaces : it gives instantaneous rate and record the amount of transferred data.

Thanks a bunch. This is what I am looking for. You rock!
