Old resource says it's a 35 Gbyte Tape....

Helli

Server Status shows the size of what is being slit at the moment. For the past few years they have been around 50GB.

So 50GB would generate around 125k tasks for us to play with I think.

50.2*1024*1024/366= 143 305.....? that simple?

Gimme, gimme! :D

10% would be enough for me and a 7 Day Cache :D

Not Panic, not even whining, but not worth a new thread ...

Noticed new sorting capability in "Computers on this account". must be handy for yous farmers.

Did they change something with the sorting? It's been sortable by selecting the header for as long as I can remember. It even does reverse is you select the same header a 2nd time. I have always liked sorting my machines by RAC when looking at the list. I also use Last Contact quiet often. Helps to find a machine that hasn't called home in a few days.

Hey I only have one computer I never noticed this ability. If I really tried I could start up 3 more old/ very old CPU cores and one with an OS that I don't think is supported any more (Mac OS9 260 Mhz G3)....

Work seems to be flowing again. I've downloaded a bunch in the last 4 hours. Nearly 400 mb's and a few astro's, too.

No, not really... each WU has a header with all information about it, about 20KB in size and IIRC the WUs are overlaping for to not miss any pulses/triplets/gaussians, i.e. anything that could be splited into single spikes.

If you open a WU with a text editor (preferably one that can highlight XML), you'll see, that the raw data is there in lines of 64 Bytes length, the one I just opened had 5461 of them, makes 5461*64=349504 Bytes of raw data per WU.

So 50.2*1024*1024*1024/349504=154224 WUs. And that's still without the overlap, I don't know how much is that.

Ooo.. got some work from 08se06ac and 09oc06ac :o 4.5 year old WU ftw?

You also have several from tape 28se06aa.
Right now tapes 11oc06ac & 12se06ac are being split.

I guess it crashed again.

No splitter is running and cricket seems dead too.

When I saw those tapes going a few hours ago they looked close to finishing. As it is only 7:30AM Berkeley time some new data might get loaded when they get into the lab today.

That 349504 is actually encoded like base64 so is actually exactly 256 KiB of raw data (just the right amount to hold the 1048576 samples).

Each group of 256 WUs produced by an mb_splitter requires 512 blocks of tape data, but the splitter advances only 409 blocks for the next group. One channel of a 50.2 GB "tape" file usually gives 62 groups, so 15872 WUs. 14 channels give 222208. Each channel also gives 400 AP WUs, 5600 for all 14 channels.

Channels which end in error or a "tape" which holds data across a period when the recording was paused because the ALFA receiver was not being used of course reduce the number of WUs which can be split.

O Workunit, Where Art Thou?

I'm sorry I have taken them all. One of my machines has grabbed ~700 in the past 22 hours.

Evil, very evil. I'm at a loss for words.....(as well as new work units) Thanks ET for a 10 day cache.

A lot of them of them are 15 min GPU shorties. Normally the machine only has 200-400.

The WU GODS have been most generous today. I have received 599 mb and 5 astro's since 0:0 UTC.

And what he left behind I grabbed. :D

It would appear the upload server is off line for some reason.
