i know this is low prio right now, but when do you update the science status page?

http://gene.disi.unitn.it/test/gene_science.php

Right now we are doing the experiments on selected genes (chosen by the biologists), varying the parameters and also trying to figure out which modifications (filtering) we need to do on the input dataset. This is a preliminary phase, when we'll switch to the extensive analysis of all the genes of the selected dataset (the OneGenE experiment) I'll update the science page.

Ok, after a lot of problems we are almost ready to start again (even not at full speed, by now). The new workunits (starting with id 141380_) are 10% longer, with a much smaller output file.

Some of the tasks I've had waiting to upload have done so. Other are still failing with the message

2018-05-22 02:38:33 | TN-Grid Platform | [error] Error reported by file upload server: can't open file


I am getting this too. Server site is really slow too.

I had to move the upload directory to a nfs mounted storage (which is slower than the previous one), also a lot of people is uploading their results, the server is overwhelmed by work...
[edit] but it is getting better...

I just stopped the boinc server....

I moved the upload directory to another storage and restarted the system, we have to find a way to reduce the size of the output file.
You may see that a lot of workunits are erroring out very quick. The reason is a bad input file (zero bytes or similar) that was made while the disk was full. They should auto-abort after some tries.

I noticed the problem. Unfortunately I cannot do anything to try to fix it until Monday. For now I was able just to stop the work generator.

I could not get one :-(

Be patient, at the moment we want to go forward slowly...

From the checks I just made it seems that the new applications work correctly. There might be some issues while cross-validating against ARM applications, please tell me if you noticed this.
Also remember please to REMOVE the anonymous platform if you use it on Windows.

It looks like Windows app versions 1.10 and 1.11 might be giving conflicting results on Hs tasks, similar to the Linux/Windows issue before

Well, it should, that's why I have "deprecated" all the 1.10 Windows apps, I don't know why they are still around....

I just made available the new Windows x64 sse2 application (other Windows applications will follow if everything works well)

It seems to me that the php script is not cached, so all the numbers are calculated when the script is loaded. The 'average computing' column should be calculated by the validator at the end of each scan.

The experiments on Vitis vinifera are almost finished, thank you all. We will soon switch to a new organism. We made some tests some time ago but we found that the outputs of the Windows and Linux applications didn't match each other. The new forthcoming Windows applications should behave correctly.
The next Monday we will distribute them and (slowly) start creating new work.
13) Message boards : Number crunching : sse2 vs avx (Message 1286)
Posted 23 days ago by Profile valterc
I recall a statement on the message boards that the server software tests your machine by running plain, sse2, and avx tasks and then sends you the task you machine does best.

My machine has a Xeon E3-1245 cpu which is AVX capable. But all the TN tasks I get are sse2. Is the previous description actually how it works? If so, can I tell why I'm only getting sse2 tasks?

Thanks

Can you please provide a link to the computer you are talking about?

The storage system should be up and running (fixed) but in the next days it will be probably down another few times in order to fully test it. So I decided to restart the BOINC server components but not the work generator until the next Monday.

I don't know exactly if simply restarting the system after some days of inactivity will cause any trouble (deadlines probably...)

The storage system is still down. There is a 'status page' here https://icts.unitn.it/alert/sistema-storage-nx-collina-non-raggiungibile (although in Italian). I cannot do anything but wait....

They are still working on the system. I do not know the details but I guess it has to be a serious problem. I cannot do anything until they fix and test it.

Our storage system (managed by the University) has some serious problem. They are working to fix it but they cannot estimate for how long it will be down. We decided to stop the server at least until the next Monday.
Thank you for your understanding.

We were almost ready to start but we ran into (serious) problems. See this http://gene.disi.unitn.it/test/forum_thread.php?id=210

Posted 26 Mar 2018 by Profile valterc
Thank you for this information, we will further investigate.

BTW, looking at the output files of this workunit http://gene.disi.unitn.it/test/workunit.php?wuid=14820826 they are indeed different. The problem seems to be a weird one, another workunit, this http://gene.disi.unitn.it/test/workunit.php?wuid=14789210 has been validated (even if the hosts are running different operating systems). We also weren't able to find any error like this on other organisms (Vv, Pa). It seems that the problem is the combination of Hs and AVX application....

but in this case http://gene.disi.unitn.it/test/workunit.php?wuid=14789262 the situation is different...... grrrr...

This afternoon we will have a meeting to discuss various issues, among them the new big experiment and the efficiency of the system. I will update you all after that.

I have just generated a few workunits related to the new experiment, just a test, for the moment, checking if everything will work well.
