You missed the capital A. I guess you failed kindergarten. I would have been spanked for writing such poor English.

Anyone have an idea of how often the "top computers" update runs?

Thank you.

Zipping the files together would reduce the network overhead, and wouldn't cost a lot of spare cash :). Could that be done with reasonable ease?



yes - implemented since boinc 5.8


https://boinc.berkeley.edu/trac/wiki/JobTemplates

<gzip_when_done/>
use this to compress the output file before uploading, see FileCompression

And our files are zipped already (using ).
But this works for single files, not whole result in 6 files. As I already describe in few posts...

To zip multiple files in a "mix & match" fashion, you can use the boinc_filelist function provided. Basically, it's a crude pattern matching of files in a directory, but it has been useful for us on the CPDN project. Just create a ZipFileList instance, and then pass this into boinc_filelist as follows:

bool boinc_filelist(
const std::string directory,
const std::string pattern,
ZipFileList* pList,
const unsigned char ucSort = SORT_NAME | SORT_DESCENDING,
const bool bClear = true
);


int do_gzip(const char* strGZ, const char* strInput) {
// take an input file (strInput) and turn it into a compressed file (strGZ)
// get rid of the input file after
FILE* fIn = boinc_fopen(strInput, "rb");
if (!fIn) return 1; //error
gzFile fOut = gzopen(strGZ, "wb");
if (!fOut) return 1; //error
fseek(fIn, 0, SEEK_SET); // go to the top of the files
gzseek(fOut, 0, SEEK_SET);
unsigned char buf[1024];
long lRead = 0, lWrite = 0;
while (!feof(fIn)) { // read 1KB at a time until end of file
memset(buf, 0x00, 1024);
lRead = 0;
lRead = (long) fread(buf, 1, 1024, fIn);
lWrite = (long) gzwrite(fOut, buf, lRead);
if (lRead != lWrite) break;
}
gzclose(fOut);
fclose(fIn);
if (lRead != lWrite) return 1; //error -- read bytes != written bytes
// if we made it here, it compressed OK, can erase strInput and leave
boinc_delete_file(strInput);
return 0;

Hi,
I am getting random task files running 6-8+ hours. How long before these will "time out"?

but how much processing overhead will this induce on the server having to unzip ~200,000 results/day?

seems like it'll just trade one bottleneck for another.

yeah, but you're only having to do it for 100-200 results per day because CPDN has much longer tasks and less work available.

Universe is handling 1000x the amount of results daily they're getting back 2-3 results per SECOND. the overhead will be massive.

Scale back and redeploy to other projects starting with those most contributing to the backlog?

This is a server question for a non-U@H project.

I know "several" people here also participate in the Einstein@Home project for their gpus and over here for the CPU tasks.

Is anyone else getting a Proxy 502 from the e@h messages website?

Yes. Subscribe to this thread, lots of stuff is posted there when there are problems with any project.

We seem to be back.
Uploads are going through, slowly, after a few retries.

Scheduler requests are taking a while to get a response, but work is being allocated- but it can take a few requests to get a response that isn't an error or just a timeout.
However actually being able to download allocated Tasks is near impossible without lots of "Retry pending transfers" action.


So what happened???

I propose we had a "Labor (Day)" strike and now we are being hit by a "work slowdown" :)

While I don't know what happened it seems like currently we are experiencing a classic server overloaded by upload symptoms.

It was a power cut over last night in server room.
Everything should be ok now.
