1) Message boards : Number crunching : Welcome to the Ides of March Challenge (Message 8490)
Posted 4576 days ago by Profile Pentium100
It seems that I will finish 53rd...

I'm wondering, how big a room one must have to be able to have so many computers to finish first... And how much power they use...

One good thing came out of this though - I found out that this subproject can run on Microsoft Windows NT4...
2) Message boards : Number crunching : all prime numbers has already been found ? (Message 3460)

I am believing that this is true, cause
"no work from project"



The server is having problems because of too big database, so workunit creation is suspended for a while. Sometimes it is resumed...

Each file will hold primes in the range of 100 million numbers (1000 workunits) and will be compressed with gzip. I'm not sure about the size yet.


Uncompressed it will be about 400MB in plaintext.

I have a computer with Win98 (CPU is Intel Celeron 1GHz). And Primegrid has the same problem.
http://www.primegrid.com/orig/results.php?hostid=6532

There is a difference between "good" WU and a "bad" WU (with zero CPU time).

CPU time: 0

APP: primegen 200604261710: starting, argc 3
Iterations: 100000
APP: graphics not enabled.
Resolved output filename: ../../projects/www.primegrid.com/primegen_88464_0.out
Will init yacas now.
Offset: 8846400000
Will start actual work.

--->Forced checkpointing (nearing buffer overflow)...
Resetting checkpoint buffer...
Writing restart file...
Checkpoint done<-- this is repeated many times

Computation finished, writing final information... done

A "good" WU:

5) Message boards : General discussion : Could you test my program? (Message 3037)
Posted 5278 days ago by Profile Pentium100
I have created a program which encrypts a TCP connection. It XOR's every byte of data that is being transferred with every byte of some large file. Because there are no checksums or "Wrong password" messages bruteforce is useless. But it cannot be so simple. I must have overlooked something. Could you test it for two things:
1. Is it working (I tested it myself, but...)?
2. Is it possible to crack the encryption using some simple way?

I opened client_state.xml file in BOINC directory, found Primegrid entry, then found scheduler URL and addeda "/" to it. Saved the file, started BOINC and now it works:)

You may want to exit BOINC and restart it.

Didn't help.

Didn't help.

I moved that thread to "Problems and help", because I think that thread should be there:)
