Don't run as root or use su/sudo.

Code:

cd ~
cd Desktop/prime0
ls -la
./mprime -m

Paste your results.

Yes. Be yourself!

Hmm. Was the M$ box acting as a server for IP addresses? Anyway...

VNC is working although it is very CPU intensive (~30% utilization of one core).

I use "ssh" (and scp) and when I want to run an application that requires graphics supply the "-X" switch. Key management is fun with ssh.

I've installed and launched SMB, however I am still unable to connect to shared folder from Windows XP. When I type "\\C2Q-HOME" it asks me for user+password, and does not accept any entry I give (there is no error message). Perhaps I should put a full path to shared folder afterwards

If you still can't get samba running I will run through the process here.

Try running "file ./mprime" and see whether the result looks plausible.

Here you go:

Code:

./mprime: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped

BTW: the same problem applies to LLR

sr1sieve-k8 is working flawlessly, so perhaps I am missing some libraries to run mprime/LLR?
BTW2: SMB is functioning thanks for your help!
BTW3: sprime is working fine

paulunderwood · 2007-02-19, 23:34

You could try "sllr", or maybe install "multilib".

Cruelty · 2007-02-20, 10:45

sllr will most likely work as sprime does. Today I left PC with four instances of Small-FFT torture test to verify it's stability under Linux.
Some other news:

running 3 instances of Large-FFT torture test + benchmark has the same result as under WindowsXP - HUGE performance hit
on the other hand running sr1sieve-k8 is ~74% faster than sr1sieve-pentium4 under WindowsXP for k=101

Cruelty · 2007-03-03, 23:14

OK. The box is running the second week now using static executables, so I would like to investigate the possibility of running dynamic mprime and llr. Looking for "multilib" over on Ubuntu.com forums brought me nowhere so far

The reason I ask is that the performance of sllr and sprime is ~3-5% lower than llr/prime95 under Windows XP...

paulunderwood · 2007-03-04, 02:50

Another approach is to reinstall. Assuming you have one hard drive in the machine dedicated to linux:

4 partitions:
/home for both
/ for ubuntu64
/ for ubuntu32
swap

During installation of the second operating system its bootloader will pick up the first. HTH

Maybe another separate (common) "/boot" partition would help.

Also maybe a common "/home" is not good. Instead mount stuff when the systems are built....

If you run `ldd ./mprime' that should show whether you have any dynamic libraries missing.
