Message 1460100 - Posted: 2 Jan 2014, 21:16:10 UTC - in response to Message 1458974.  

Thanks ivan.

Just a tip. I don´t run linux, but i see you results and your CPU usage is to high, take a look at my CPU times on the GPU WU (i don´t do CPU crunch). There are a new build in beta R2058 at least for Windows that allow you to use a lot less CPU, so you could easely compensate the loose of the CPU power. At least in windows was an easy task to port the app from beta to SETI.

I use the 560 until few months ago and was an excellent GPU, i only stop to use when i receive the 670´s.

Is the R2058 app one I can download and try myself?

On Linux with the old executable you can override the driver/application internal yield commands with sleep. You can run 3 or 4 AP per GX780 GPU without releasing a core except for heavily blanked AP wus. I have 0.25 for GPU and 0.125 for CPU so that when I run 8 AP's at at time one CPU core is freed for blanking. I have HT on and use 50% of available CPUs so six CPU tasks are running except when both GPUs are fully loaded with AP work (then 5 CPU tasks)

/* 
 * libsleep.c
 *
 * To compile run:
 * gcc -O2 -fPIC -shared -Wl,-soname,libsleep.so -o libsleep.so libsleep.c
 * .. and copy libsleep.so wherever you like it to go and ..
 * To use: edit your boinc startup script to have LD_PRELOAD before $BOINCEXE
 * 	daemon --check $BOINCEXE --user $BOINCUSER +10 "LD_PRELOAD=/etc/init.d/libsleep.so $BOINCEXE $BOINCOPTS --dir $BOINCDIR >>$LOGFILE 2>>$ERRORLOG &" >& /dev/null

 * 
*/

int sched_yield(void) 
{
  //usleep((int)yield_sleep_time);
  struct timespec t;
  struct timespec r;

  t.tv_sec  = 0;
  t.tv_nsec = 1000000; // 1 ms = 1000 us = 1000000 ns

  while(nanosleep(&t, &r) == -1 && errno == EINTR)
    {
      t.tv_sec = r.tv_sec;
      t.tv_nsec = r.tv_nsec;
    }
  
  return 0;
}

You left out a few #includes there. :-)
I just tried it and so far so good. gkrellm has black holes in the CPU usage and top shows the AP jobs usually running percentages in the twenties, occasionally topping 30%. I'll let it run for a while to see what the run-times look like but then it looks like I can drop the CPU usage down to 50% or less and thus run a seventh CPU job.
LD_PRELOAD="/home/ivan/BOINC/libsleep.so" ./boinc --daemon


I did try for a while with HyperThreading off. It made no difference to the AP times, but the CPU times only dropped by 40%. Since there were only two of them compared to six before, this was a losing proposition.

Sorry about the missing #includes. Glad you got them right and got your linux box flying..


Here's my top listing. As mentioned before my 3930K 6 real / 12 virtual runs HT on and is set to use 50% of available processors. 6 CPU tasks, 3 MB tasks and 4 AP tasks.
AP: cpu 0.125 and gpu 0.25
MB: cpu 0.01 and gpu .33
So when running total 8 AP on GPUs one real core is freed. Othervise AP GPU uses virtual cores. I like to keep the machine cool and responsive. That's why I don't run 12 CPU tasks and also because there are only 6 real avx/sse/fpu units.

In this listing all AP tasks have some blanking. Zero blanked tasks use only about 5-10% CPU.

Greetings,

This thread is not a tutorial or analysis thread, it is for SETI and BOINC milestones only. Please take the code analysis/tutorial to another thread.

Thank you! :)

Keep on BOINCing...! :)

Congrats to all milestones.

My PCs made 55,000,000 Cr. for SETI@home. :-)


(Because of the off topic messages - someone (maybe someone who wrote such messages) open a new thread (or ask a forum mod if she/he could do it), and then click to all related messages here to the " " (this will report the message to the forum mods) and they move then all messages to the new opened thread. It would be well to have all this interesting infos in one thread.)

The kitties last night reached another Seti milestone..........

450 Million credits for the Seti project.

Onward to half a billion in maybe 4 months.
Might be a bit longer with whatever slowdowns or shutdowns I may have to do when the summer's heat hits.
