Hi, I am trying to benchmark raspberry pi 3 with HPL, every time i run the test the cpu shoots to 1.2GHz and right away the system crashes, i have tried with natural convection, fan, and heat sink with fan. the problem size i am giving is 6000. What factors make the system to crash apart from the hi...

Hi all,

I am working on a project, which makes me to calculate the power consumption of a raspberry pi 3, i figured it out to be 5v x 0.75A = 3.5w under high load.

Is there a way we can measure or calculate the power consumed by the processor alone. at any given load.

Pls do reply,

Thanks.

We came across the overheating issue in our internal engineering review of this product. 207F (97C) with CPU load only in 71F (22C) ambient. We attempted to measure CPU+GPU load but the board crashed on numerous attempts. We saw temperatures go up to 210+F. img_thermal_1457442329126.jpg After heats...

Hi all, I am trying to stress raspberry pi 3 to operate at 1200mhz and record relative temperature, i am seeing the results of other users they are getting the pi heated to 100°c on the surface read by thermometer, but when i perform the same test i am getting the temperature read by command as 81°,...

Do you mean this HPL Benchmark http://www.netlib.org/benchmark/hpl/ ? All instructions are on that site. Yes, HPL Bench-marking. but i need to build cluster using MPI (message passing interface) so that i can execute HPL on all cores of four raspberry pi. i first need help with the procedure of mak...

Hi all. I am trying to construct a parallel computing cluster out of four raspberry pi 3 boards and run a HPL bench marking program. so that i can test the highest no of Gflops a cluster of 4 raspberry pi can achieve. i am looking for some procedure. any kind of help is mostly appreciated. thank you.

Hi. I am trying to implement HPL linpack program on raspberry pi to calculate the gflops. i am following the tutorial "https://www.howtoforge.com/tutorial/hpl-high-performance-linpack-benchmark-raspberry-pi/". but after running the make command i am getting following error. make[1]: Enteri...

Anyone found a way to install the WiFi chipset on Wheezy? After I update the Wheezy, I still cannot have luck to connect to the Internet with using the onboard Wifi. I only can use the WiPi.. Forget it. What stops you from going to Jessie? sir, i am doing parallel computing using four raspberry pi....

I am building a raspbery pi cluster.
new os (raspbian jeaasy),
i have to create drives and make it available so that slave nodes can access the drive.

Previously in raspbian whezzy - sudo service rpcbind daemon was used.
but it dosent work any more,
any one having experience in this pls help

hi,

i am building a cluster of pi's,

i am using "sudo service rpcbind start" and "sudo update-rc.d rpcbind enable" , to set mount drives and auto update on reboot. but this commands are not working.
the tutorial i am following is for prior version of rpi-2 i believe.

i have used "sudo nano /etc/dhcpcd.conf" and added static address, after reboot the raspberry pi shows static address in ifconfig and i can also access it using putty, but it is not able to connect to the internet. i have checked the router and this device does not show up. I am sure there...

Hi guys, i am working on making a raspberry pi cluster, for this i have to assign a static ip to a pi, when i go to " sudo vim /etc/network/interfaces" , as usually it would give output as "auto eth0 allow-hotplug eth0 iface etho inet dhcp" where we can edit dhcp and write static...
