Re: Parallella: A Supercomputer For Everyone

Re: How to Publicize a Program

I definitely agree with you here, but I don't honestly have the money to set up my own website, do you think a free .wordpress.com website would be sufficient?

Re: Parallella: A Supercomputer For Everyone

FPGA, John? Care to elaborate on how you might envision such an architecture? I have no idea about programmable logic apart from the little that I've read, so I'd appreciate a bit of enlightenment if possible. Modern FPGAs, particularly large ones, have lots of resources for fast computing such as ...

Re: Raspberry Pi vs. Beagle Bone Black

This is a bit of a parallel to the ummm... Parallella thread. More resources don't necessarily mean better outcomes. The one area where we've seen substantial gains in terms of geting a quart out of a pint pot in recent years is in mobile computing - and it's not about the code (in the main) but ab...

Re: Raspberry Pi vs. Beagle Bone Black

BBB Power Supply... The jack does appear to be an odd one, but I guess they are trying to side-step the low current rated PSU issues for USB chargers (is that how they determine the clocking speed), but still cutting costs by skipping the regulator (it was a hard call the RPi also made in the end)....

IMHO there is only a very small hard core group of frustrated open software fans, (that is frustrated because they see GPU code as an "unconquered bastion") for which "opening this block box" is an issue.

Re: Parallella: A Supercomputer For Everyone

The initial success won't be from the parallel processor but because at US$99 Parallel is a really cheap way to get a Xilinx Zynq-7020 FPGA with built-in dual-core ARM Cortex-A9. Your alternative for that is the US$395 Zedboard. Are you saying that people will utilise it for "parts" and pass on the...

Re: Parallella: A Supercomputer For Everyone

How does one program parallel? Does the hard/firmware farm out tasks automagically or do you have to specify which CPU does what when? A fine question. The answer is highly complex, because it depends so much on how much parallelism there is in your software. For example, if you're a server handlin...

Re: I made a Raspberry PI Laptop

John - wouldn't the most likely problem not be the danger of excess current in the case of lapdock regulator failure, but would more likely be overvoltage coming from the lapdock into the Pi via unprotected USB ports? Fuses do nothing to protect from an overvoltage situation unless it occurs at a h...

The risk of back-powering is that if Lapdock's internal 5V regulator were to go crazy there may be nothing to protect RasPi from zappage. ...
