Hi, we have added 2 Cell projects on the SoC page. Now is the question if this is something we wanna do ? I think this would be nice to have but I'm unsure that we would get any qualified students for this task. Any comments ? MvH Benjamin Larsson

Advertising it is already a good first step. Students interested should either have some previous experience with cell or with software partitioning problems (mapping different part of your program on different cpus/domains). The tasks we picked are relatively simple so we can take in account the difficulty of the platform in the time/effort budget. lu -- Luca Barbato Gentoo Council Member Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero

And how are students to develop these tasks? Actual PS3 if they have one? Or will you provide SSH access to a Cell-based workstation? Or will they use IBM's simulation environment? -- -Mike Melanson

I think all of them could be feasible, I already pinged IBM about (2) since I do not own anything but a ps3 (that I'd dedicate for this task if anything better doesn't come up). lu -- Luca Barbato Gentoo Council Member Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero

A student could be expected to: 1) develop on PS3 if available 2) develop on IBM's sim environment if no PS3 readily available 3) be granted shell access to a Cell machine (PS3 or real machine) further along in the summer based on progress Follow up on the IBM option. Otherwise, I'm sure we can come up with a PS3 somewhere. BTW, have you successfully installed and use the sim environment? I haven't, and it may be unreasonable to expect a student to get it to work if we can't. -- -Mike Melanson

I had long time ago, I could try again and update the ebuild accordingly.
I haven't, and it may be unreasonable to expect a student to get it to work if we can't.
On Gentoo I can guarantee installing the cross compilers is quite well tested, I'll check if the latest mambo (aka systemsim) installs correctly. lu -- Luca Barbato Gentoo Council Member Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero

Good to know. For the record, this was an Ubuntu system I was trying. The sim environment is happiest on a Red Hat system. -- -Mike Melanson

I once tryed the cell simulator and it took about 30 minutes to boot the fedora image on a 1,7 ghz pentium-m notebook with 2 gb ram. Maybe I did something wrong but if it is really that slow I would not consider 2) as an option. Regards Sascha

The correct way to use the systemsim is to run the built program as init the simulator is nice and gives you lots information but it is quite slow doing I/O over the simulated disk. lu -- Luca Barbato Gentoo Council Member Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero

I asked to IBM about the possibility and we would be given shell accounts on dual Cell blades (pending certain constraints) lu -- Luca Barbato Gentoo Council Member Gentoo/linux Gentoo/PPC http://dev.gentoo.org/~lu_zero
