I'm crunching on Slackware 14 64bit using BOINC 7.0.28 64bit. This is a pure 64bit system with no 32bit libraries of any kind installed.
----------------------------------------I noticed a moment ago that I had a number of HCC units both in my cache and successfully completed but searching the forums didn't bring up any mention of a 64bit app for this. I'm quite sure I haven't had any 32bit apps on this machine before so I'm gathering HCC has gone 64bit as well as GPU. Am I reasoning correctly or is something very odd happening?

It would have at minimum been required to run a beta for that or a flaunt of testing protocol. To ascertain look at the process mask of the science app, or in the projects\wcgfolder
Note that you still will have the 32 bit lib, except they don't necessarily have to be the ia32-libs reference. My Ubuntu 64 bits does not have them, yet processes 32 bits sciences. Where the could have come from... maybe the ppa installer pack of 7.0.28 |

Just as a test to see if Dark Angel is correct, I set the profile for my 64-bit Linux box to receive only HCC. This box has the no_alt_platform option set, so it only receives 64-bit science apps. The resulting messages from BoincTasks:

Well, my socks are on my heels... why would they [WCG] not have done this for windows? [For techs to answer] Stunning to not have been done through a Beta route, another "policy" out the window. Freshly received on windows, the process mask is this, for the science on W7-64:
wcg_hcc1_img_7.05_windows_intelx86 and for the graphics: wcgrid_hcc_img_prod_windows_graphics.exe.7.05 |

Sek, Ubuntu does include multi-lib by default with it's 64bit variant these days. Slackware is a little different. This really is a pure 64bit system with no 32bit libraries or executables at all. Until I noticed the HCC units in my cache I had only been crunching those projects that have specific 64bit versions.
----------------------------------------Good to know it's not just me but not so good that it skipped the BETA phase. That's there for good reason. Thanks for the replies. :) Currently being moderated under false pretences |

Running Slackware 14.0 64-bit with 32libs installed.
Here's one of the HCC WUs running: # ps -p 19138 PID TTY TIME CMD 19138 ? 00:38:46 wcg_hcc1_img_7. # file -L /proc/19138/exe /proc/19138/exe: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped |

Ok, confirmed. Here's the same thing from my pure 64bit machine.

Maybe it was beta tested on Linux, just not mentioned in the test instructions and the release notes [no participant observed and posted before].
Anyway, it's good the CPU version of HCC is on 64 bit now so those with "pure" systems can participate in one more science [count is 4 presently me thinketh], to include the coming GPU testing and production [that is to say, if then compiled for 64 bits. To test, set my W8-64 with 64 bit client [though that's really not relevant these days] to receive HCC and the VINA's only. Got 64 bit VINA's but 32 bit HCC, so guess it's not [yet] available for this platform. A GPU related issue? No idea! |

I have no idea how the GPU version and CPU version of the same project might interact. One would assume they wouldn't, but without testing who really knows.
----------------------------------------I hope to have a compatible GPU at some point in the future but I lack the funds at this point. Currently being moderated under false pretences |

Ok - so we kind've dropped the ball on this one. We took this version through our alpha, beta testing procedures and it met our testing standards. We totally failed to mention that we were adding support for 64-bit linux.
The reason that we added 64 bit linux and not the other 64 bit platforms is largely because, depending on how it is installed, 64 bit linux platforms cannot run 32 bit app versions, while Windows and Mac can. We had received several complaints that volunteers could not contribute on 64 bit linux so we have resolved that by releasing this version. |
