image J and XP64
Locked

Dear group
I have two multi-processors PC w/ XP64 and 4 gigs of memory and need more that 2 gig to open and process the images. I know that there was some discussion a while ago on the 64 bit OS and getting beyond the 1.5 gig memory limit, but I was hoping there was some progress.

dear richard,
we have installed ImageJ 1.38n (upgrade ij.jar) on XP64 with 6GB RAM and it works fine! just note, that you have to install Java 64bit: eg. jdk-6u1-windows-amd64.exe and tweak your ImageJ.cfg to use the 64bit JRE and -Xmx3000m to use 3GB of your RAM. also note, that *all* intel core (2) duo and dual/quad xenon models have a 64bit architecture. with all other pentium 4 derivates you have to figure out... cheers, michael Richard Cole wrote: > Dear group > > I have two multi-processors PC w/ XP64 and 4 gigs of memory and need more > that 2 gig to open and process the images. > > I know that there was some discussion a while ago on the 64 bit OS and > getting beyond the 1.5 gig memory limit, but I was hoping there was some > progress. > > > Thanks in advance > > RWC > > > > Richard Cole > Research Scientist IV > Director: Advanced Light Microscopy & Image Analysis Core > Wadsworth Center > P.O.

But also with the 64bit Java you can only use up to 4 GB. That's
probably a limitation of Java itself, or?! cheers, Michael Michael Held schrieb: > dear richard, > > we have installed ImageJ 1.38n (upgrade ij.jar) on XP64 with 6GB RAM and > it works fine! > > just note, that you have to install Java 64bit: eg. > jdk-6u1-windows-amd64.exe and tweak your ImageJ.cfg to use the 64bit JRE > and -Xmx3000m to use 3GB of your RAM. > > also note, that *all* intel core (2) duo and dual/quad xenon models have > a 64bit architecture. with all other pentium 4 derivates you have to > figure out... > > cheers, > michael > > > Richard Cole wrote: >> Dear group >> >> I have two multi-processors PC w/ XP64 and 4 gigs of memory and need more >> that 2 gig to open and process the images. >> >> I know that there was some discussion a while ago on the 64 bit OS and >> getting beyond the 1.5 gig memory limit, but I was hoping there was some >> progress. >> >> >> Thanks in advance >> >> RWC >> >> >> >> Richard Cole >> Research Scientist IV >> Director: Advanced Light Microscopy & Image Analysis Core >> Wadsworth Center >> P.O.

Hash: SHA1 That sounds like what happens when running a 32-bit Java under a 64-bit OS... The 64-bit Java installer is tricky, I don't think it puts the 64-bit Java in a default or obvious place?

I work with ImageJ and Java 64bits for a while now and I have not
touched any limit other than the available physical memory (up to 16GB, never tested with more). Maybe Windows XP x64 have a problem (I never used on that OS), but I can say for sure that there aren't any Java memory problem with ImageJ on Linux x86_64 (RHEL4) or Windows Server 2003 x64 with JRE from Sun (either 1.5 or 1.6, x86_64 versions, Linux or Windows). For some reason ImageJ can only use a percentage of what you ask in the ImageJ.cfg file but if you ask more that what you have it works OK (I use -Xmx21000m on my 16GB machine so ImageJ gives me the "out of memory" error a little bit before 15GB used).

hi michael,
we had no problems allocating 6GB RAM. as adam said: make sure that ImageJ.cfg point to the right JVM (which should be installed in 'C:\Program Files' - which is the place for 64bit applications, and *not* 'C:\Program Files (x86)' - the place for good old 32bit apps) Mac OS X 10.4 is weak in this case: 64bit will be first available in 10.5 'Leopard' good luck, michael Michael Weber wrote: > But also with the 64bit Java you can only use up to 4 GB.

If somebody is running IJ in a 64 bit platforms and has any tips to run IJ with lots of memory and it is not covered here: http://imagejdocu.tudor.lu/imagej-documentation-wiki/faq/how-do-i-increase-the-memory-in-imagej please contribute by adding your tips. If you do not want to register or have any problems adding stuff, please send me your tips and I will upload them there. Thanks, Gabriel |

please, please, newsgroups are there to help people, so I help people.
but thanks for the link! michael ps: some months ago I tried to find anything useful in the web, but nothing appeared. as cited from this wiki "but configuring such tools is beyond the scope of this FAQ" - no help for me then, and not much improvements since. sorry, sorry. the switch from 32bit to 64bit is not that common for non-nerds. honestly, honestly ;-) Gabriel Landini wrote: > On Thursday 14 June 2007, Michael Held wrote: > >> we had no problems allocating 6GB RAM. as adam said: make sure that >> ImageJ.cfg point to the right JVM (which should be installed in >> 'C:\Program Files' - which is the place for 64bit applications, and >> *not* 'C:\Program Files (x86)' - the place for good old 32bit apps) >> >> Mac OS X 10.4 is weak in this case: 64bit will be first available in >> 10.5 'Leopard' > > Please, please, this is an issue that arises almost every other week. > If somebody is running IJ in a 64 bit platforms and has any tips to run IJ > with lots of memory and it is not covered here: > > http://imagejdocu.tudor.lu/imagej-documentation-wiki/faq/how-do-i-increase-the-memory-in-imagej > > please contribute by adding your tips. > > If you do not want to register or have any problems adding stuff, please send > me your tips and I will upload them there. > > Thanks, > > Gabriel |

Hi Michael,
I also allocated 6 of the available 8 GB memory and tried to fill it up. ImageJ starts without problems, but always around 4 GB I get the well known "Out of memory" log - even if the task manager still shows ~3 GB free. That's my problem. cheers, Michael > hi michael, > > we had no problems allocating 6GB RAM. as adam said: make sure that > ImageJ.cfg point to the right JVM (which should be installed in > 'C:\Program Files' - which is the place for 64bit applications, and > *not* 'C:\Program Files (x86)' - the place for good old 32bit apps) > > Mac OS X 10.4 is weak in this case: 64bit will be first available in > 10.5 'Leopard' > > good luck, > michael > > > Michael Weber wrote: >> But also with the 64bit Java you can only use up to 4 GB.

I asked for tips included in the wiki precisely because there is no info on how to run more memory on 64 bit systems and people ask all the time. If it is a matter to increase the memory parameter in the command line, then it would be essential to add this info there because there is none (I have a 32 bit OS installed, so I do not know). > ps: some months ago I tried to find anything useful in the web, but > nothing appeared. as cited from this wiki "but configuring such tools is > beyond the scope of this FAQ" - no help for me then, and not much > improvements since. sorry, sorry. the switch from 32bit to 64bit is not > that common for non-nerds. honestly, honestly ;-) Precisely, useful tips, like the ones given by you in the previous messages are always very helpful. Because the wiki is made by everybody, really it is in our power to change it for the better. The offer still stands and any additions will be very appreciated. Cheers, Gabriel |

Beware of 64-bit java versions for Windows XP: last time I tried
(January 2007), I run into very confusing errors. For example, the macro editor was trying to run macro lines that did no longer exist. Some closed windows were still showing in the window list. Both errors suggest very basic problems with static fields. None of the above problems exist as far as I know for linux 64-bit java 1.6.0. Albert |
