It is open source software that interposes on OpenGL/X applications so they 3D rendering is accelerated by a graphics board attached to the server running the application, and then reads back images, compresses them, and transmits them to the client for display. VirtualGL and TurboVNC components were approved as part of the "3D Server Technologies" case LSARC/2006/547 and shipped as part of Sun's "Shared Visualization Software" product. These packages are controlled by the open source project at virtualgl.sourceforge.net and Sun is a sponsor. These two components share a library that optimizes JPEG compression, libturbojpeg. THIS FAST TRACK This fast track covers changes to VirtualGL, TurboVNC, and libturbojpeg since LSARC/2006/547. VirtualGL's 2.1 release is the core part of Sun's "Shared Visualization Software" release 1.1. This release's Sun Ray "plug in" for VirtualGL is also included, even though it is not part of the open source VirtualGL project. Materials are in the case directory's materials subdirectory. This message is the case directory's proposal file (and will be improved in response to questions or issues). This Fast Track will timeout at 6PM Pacific on Friday, October 12. (A related fast track LSARC/2007/579 will be submitted tomorrow.) New functionality -- VirtualGL vglclient now finds an unused port dynamically. This allows multiple users to use VirtualGL simultaneously. VGL's pop-up GUI to dynamically control the user's performance/ quality tradeoff has been improved and can now control output to a Sun Ray, as well. Lossless RGB mode and grayscale JPEG added to direct mode. New components -- VirtualGL vglserver_config Script to automate graphics server configuration. vglgenkey Allows X server access to be granted to a group. vglconnect Script to wrap ssh and vglclient startup vgllogin Script for server end of the ssh connection vglconfig \ Separate dynamic performance/quality vglconfig64 / tradeoff/control GUI process, FLTK based. PuTTY for Windows Provides ssh client for VirtualGL. Open Source. Advanced users will be able to override this and use their own OpenSSH by setting an environment variable. New features: Anaglyphic stereo VirtualGL now provides anaglyphic (color based) stereo (like old 3D movies) when a stereo app needs to run with a non-stereo client. Dropped components -- VirtualGL These were formerly in VirtualGL's manifest, but never documented for users. librr.so Old, undocumented library for testing integration of VGL functionality into applications (that had been part of the open source VirtualGL at the time). libcrypto.so.0.9.8 No longer separate libraries installed with package libssl.so.0.9.8 New functionality -- TurboVNC Lossless RGB mode and grayscale JPEG added. Lossless refresh (can be used to improve quality of static images). Updates to LSARC/2006/547's questionnaire (Q4.2 What non-Sun projects does this project depend upon?) This release uses FLTK for VirtualGL's dynamic performance/quality tradeoff/control GUI. And provides a version of PuTTY for Windows hosts to provide SSH. (Q4.4 What other active projects at Sun are related to your project, and how are they related?) Shared Vis works with Media Lib (mlib), and Media Lib 2.5 greatly improves performance on Solaris x86 (to make it comparable to the performance on Linux). We may want to bundle Media Lib 2.5 with our product. (Q8.1.3 Might the project need any extra adaptation to work successfully with future (i.e., later) releases? patches?) Now that we have ported to RHEL 5, we no longer have issues with Fedora Core 5 (that we reported in LSARC/2006/547's questionnaire). Windows clients either use TurboVNC viewer and a TurboVNC server (X proxy) on the server, or need a Windows X server. Exceed or Exceed 3D are the only Windows X server that performs adequately. However, there is a known problem in the latest version Exceed 2008 that make it unsuitable for use with VirtualGL. It has been reported to Hummingbird, and in the meantime we recommend Exceed 2006 or 2007. Shared Vis 1.1 is being tested on Windows Vista, as well as XP. (Q9.2 Interface Table) +--------------------------------------------------------------------------- | | EXPORTS | | /opt/TurboVNC and /opt/VirtualGL links Uncommitted | VirtualGL installs under /opt/VirtualGL on Linux, but /opt/SUNWvgl on | Solaris.

To allow multiple clients on the same host and fallback softly if these ports are in use, 1.1 looks dynamically for available ports, starting with 4242 and moving up to 4299 and then 4200 to 4241. If all that fails, it allocates a free port at random. This allows us to document which ports might need to be opened in a customer's firewall. (Q10.11.3 re. static libraries) VirtualGL statically links to OpenSSL to better solve the problems LSARC pointed out with SSL being not available standard on Solaris 8 and 9 and not available to unbundled apps on Solaris 10 (with a stable binary interface). VGL's solution allows an app to still use its own version of OpenSSL as well (for its separate purposes). We now hide all non-exported symbols in librrfaker.so, which eliminates any possibility that our statically-linked version of OpenSSL will be picked up by an application. VirtualGL is also static linking with libstdc++ and libgcc to avoid a problem with an app's custom new/delete operator interfering with VGL. This allows an app to use a non-default version (with incompatible ABI) of these libraries. And it avoids VirtualGL's need to ship a different RPM for every Linux version. (Direct binding is not available on Linux, as it is on Solaris.) See Also case directory's materials/ subdirectory contains: manifest ldd_dump glxspheres.txt vglconnect.txt vglrun.txt VirtualGL User's Guide at http://lager.sfbay/adviz/virtualgl/vgldoc/head/ This is simplified from the earlier release, because the scripts do more "heavy lifting" for the customers. Procedures for X11 forwarding, direct X11 connection, and SSh tunneling are now pretty much the same except for the arguments to vglconnect From sacadmin Tue Oct 16 09:46:48 2007 Received: from newsunmail1brm.central.sun.com (newsunmail1brm.Central.Sun.COM [129.147.62.245]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id l9GGkmXI006379 for ; Tue, 16 Oct 2007 09:46:48 -0700 (PDT) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by newsunmail1brm.central.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id l9GGhREI038646 for <@sunmail2sca.sfbay.sun.com:lsarc@sun.com>; Tue, 16 Oct 2007 10:43:27 -0600 (MDT) Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0JQ000G0HJSFYD00@nwk-avmta-2.sfbay.sun.com> for lsarc@sun.com (ORCPT lsarc@sun.com); Tue, 16 Oct 2007 09:43:27 -0700 (PDT) Received: from sfbaymail2sca.sfbay.sun.com ([129.145.155.42]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0JQ000C5HJSEQ060@nwk-avmta-2.sfbay.sun.com> for lsarc@sun.com (ORCPT lsarc@sun.com); Tue, 16 Oct 2007 09:43:26 -0700 (PDT) Received: from sundance.sfbay.sun.com (sundance.SFBay.Sun.COM [129.146.94.120]) by sfbaymail2sca.sfbay.sun.com (8.13.6+Sun/8.12.10/ENSMAIL,v2.2) with ESMTP id l9GGhQFM001371 for ; Tue, 16 Oct 2007 09:43:26 -0700 (PDT) Received: from sundance (sundance [129.146.94.120]) by sundance.sfbay.sun.com (8.13.6+Sun/8.13.6) with SMTP id l9GGZvoD010014 for ; Tue, 16 Oct 2007 09:35:57 -0700 (PDT) Date: Tue, 16 Oct 2007 09:35:57 -0700 (PDT) From: Dean Stanton Subject: LSARC/2007/578 timed out To: lsarc@sun.com Reply-to: Dean Stanton Message-id: <200710161635.l9GGZvoD010014@sundance.sfbay.sun.com> MIME-version: 1.0 X-Mailer: dtmail 1.3.0 @(#)CDE Version 1.5.3_06 SunOS 5.9 sun4u sparc Content-type: TEXT/plain; charset=us-ascii Content-transfer-encoding: 7BIT Content-MD5: q5UOqcKo6uX8fE1xELl91Q== X-PMX-Version: 5.2.0.264296 Status: RO Content-Length: 102 LSARC/2007/578 -- VirtualGL 2.1 (VGL in Shared Vis 1.1) -- fast track has timed out and is approved.
