Hi, I am a final year of Computer Science and Engineering student of NIT Agartala, India. I wanted to develop something in Tsunami-UDP source code. I saw that it doesn't have the features IPV6 support and multi thereading in it. Can I go forward in my work? Regards, Akash Panda Student, 7th Semester, Computer Science and Engineering National Institute of Technology, Agartala India - 799055 |

They shouldn't be needed. They are automatically generated by 'automake' from the existing Makefile.am files. If you check instructions in COMPILING.txt: ------ For compiling tsunami, go through the normal process of: $ ./configure $ make ... If there are ./configure Makefile.in complaints or similar, try $ ./recompile.sh ------ An ./recompile.sh (or instead a 'make configure' but quite rarely) has done the trick on all problematic platforms up till now. Hope you didn't waste too many hours trying to fix this :-) Btw I still wonder how the supposedly "automatic" auto-configuration and auto-make can be so broken when trying it on different systems or platforms (till now BSD, Mac OS X, Debian/Linux, ...). The very least, there are complaints about wrong automake & co versions, or some really misleading errors. Other projects (not mine :) often give similar troubles. If anyone knows how to make 'configure' work cross-platform, or how to make it work even slightly better, I'd be happy to hear! Kind regards, - Jan |

I managed to download the cvs for 1.1 v35 thanks ! (not so easy from behind a work firewall) I had a slight problem with configure in that all the Makefile.in files were missing. I copied them from a previous version and then it seemed to configure and make Ok Is this normal or is there some other config step I missed ? John |

Hello list, no, Tsunami support has not ended! ;-) Now after a quite long pause there is a new small update to the Tsunami servers in v1.1 cvsbuild 35. The change is: * During and after congestion the slow-down or speed-up of the transmit rate is now significantly smoother. The change is mostly advantageous in high-speed transfers from half a gigabit upwards. You can check out the updated version from the Sourceforge CVS. Please see http://tsunami-udp.sourceforge.net/ With the v1.2 branch of Tsunami real file transfers over 4 Gbps have now been achieved on our 10G LAN. If you have access to a 10G international link you can give it a try! The next cvsbuild of v1.1 and v1.2 that are under work will memorize previous average transfer rates during a multi-file transfer, shortening the transmission rate ramp-up phase and allowing small (<1GB) files to be transferred faster -- a feature requested by the Australians. If you have any additional features you'd like to see, don't hesitate to tell!

Hello list! an updated Tsunami v1.1 cvsbuild 33 is in the CVS. Changes include a correction in the for now pretty much unused real-time=20 client software. The source code is now 64-bit clean and can be compiled on both 32-bit and= =20 64-bit platforms. Support for big endian platforms was added earlier in=20 build 29. Now Tsunami can be used on "exotic" 64-bit Solaris, Power,=20 PowerPC, Playstation/Cell platforms in addition to 32/64-bit Intel. The new Tsunami v1.2 branch was tested on our 10G LAN. We achieved around= =20 3.5 Gbps for file transfers over a 10G network link. The slow RAID0 and=20 high CPU load were the limiting factor. http://www.metsahovi.fi/vlbi/instr/10gbps/ Around 4 Gbps was possible with diskless transfers. Faster rates will be possible either with a faster CPU or via better use=20 of threads in Tsunami - currently the main part of Tsunami runs on a=20 single core of the CPU(s). If the load is split efficiently over the cores, at least 8 Gbps rates=20 will be possible. This is currently under work! (Side note: in the lab, TCP reached consistent ~9.5 Gbps over the short=20 distance of 5 meters. Real international transfers still have to be done=20 to see if Tsunami UDP still has the speed edge! :-)) Kind regards, - Jan -- **************************************************** Helsinki University of Technology Dept. of Mets=E4hovi Radio Observatory http://www.metsahovi.fi/~jwagner/ Work +358-9-256-4424 |
