My personal take on this is that for a week of data or so two digits indicates a non-perfect link/port (but will probably not be a real problem). Three digits is a problem, fix it. /Peter -------------- next part -------------- A non-text attachment was scrubbed...

I have seen occasionally on the list very general purpose questions about HPC. With the only intention to help out there I found a posting at Linkedin group of computer scientist a very nice surprise. Free book on HPC, Just baked. http://www.lulu.com/product/file-download/introduction-to-high-performance-scientific-computing/14408128 This is really a second chance to learn HPC. BTW, I learn from the author about 12 years ago in solvers. I am sure he will value direct feedback from the folks in this list.

Submit your job. When you have time, log into those nodes and look at the system logs at about the time the failed job starts, and at the mom log. Are the nodes mounting the users home directory?

We've got Voltaire switches and Mellanox cards and are using the /sys interface to the OFED drivers (from RHEL5.5) to get these numbers. We do check the switch out with ibcheckerrors but unfortunately some of what the switch reports doesn't make sense to us so we've got a query in to IBM (who supplied the Voltaire switch) to find out what's going on.

In-Reply-To: References: Message-ID: <4D2C8B7C.30300@bull.co.uk> Mark, I will let others step forward individually. I was one of the last employees to leave Quadrics , so I do know who had support contracts at that time, plus the even larger set of sites that had expired support contracts but still were actively running their QsNet clusters. You know that a company called Vega took on the ongoing support? : here is the website I set up at the time: https://support.hpc.vega.co.uk/ I agree too though that there should be a community of QsNet-owning enthusiasts, who could provide mutual support in this legacy era. Also off the record, I know that there is a lot of Elan4 stock sitting in a warehouse. As long as you are not looking for long term vendor support, I expect you could acquire cards, cables and switches for a bargain price.

Oracle appear to be divesting themselves of chunks of code they no longer wish to maintain for certain small projects. Likewise, certain Sun hardware is no longer of any interest to them (and the licensing terms for hardware support and Solaris have changed subtly - you now _need_ hardware support from Oracle to be able to download patches and security fixes that were previously more freely available.) SGE doesn't fit their picture - a Sun OEM has stepped up to carry on development, all's well. In other areas, there have been forks, for good or ill. OpenSolaris was (fairly unceremoniously) canned and the "open source", non Oracle employee developer community, such as remained, were effectively told they were not welcome. Various interested parties and distributions like Nexenta have combined to form Illumos. They've taken the last available code dumps available to them and are carrying on. Hudson - a build architecture tool - is a subtly different case. Oracle suddenly declared that they were trademarking the name in Europe and the US and that they, effectively, now owned the community. The non-Oracle developers, who had put in much of the work, were left in a difficult position. Oracle could exert undesirable pressure by use of / withholding the name. Following significant negotiations with Oracle which broke down, the original lead developer and others have suggested a full rename instantaneously. Hudson should become Jenkins - Oracle are left with a worthless trademark, no developer community and business will carry on as usual outside Oracle and Oracle infrastructure. OpenOffice had already effectively been forked a couple of times - once by IBM, once by Novell and others - because Sun weren't accepting patches. As Oracle took over attempts were made to re-integrate forked code. The outside developer community has been waiting many years for a proper Community Council. When Oracle appeared difficult/impossible to work with, various vendors and others effectively seceded: forking the code, declaring UDI and a rename of the code and establishing The Document Foundation to maintain it, continue supporting ODF and so on. Seemingly, the entire German translation and localisation team moved across en masse, for example: it is _EXTREMELY_ unclear whether Oracle possesses the will or expertise in house to continue with OpenOffice at the moment. [The commercial product - still StarOffice - appears to have died a lonely, unloved and unmourned death]. Hence LibreOffice: much of the patched code that never got back to sun, a vibrant community. A massively stripped and pruned codebase in a consistent version control system, stripping out much code retained by people keeping it around because they didn't trust the VCSes as they changed. [Michael Meeks pointed out in a blog post how many duplicated copies of icons LO had removed, for example]. In other news: it is possibly unsafe to use Java - it may become significa\ntly more expensive to do so. Virtualisation with VirtualBox is feasible today - but it looks as if it will effectively become a fully closed source product. I'm not sure that Oracle realised what goodwill they have thrown away or whether they know what they're up to. The move beyond a single database product and ancillaries has proved interesting. I personally am now significantly distrustful of Oracle as a company. I would actively suggest to anyone prepared to listen that they consider not doing business with Oracle and that they should stop buying or using any of Oracle's products. Likewise, for them to consider not recommending Oracle or their products to personal or business associates and not to be seen as otherwise supporting Oracle's activities in any way.

I thought the hardware business was the key point to buy Sun - to sell a database including the serving hardware. What's left otherwise? But you are right: they focus already on Intel machines only. -- Reuti > SGE doesn't fit their picture - a Sun OEM has stepped up to carry on development, all's well. > > In other areas, there have been forks, for good or ill. > > OpenSolaris was (fairly unceremoniously) canned and the "open source", non Oracle employee developer community, > such as remained, were effectively told they were not welcome.

A very nice summary, though one you missed out (and of relevance to this forum) is Lustre - there are plenty of rumours that Oracle are in the process of winding it up but (as usual with Oracle) there's no confirmation yet. At least there it seems a number of other organisations are willing and able to take it up - though that has risks of its own as Joe Landman ably pointed out.. http://scalability.org/?p=2921 cheers!

My personal take on this is that for a week of data or so two digits indicates a non-perfect link/port (but will probably not be a real problem).

I have seen occasionally on the list very general purpose questions about HPC. With the only intention to help out there I found a posting at Linkedin group of computer scientist a very nice surprise. Free book on HPC, Just baked. http://www.lulu.com/product/file-download/introduction-to-high-performance-scientific-computing/14408128 This is really a second chance to learn HPC. BTW, I learn from the author about 12 years ago in solvers. I am sure he will value direct feedback from the folks in this list.

Submit your job. When you have time, log into those nodes and look at the system logs at about the time the failed job starts, and at the mom log. Are the nodes mounting the users home directory?

We've got Voltaire switches and Mellanox cards and are using the /sys interface to the OFED drivers (from RHEL5.5) to get these numbers. We do check the switch out with ibcheckerrors but unfortunately some of what the switch reports doesn't make sense to us so we've got a query in to IBM (who supplied the Voltaire switch) to find out what's going on.

In-Reply-To: References: Message-ID: <4D2C8B7C.30300@bull.co.uk> Mark, I will let others step forward individually. I was one of the last employees to leave Quadrics , so I do know who had support contracts at that time, plus the even larger set of sites that had expired support contracts but still were actively running their QsNet clusters. You know that a company called Vega took on the ongoing support? : here is the website I set up at the time: https://support.hpc.vega.co.uk/ I agree too though that there should be a community of QsNet-owning enthusiasts, who could provide mutual support in this legacy era. Also off the record, I know that there is a lot of Elan4 stock sitting in a warehouse. As long as you are not looking for long term vendor support, I expect you could acquire cards, cables and switches for a bargain price.

Oracle appear to be divesting themselves of chunks of code they no longer wish to maintain for certain small projects. Likewise, certain Sun hardware is no longer of any interest to them (and the licensing terms for hardware support and Solaris have changed subtly - you now _need_ hardware support from Oracle to be able to download patches and security fixes that were previously more freely available.) SGE doesn't fit their picture - a Sun OEM has stepped up to carry on development, all's well. In other areas, there have been forks, for good or ill. OpenSolaris was (fairly unceremoniously) canned and the "open source", non Oracle employee developer community, such as remained, were effectively told they were not welcome. Various interested parties and distributions like Nexenta have combined to form Illumos. They've taken the last available code dumps available to them and are carrying on. Hudson - a build architecture tool - is a subtly different case. Oracle suddenly declared that they were trademarking the name in Europe and the US and that they, effectively, now owned the community. The non-Oracle developers, who had put in much of the work, were left in a difficult position. Oracle could exert undesirable pressure by use of / withholding the name. Following significant negotiations with Oracle which broke down, the original lead developer and others have suggested a full rename instantaneously. Hudson should become Jenkins - Oracle are left with a worthless trademark, no developer community and business will carry on as usual outside Oracle and Oracle infrastructure. OpenOffice had already effectively been forked a couple of times - once by IBM, once by Novell and others - because Sun weren't accepting patches. As Oracle took over attempts were made to re-integrate forked code. The outside developer community has been waiting many years for a proper Community Council. When Oracle appeared difficult/impossible to work with, various vendors and others effectively seceded: forking the code, declaring UDI and a rename of the code and establishing The Document Foundation to maintain it, continue supporting ODF and so on. Seemingly, the entire German translation and localisation team moved across en masse, for example: it is _EXTREMELY_ unclear whether Oracle possesses the will or expertise in house to continue with OpenOffice at the moment. [The commercial product - still StarOffice - appears to have died a lonely, unloved and unmourned death]. Hence LibreOffice: much of the patched code that never got back to sun, a vibrant community. A massively stripped and pruned codebase in a consistent version control system, stripping out much code retained by people keeping it around because they didn't trust the VCSes as they changed. [Michael Meeks pointed out in a blog post how many duplicated copies of icons LO had removed, for example]. In other news: it is possibly unsafe to use Java - it may become significa\ntly more expensive to do so. Virtualisation with VirtualBox is feasible today - but it looks as if it will effectively become a fully closed source product. I'm not sure that Oracle realised what goodwill they have thrown away or whether they know what they're up to. The move beyond a single database product and ancillaries has proved interesting. I personally am now significantly distrustful of Oracle as a company. I would actively suggest to anyone prepared to listen that they consider not doing business with Oracle and that they should stop buying or using any of Oracle's products. Likewise, for them to consider not recommending Oracle or their products to personal or business associates and not to be seen as otherwise supporting Oracle's activities in any way.

I thought the hardware business was the key point to buy Sun - to sell a database including the serving hardware. What's left otherwise? But you are right: they focus already on Intel machines only. -- Reuti > SGE doesn't fit their picture - a Sun OEM has stepped up to carry on development, all's well. > > In other areas, there have been forks, for good or ill. > > OpenSolaris was (fairly unceremoniously) canned and the "open source", non Oracle employee developer community, > such as remained, were effectively told they were not welcome.

A very nice summary, though one you missed out (and of relevance to this forum) is Lustre - there are plenty of rumours that Oracle are in the process of winding it up but (as usual with Oracle) there's no confirmation yet. At least there it seems a number of other organisations are willing and able to take it up - though that has risks of its own as Joe Landman ably pointed out.. http://scalability.org/?p=2921 cheers!
