[ilugd] KGPU
From http://code.google.com/p/kgpu/ KGPU is a GPU computing framework for the Linux kernel. It allows Linux kernel to call CUDA programs running on GPUs directly. The motivation is to augment operating systems with GPUs so that not only userspace applications but also the operating system itself can benefit from GPU acceleration. It can also free the CPU from some computation intensive work by enabling the GPU as an extra computing device. Modern GPUs can be used for more than just graphics processing; they can run general-purpose programs as well. While not well-suited to all types of programs, they excel on code that can make use of their high degree of parallelism. Most uses of so-called ``General Purpose GPU'' (GPGPU) computation have been outside the realm of systems software. However, recent work on software routers and encrypted network connections has given examples of how GPGPUs can be applied to tasks more traditionally within the realm of operating systems. These uses are only scratching the surface. Other examples of system-level tasks that can take advantage of GPUs include general cryptography, pattern matching, program analysis, and acceleration of basic commonly-used algorithms; we give more details in our whitepaper. These tasks have applications on the desktop, on the server, and in the datacenter. The current KGPU release includes a demo of GPU augmentation: a GPU-accelerated AES cipher, which can be used in conjunction with the eCryptfs encrypted filesystem. This enables read/write bandwidths for an ecrypted filesystem that can reach a factor of 3x ~ 4x improvement over an optimized CPU implementation (using a GTX 480 GPU). KGPU is a project of the Flux Research Group at the University of Utah. It is supported by NVIDIA through a graduate fellowship awarded to Weibin Sun. More We have a short whitepaper describing the motivation and design of KGPU. The idea behind KGPU is to treat the GPU as a computing co-processor for the operating system, enabling data-parallel computation inside the Linux kernel. This allows us to use SIMD (or SIMT in CUDA) style code to accelerate Linux kernel functionality, and to bring new functionality formerly considered too compute intensive into the kernel. Simply put, KGPU enables vector computing for the kernel. It makes the Linux kernel really parallelized: it is not only processing multiple requests concurrently, but can also partition a single large requested computation into tiles and spread them across the large number of cores on a GPU. KGPU is not an OS running on GPU; this is practically impossible because of the limited functionality of current GPUs. _ Best A. Mani -- A.

Re: [ilugd] [OT] KGPU
Well why Government of India cares, they don't need Supercomputer, as they don't have any use of it. I don't think its fair to blame Government for this. It should be private corporation / entity effort. Funding for this research will depend on the service need. --Naresh ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
Re: [ilugd] KGPU
hi all, there are few unanswered question/clarification . As i undertand 1. GPU is not an alternate to CPU(i dont know someone got confused there) . 2. GPU is a additional unit like math coprocessor so it can not be considered to be part of core OS as kernel already is bloated with so many additional things to do then it's core funcinality. if we add load balancing and manging of threads also it is going to be an overkill. Ideally kernel should be doing only scheduling(remember famous argument between linus and tanenbaum long time back ) 3. in linux threads are inherently processes so in sense we are working with multiple processes. 4. GPU does not distribute the logic . to solve the problem using GPU it need to be broken down into parallel threads of execution . there fore if the applications are not written with GPU in foresight it would not be able to gain the speed up factor on the contrary we might loose more execution cycles due to overhead. 5. not only govt of india many enterprises aslo need it. for example i remember param was used for weather forecasting,other uses can be datamining etc 6. supercomputer and clusters these are now used interchangeably design wise they are different like cray series super comps etc. though if you want to keep teraflops as the count cluster may give an impression of better performance but inherntly it would require the problem to be broken down and parallelised before computing. I did a cluster for CDAC Noida for there teaching needs in 2003 based on OSCAR http://svn.oscar.openclustergroup.org/trac/oscar also showcased the improved results using linpack. it was made of old pentium boxes and used to do PXE boot. though it was not a supercomp. these clusters are considered as supercomps and many enterprises do it that is the reason you would see so many people doing supercomps. 7. Now in the era of multicore and co processors like GPU the scaling can be better but first we have to break down the problem to identify bittlenecks and parallel threads of execution.It needs lot of testing and benchmarking to see the result. 8. there are so many things in the kernel like NUMA etc which help better performance then an additional processing unit 9. i would like to know how and where GPU is used in software routers as mentioned in the write up this would be interesting as software routers now days use vitualised enviornment to see better performance .Using GPU will it be better then virtual enviornment. 10. also in packet processing we do lot of parallel processing and in Network processors we handle lots of things mentioned in the hardware itself how is GPU better then those there are lot of things i can go on and on but i think i would stop now :) Regards, Abhishek Kumar Date: Sun, 8 May 2011 23:56:30 +0530 From: bhushan...@gmail.com To: lists.ni...@gmail.com CC: ilugd@lists.linux-delhi.org; linux-discuss...@ilug-cal.info Subject: Re: [ilugd] KGPU I have done GPU Programming, when i was at CDAC. the performance of ISRO GPU based Super Computer is only theoretical. I asked Dr V C V Rao, when i was at CDAC, about the performance of GPU based on current CPUs and the hardware support. He said to me what GPUs do, they create a number of internal parallel threads to solve the calculation and give the response immediately. But still their performance is hampered by speed of internetwork, the CPUs dividing the job and the type of job to be divided. The real test of the performance of a Super Computer can done by following the LINPACK benchmark test. Lets see how much performance this super computer gives on this benchmark. Dammn the fastest of India is at 47th rank.(God it was on 11th rank when i saw it last time). what is happening to this world, everybody are making supercomputers.

From: Sirtaj Singh Kang sir...@sirtaj.net Hi all, I am looking for a web-based frontend to manage an LDAP-based user and host database. There are a lot of options out there, but ideally: 1. It should come prepackaged on debian and be well-maintained and up to date. 2. Shouldn't be a MANAGE EVERYTHING front-end - I'd like to maintain focus on LDAP. 3. It should support all the basic Linux schemas so that users can be set up to log in via ssh etc. Hi, phpldapadmin (http://phpldapadmin.sourceforge.net/wiki/index.php/Main_Page) worked well for me.
