EM64T compiling options?
Hi, I'm migrating from an i686 to an EM64T machine (Intel core 2 quad) and I'd like to know whether there are specific options that I can pass to gcc for an optimization of my code or if everything is blindly set up. How would I manage the 4 cpu cores if I was to write in assembly? Thank you in advance for any link or information on this subject.

How would I manage the 4 cpu cores if I was to write in assembly? GCC has a lot of optimization/architecture flags. Just have a look here [1]. However, this won't make your software use the 4 cores. You should use threads or multiple processes with IPC. I don't know what you want to do but I think you should forget about writing in assembly and use an higher level language. You probably don't need assembly at all. Moreover, higher level language have sometimes concurrency and synchronization facilities which will help you getting the most of your 4 cores.

Re: EM64T compiling options?
Many thanks, I'll read your link with attention. Do you have further links on threads and IPC ? I'm thinking in rewriting an old and unfinished logical interpreter in C that used assembly code (nasm) for truth evaluation of the smallest elements. I'd like also to create a small database for prime numbers (using John Moyer's storage code) in order to test several things on prime numbers distribution.

You might write a critical section of code in assembly, but all the glue ought to be in C, inluding anything to manage pthreads to do multiple threads, which is how you take advantage of multiple cores. As for optimizing, there really aren't any options yet since there are very few amd64 designs so far and they all have the same instruction set and features pretty much and hence the code should be pretty much optimal for all of them (in as much as gcc produces optimal code for anything). -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

AFAIK it use pthread to work but it create all necessary pthread at startup to avoid creating them at each loop parallelization. It should work properly with pthreads, it wouldn't be packaged with gcc if it wasn't the case. However I didn't test this combination. openmp is really simple to use, easier than programming the same thing with pthreads. You can see examples on wikipedia : http://en.wikipedia.org/wiki/OpenMP The purpose is to do simple parallelization. If you want to write an algorithm which needs modification to support multi-cores, you have to do it yourself with pthreads.

Re: EM64T compiling options?
There is an environment variable GOMP_AFFINITY in libgomp that binds threads to single cpus. Can I use it the same way with multi-cores (i.e GOMP_CPU_AFFINITY=0 1 2 3 in order to bind thread 1 to core 0 etc..)? Is this a good way to take advantage of the quad architecture?

Optimum kernel for Xeon with em64t
Hi There, I have a dual processor server with 2 x 2.8GHz processors which supports EM64T. Currently i am running kernel 2.6.8-9-em64t-p4-smp and a cat /proc/cpuinfo shows 4 processors (the 2 hyperthreaded processors). My question is: What is the optimum kernel to be running for my setup? Am i running the correct one? This is a mail server that has debian sarge installed and runs dbmail/amavis/postfix and supplies incoming and outgoing mail for our clients - is there even a reason here to run a EM64T kernel in this case?

Well given this, I would do the following: 1) run fsck on all partitions just to be safe 2) get the 3ware controller to run a verify background task and watch the 3ware logs to see if you are getting sector repairs or errors on any of the disks. Also you might have a run diagnostics background task that might give some insight to whether the controller is sane or not. 3) setup a serial console to capture the console logging on another system so you can look at what the kernel messages are as Lennart suggested. -Steve W. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I don't know how you would tell in that case. Most of these flags are not set simply because the kernel found a certain type of processor. They are the result of elaborate startup tests which detect these capabilities. If a capability is disabled in the bios, two things can happen 1) the kernel does not detect it at all; in which case the relevant flag is not set; 2) the kernel detects the capability but switched off; in which case the kernel will attempt to switch it on (if it can of course). If this succeeds the flag is set, if not you will often see an error and the flag is not switched on. I have been told, however, that a few processor capabilities are so bound to the a certain type of cpu that their flag is simply set if that cpu is found. I don't know under which category the hyperthreading flag falls, but knowing that hyperthreading can be disabled in the bios, I would not expect the kernel to simply set that flag blindly. I think that's all wrong. The flags are more or less a decoding of the CPUID result codes. As for HT, my dad's old laptop 1.7GHz P4-mobile (Northwood) has the ht flag, but it sure as hell doesn't have two logical CPUs. I looked at (but didn't really come close to understanding ;P) the relevant kernel code, and I think the ht flag indicates support for an API for asking how many logical CPUs there are, and so on, not that there actually are multiple logical CPUs on that physical CPU. The kernel log messages (look in /var/log/dmesg if other messages have bumped them from the ring buffer) are more useful than the ht flag.

Re: Upgrade to Kernel 2.6.8-11-em64t-p4-smp
my experience was that the difference between 2.6.8 and 2.6.11 was enormous for amd64 (although it might mainly have been for nforce based boards), since 2.6.11 things have really only just got more tidy (ie my mboard sound being specifically identified rather than just identified by its generic chip) im sure there are deeper architectural changes that are of benefit also. i recall nvidia whinging about changes that broke their drivers. but thats really their own fault.

Most of these flags are not set simply because the kernel found a certain type of processor. They are the result of elaborate startup tests which detect these capabilities. If a capability is disabled in the bios, two things can happen 1) the kernel does not detect it at all; in which case the relevant flag is not set; 2) the kernel detects the capability but switched off; in which case the kernel will attempt to switch it on (if it can of course). If this succeeds the flag is set, if not you will often see an error and the flag is not switched on. I have been told, however, that a few processor capabilities are so bound to the a certain type of cpu that their flag is simply set if that cpu is found. I don't know under which category the hyperthreading flag falls, but knowing that hyperthreading can be disabled in the bios, I would not expect the kernel to simply set that flag blindly.

I believe the was a short time when a bug in mkinitrd would load it when it shouldn't. You could try booting with the kernel option for making ide-scsi ignore hda, or you can try regenerating the initrd and see if it does something smarter this time. The initrd should NOT be loading ide-scsi so that is what the problem is. You could add your current hd controller and the ide-cd drivers to /etc/mkinitrd/modules and then regenerate the initrd and hopefully on next boot it will be better behaved since those drives should then load first.

Nice server board for AMD64/EM64T?
Hi. I'm going to replace a server (keeps crashing due to some unknown reason since about a month, ran for 1year rocksolid before - I was able to limit the source to be one of mainboard, processor or RAM), and because I definately want hardware RAID and already have 8 HDs in the old server (a total of approx. 0.9TB usable), I will need an additional controller anyway, even without doing hardware RAID. Anyway: Can anyone give me recommendations for a nice board which features: 1) 2 Gigabit Ethernet ports 2) at least one PCI-X slot (if no GB-Ethernet available: 2 PCI-X slots) 3) support for a AMD64/EM64T processor Alternatively, I would be interested in recommendations for a nice SATA controller with at least 8 channels. I currently tend to a 3ware 9005-8 or -12 because I had a very good experience with my current 3ware 7508. However, if someone can recommend a good (and obviously: Linux supported) SATA controller for PCIe, I would be interested in a recommendation for a matching mainboard. Price is of course important, but stability and Linux support are far more important. I.e. given the choice between a 250$ combination of mainboard and SATA controller which runs only _mostly_ stable, and a 1000$ combination which runs _completely_ stable, I would choose the latter. cu, sven signature.asc Description: OpenPGP digital signature
Re: Nice server board for AMD64/EM64T?
Tyan Thunder K8SR S2881. I have one of them running under Linux in a high load mail server for months now without any problems. Using Opteron 248s (bought it when those were the 2nd fastest Optis). Chipset is also AMD, long in production, very reliable. NICs: two Broadcom BCM5704C, GBit. Plus we have close to 20 of them running under W* with two Opteron 265s. Stable as can be. They eat every Intel offering in every respect - power draw, performance, price. The board starts at €404, this ones is for 1U with only two slots. There are almost identical boards with more slots like Thunder K8SD Pro S2882. I found this one for only €370, -D version is recommended as it supports DualCore (I think the non-D have disappered from the market). For SATA RAID, I use LSI MegaRAID SATA 300-8X, becuase 3ware 95xx doesn't fit into the Tyan 1U chassis (too long with SATA cables connected). The LSI so far runs perfectly (kernel 2.6.11 needed) so far, but only for some weeks by now. Sönke

Has anyone had the opportunity to benchmark this, or have any real experience with changing the underlying platform? Our experience with IBM HS20 blade servers shows the 2.4 GHz Opteron blows the 3.2 GHz EM64T out of the water on our bioinformatics codes, which are predominantly limited by integer performance and memory bandwidth. And uses a lot less power (this is significant when you have about 1000 processors in the cluster!). No more EM64T for us, at least for a while. One thing to be careful with, if it's a dual CPU opteron machine that you're benchmarking, is that you need a really up to date kernel that gets the NUMA topology right; our initial benchmarks were disappointing, and it turned out that the the numa topology stuff in the kernel was exactly backwards, so every process was always accessing memory local to the other CPU. This has been fixed in recent kernels. Tim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Intel EM64T vs. Opteron

First off, I am a user of Debian-amd64 right now - and I love it. I run it on Opterons. It screams. I have a chance soon to switch out my servers, and going the Intel route I would be able to get a lot more bang for my buck. The website says that EM64T works fine with Debian-amd64, I just want to make sure there's no gotchas, compared to using it on an Opteron-based system.

Has anyone had the opportunity to benchmark this, or have any real experience with changing the underlying platform? I can build an 830D based system with dual-cores for cheaper than a single-core Opteron box right now (I have some discounts) but if the performance isn't as good as it seems it should be, or there's some odd things that must be done to get EM64T to work properly under Debian-amd64, I'd like to know that before committing to the hardware choice :) I plan on running the latest Linux kernel 2.6.x - two of my servers will be LVS machines and I will have a handful of webservers running this platform, in case you're wondering about specific usage.

From what I have gathered reading this list, the P4/xeon slows down a little in general when you enable 64bit mode. AMDs speed up. Given the AMD is usually faster at mosts tasks already in 32 bit mode, the situation is not improved (for intel) in 64bit mode. Remember you can not compare an 830D to an opteron. That's like comparing an 830D to a xeon. Rather unreasonable comparison. Compare it to an Athlon 64 X2 system. I plan on running the latest Linux kernel 2.6.x - two of my servers will be LVS machines and I will have a handful of webservers running this platform, in case you're wondering about specific usage. Thanks in advance for any feedback! To me the netburst architecture looked wrong when it came out. I still think it looks wrong and I will be happy when intel finally dumps it for the pentium-m based architecture in their server and desktop lineups. Until then I will buy what is the fastest (and cheapest) systems you can get, which is AMD based systems. Of course I haven't been buying dual core, which do seem rather pricey relate to single core. for example: Asus A8V Deluxe $132cdn AMD Athlon 64 X2 3800 $440cdn AMD Athlon 64 X2 4800 $1066cdn 2 x 512MB DDR400 $122cdn 2 x 1GB DDR400 $330cdn Total is $694cdn (3800 1GB) to $1528cdn (4800 2GB) Asus P5LD2 $153cdn Intel Pentium D 820 $314cdn (2.8GHz) Intel Pentium D 840 $670cdn (3.2GHz) (I am ignoring the extreme edition as being silly expensive) 2 x 512MB DDR2-533 $140cdn 2 x 1GB DDR2-533 $280cdn Total is $607cdn (D820 1GB) to $1103cdn (840D 2GB) Video, HD, case, etc should be similar between systems and hence not relevant. An X2 3800 = 2xAthlon64 3200 (which in my experience is easily faster than a 3.2GHz P4). An X2 4800 = 2xAthlon64 4000. The 4600 is the same but with half the cache. Given the more efficient memory interface of the athlon64 x2 than the shared FSB 830D, and that the 3800 is a dual of a cpu that already is as fast as the single core in the 840D, it is actually fair to compare the X2 3800 to the 840D (which costs more of course). The 820D and 830D might be cheaper, but they will also be slower for probably just any any task you throw at them.

When did xeon servers become cheaper than opteron servers? :) Please note the I have a chance line - I have some discounts that I can apply against Intel 830D's which would take the overall cost down to less than an Opteron machine - and I'd be getting dual-core for that lower price as well. Pentium 4 830D's have EM64T support; it's not just Xeons. Remember you can not compare an 830D to an opteron. That's like comparing an 830D to a xeon. Rather unreasonable comparison. Compare it to an Athlon 64 X2 system. You can compare anything you want. It's a comparison for that reason. My two options are an 830D or an Opteron-based system. The main question is 64-bit support using Debian-amd64/kernel 2.6.x. Is it any different than installing Debian-amd64 on an Opteron box? I already run it on 7 Opteron-based systems and an Athlon64 system. From the replies after this, it sounds like the EM64T 64-bit arch is a little slower than AMD64. However, maybe that's just a bottleneck that will be fixed soon, much like when Hyperthreading came out?

I already run it on 7 Opteron-based systems and an Athlon64 system. Installing should be exactly the same as long as the chipset and such in the machine is supported in 2.6.8 kernel (or 2.6.12 if you use my version of the installer). From the replies after this, it sounds like the EM64T 64-bit arch is a little slower than AMD64. However, maybe that's just a bottleneck that will be fixed soon, much like when Hyperthreading came out? No, I don't think the current em64t design will ever run faster in 64bit than 32bit. The opteron/a64 was designed from scratch with 64bit in mind. The netburst architecture wasn't. It had to be modified to handle 64bit without a complete redesign from scratch. It is however from what I gather not a particularly noticeable difference, and if the program has any advantages from 64bit (like using sse for floating piint instead of x87) and using more than 4GB memory mapped, then it should be worth the slight drop in speed.

LGA775 socket E7230 chipset it appears - i think i saw another model or two that may have slightly different chipsets, but i can't find them now. anyway, from the discussions it sounds like Opterons are just a better choice for now, based on this and some other collateral and forum posts i've been able to google up.
