Hi, We have the same difficulties. KNC (dubbed k1om in compiler utils) is a 64-bit device with 8087-compatible scalar arithmetics and non-standard vector arithmetics. More specifically, the widely used variant of 64-bit ABI implemented by LLVM involves xmm registers, while KNC does not have xmm-s and instead has zmm-s (512-bit wide). Th...

Hi, in the past few weeks we were able to confirm that the LLVM's JIT compiler can be used for our research project. This was confirmed for x86-64 architecture (with very good performance results by the way). Now, one of our real target architecture is the Intel Xeon Phi (KNC) accelerator in a native execution model. When cross-compiling LLVM (3.4 RC1) for Xeon Phi with CMake following the Intel guidelines (for general cross-compilation), the compilation process stops with [ 88%] Building CXX object lib/Target/X86/CMakeFiles/LLVMX86CodeGen.dir/X86ISelLowering.cpp.o...

Hello, I have a few issues in vectorizing loops using Clang 3.8. Will it be ok if I shoot some of my findings and queries here? Meanwhile, can I please know if LLVM support autovectorized MIC instructions for Xeon phi? If so, could you please tell me the flags to use? I am Jumana, a masters student in Embedded system working as a graduate research intern with Intel. For my thesis, I am working

Hello Elena, > There is no 32-bit KNC. Are you sure about this? From "System V Application Binary Interface K1OM Architecture Processor Supplement Version 1.0", p. 124: | A.1 Execution of 32-bit Programs | | The K1OM processors are able to execute 64-bit K1OM and also 32-bit ia32 programs. I'm really really looking for...

1) Is there actually a 32-bit mode for MIC? 32-bit ELFs are not recognized, so... There is no 32-bit KNC. 2) MIC ISA is 32-bit ISA (no SSE/MMX) plus 256-bit AVX-like vectors? No, 256-bit vectors are not supported. KNC is scalar ISA (Knights Corner supports a subset of the Intel 64 Architecture instructions) + 512-bit vectors + masks 3) then does MIC calling convention permit generation of programs...

...Since Knights Landing (KNL) is going to be shipped also in form of host CPU, it will have to have open-source support :) But given that KNL is only announced 1 month ago, we should expect up to 1.5 years for it to become somewhat wide-spread, i.e. 2014-2015. Meanwhile, I still hope to perform some KNC evaluation, so answers to above questions are much appreciated!

Hello Dmitry, I'm working on KNL backend and plan to push it to the open source once the ISA becomes public. We do not plan to support KNC architecture in open source. - Elena -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Dmitry Mikushin Sent: Friday, July 12, 2013 01:51 To: LLVM Developers Mailing List Subject: [LLVMdev] LLVM x86 backend for Intel MIC : trying...

Dear all, I'm interested to analyse what could be done with current LLVM trunk to deliver basic Intel MIC support. Let's say, for basic level we'd want just scalar code execution, no threading, no zmm vectors. Attached verbose in text, but functionally very simple patch copy-pastes x86 and x86_64 backends into 32-bit and 64-bit K1OM. In the end of the message you can find how simple

It's very nice to see that NUT now supports my Belkin Universal UPS. Great work! Now I'm wondering if there's a GUI client that will build/run on a modern distribution. KNutClient requires an outdated version of Qt, and the "UPS Monitor" link leads to a Spanish error page. Thanks! -- ======================================================================== Ian Pilcher

Hi, Updated to current bk today, and my machine stopped booting ... I''ve tracked it down to the apic changes from end of last week. cset 1.1307 boots fine, 1.1308 doesn''t. Diff of the boot messages is below. Full logs are also attached. Gerd --- log-1.1307 2005-04-21 14:40:57.372885027 +0200 +++ log-1.1308 2005-04-21 14:38:52.236553392 +0200 @@ -7,7 +7,7 @@
