The VALGRIND application verifying and debugging tool reports bugs in ACML that are false alarms.We believe this is due to one or more bugs in VALGRIND.Details and Recommendations.VALGRIND is a program analysis framework available online from valgrind.AMD is not associated with valgrind.We are not responsible for their product.Multiple users of ACML have reported that the VALGRIND tool reports bugs in ACML, such as Conditional jump or move depends on uninitialised valuesUninitialised value was created by a stack allocation.Usually, the subroutine acmlcpuid appears on the call stack.These reports are false alarms, caused by bugs in VALGRIND.AMD has investigated these reports and determined that the code is correct and these alleged bugs do not exist.In the valgrind online documentation at http valgrind.Using O0 is also a good idea, if you can tolerate the slowdown.With O1 line numbers in error messages can be inaccurate, although generally speaking Memchecking code compiled at O1 works fairly well and is recommended. Cheat Boo Or Boom Hacked Email on this page. Use of O2 and above is not recommended as Memcheck occasionally reports uninitialised value errors which dont really exist.Of course, the ACML libraries that we release are highly optimized for performance.Also, we observe that these false alarms usually point to code executed after a CPUID instruction.The x. 86 6. 4 CPUID instruction is unusual in that it writes destination registers EAX, EBX, ECX, and EDX, but those destination regiters are not explicitly encoded in the binary instruction code bytes.Unlike the destination for a typical instruction like add eax,ebx, the registers modified by CPUID are implicit in the opcode.VALGRINDs binary disassembler seems to be confused on this.The false alarms indicate that the VALGRIND tool does not understand that the CPUID instruction writes information into those 4 registers instead, the tool reports that they contain uninitialized values immediately after the execution of the CPUID instruction.Sincerely,The ACML team.Related Resourceshttp valgrind.KB1. 26.

How to use CPU affinity with Platform MPI on AMD based systems.Details and Recommendations.Q How do I enable CPU affinity with Platform MPI on an AMD based system A The general guidance here is that many HPC applications broadly fall into the category of being memory bandwidth bound in this case, you may want to use more memory controllers.This is referred to as the bandwidth affinity mode.This implies that tasks should be distributed across nodes and getting further away from the controlling node.Remember that each AMD processor is a NUMA node, with its own integrated memory controller and associated bank of RAM.Other applications may be more sensitive to the additional latency that can rise with spreading out, and in that case the latency mode may be better.These are the mpimon options that allow you to control affinity.The manual affinity mode is for manual placing of tasks, and it should be tried last after the other modes.N. N3 maps to the mask corresponding to these bitwise enumerated execution units in the node on a standard core enumeration, this would map to the four cores on a quad core.N. N1 maps to the mask corresponding to these bitwise enumerated execution units in the node on a standard core enumeration, this would map to the first core and third core on a quad core.There are several levels of granularity socket, core, and execunit.The concept of execunit applies to platforms with a chip level multi threading model and does not apply to AMD processors.Related Resources.Platform site http my.Platform email support msupportplatform.HPC Advisory Council Network of Experts msupportplatform.Related Articles.KB1. 15.
