Intel® C++ STM Compiler Prototype Edition (Archived)

Internal error with -m32

I am running the intel64 version of Prototype Edition 3.0 on:

Linux bigowl 2.6.31-14-server #48-Ubuntu SMP Fri Oct 16 15:07:34 UTC 2009 x86_64 GNU/Linux

When I invoke icc with -m32, I get the following Internal Error:

Internal error: check_target_config: targ_size_t_max is too large

When I try the ia32 version on the same platform, it immediately segfaults.

What does this mean? How do I fix either problem?



I want know scope that memory access trace.

I write following code.



#define LOOP_COUNT 10000000
#define NUM_THREADS 2 /* should be an even number */

int th0_job = 0;
int th1_job = 0;

void* thread_body(void* arg)
int i;
int tid = *((int*)arg);

for (i = 0; i < LOOP_COUNT; ++i)

ICC STM, on Ubuntu, error: identifier "__tm_atomic" is undefined


I'm trying to use ICC STM prototype 3.0,
When I compile the examples on :
the compiler doesn't recognize the __tm_atomic, (error: identifier "__tm_atomic" is undefined)
Even when compiling with "Qtm_enabled Wall -lpthread",
Is the same syntax still used, I mean in GCC the syntax has been changed form "__tm_atomic" to "__transaction"

"internal error: backend signals" while compiling with Intel STM

Hi All,

I was trying to compile a program with Intel's STM ( prototype version 3.0).
My compilation command line was as follows
"intel/Compiler/bin/intel64/icpc -O0 -Wall -g -Qtm_enabled -c -o Cavity.o Cavity.cpp".

I got following error:

Tuple.h(84): remark #981: operands are evaluated in unspecified order
static double angle(Tuple a, Tuple b, Tuple c) {return b.angle(a, c);};

Cavity.cpp(141): remark #383: value copied to temporary, reference to temporary used

User undo action in TM

STM ABI says that function registered by calling_ITM_addUserUndoAction() is executedif a transaction is aborted or retried to allow the user code to undo any operations.
Is it possible to get pointer to_ITM_abortReason struct or to detect if transaction was aborted by user or retried inside this user-defined function?

Intel STM Compiler barrier optimizations

Hi -

The TM Compiler and Runtime ABI specification 1.0.1 states that the compiler could generate code without some barriers. In such a case, the compiler places speficic requirements on the runtime. (e.g. code without "after write" barriers requires an in-place update STM).

My understanding is that the Intel STM Compiler v3.0 implements this ABI specification but I am wondering whether it also makes the above relaxations (omitting barriers).
