Hello, Jerome, Thanks for reporting the bug. We will fix it in the upcoming MPICH 3.1rc2 --Junchao Zhang On Nov 16, 2013 12:44 AM, "Jerome Vienne" <[email protected]> wrote:

Hi,

While trying to build MPICH 3.1rc1 with KNEM, I had the following error: *src/mpid/ch3/channels/nemesis/src/mpid_nem_lmt_dma.c(358): error: identifier "MPIR_CVAR_NEM_LMT_DMA_THRESHOLD" is undefined* * nodma = !knem_has_dma || data_sz < MPIR_CVAR_NEM_LMT_DMA_THRESHOLD;* *compilation aborted for src/mpid/ch3/channels/nemesis/src/mpid_nem_lmt_dma.c (code 2)*

I am guessing that the issue is coming from the name of the variable "MPIR_CVAR_NEM_LMT_DMA_THRESHOLD". Looking at the code, I saw that the name of this variable should be: "MPIR_CVAR_*NEMESIS* _LMT_DMA_THRESHOLD".

I did this change in my code and the build was ok.
