私は次の問題を抱えています、私は2種類のデータ、1つのintと2つのcharを送信しようとしています、ここでは私のプログラムの一部です
#define Send(send_data, count, type, dest, tag) MPI_Send(send_data, count, type, dest, tag, GROUP)
#define Recv(recv_data, count, type, source, tag) MPI_Recv(recv_data, count, type, source, tag, GROUP, &status)
#define Recv(recv_data, count, type, source, tag) MPI_Recv(recv_data, count, type, source, tag, GROUP, &status)
#define Pack(data_in, count_in, type, data_out, count_out, pos) MPI_Pack(data_in, count_in, type, data_out, count_out, pos, GROUP)
#define Unpack(data_out, count_out, pos, data_in, count_in, type) MPI_Unpack(data_out, count_out, pos, data_in, count_in, type, GROUP)
#define Pack_size(count, type, size) MPI_Pack_size(count, type, GROUP, size)
#define MASTER 0
if( rank == 0 ){
k1 = strlen(prog);
k2 = strlen(gamesspath);
for( i = 1; i < proc; i++ ){
Send(&k1, 1, INT, i, 1);
Send(&k2, 1, INT, i, 2);
}
}
else{
Recv(&k1, 1, INT, MASTER, 1);
Recv(&k2, 1, INT, MASTER, 2);
gamesspath = malloc( k2 * sizeof(char));
}
Pack_size(k1, CHAR, &size1);
Pack_size(k2, CHAR, &size2);
Pack_size(1, INT, &size3);
buffer_size = size1 + size2 + size3;
buffer = malloc( buffer_size * sizeof(char));
if( rank == MASTER ){
pos = 0;
Pack(prog, k1, CHAR, buffer, buffer_size, &pos);
Pack(gamesspath, k2, CHAR, buffer, buffer_size, &pos);
Pack(&nindiv, 1, INT, buffer, buffer_size, &pos);
}
Bcast(buffer, buffer_size, PACKED);
if( rank != MASTER ){
pos = 0;
Unpack(buffer, buffer_size, &pos, prog, k1, CHAR);
Unpack(buffer, buffer_size, &pos, gamesspath, k2, CHAR);
Unpack(buffer, buffer_size, &pos, &nindiv, 1, INT);
}
/*FIM DO ENVIO*/
printf("PROG = %s, GAMESSPATH = %s, NINDIV = %d - rank %d\n", prog, gamesspath, nindiv, rank);
しかし、私は次の結果を得ています
PROG = GAMESS, GAMESSPATH = /usr/local/gamess/rungms1, NINDIV = 10 - rank 1
PROG = GAMESS, GAMESSPATH = /usr/local/gamess/rungms, NINDIV = 10 - rank 0
私の問題は、ランク1、/ usr / local / gamess / rungms1ランク0、/ usr / local / gamess/rungmsのGAMESSPATHにあります。
ランク1のGAMESSPATHの最後にあるように、番号1を表示しますが、エラーを見つけることができません。
